Help Me Choose A Portable Car Jumper Kit.....

[walker2713]

I want to get a couple of the portable auto jump start kits to keep in our cars. I did an Amazon search, and there's a ton of products available....but pretty confusing.

Mine is a Toyota 4Runner and she has Lexus RX350.

All help and input appreciated!

Search Rugged Geek RG1000 on Amazon. We have them at work and they work great in my experience. If you get the one with mini compressor, it all comes in a nice case too. I plan to purchase a couple for my cars, just haven’t got the funds yet.

This makes me geek out and wish for a plethora of features, like weather radio perhaps? I like the manual charging capability of this one (https://www.amazon.com/s/ref=sr_hi_4?rh=n%3A15684181%2Cn%3A!15690151%2Cn%3A 15706941%2Cn%3A387679011%2Cn%3A318336011&bbn=318336011&ie=UTF8&qid=1509714339).

I saw a lot of good reviews and picked one up. Right after the Amazon return window closed, I had to use it (little over a month). Battery was at 23%, which shouldn’t have occurred (1-2% loss per month). Used the compressor, burnt up within five minutes. Emailed Rugged Geek, sent a new kit the next day after I sent the Amazon order number.

New one seems good. Warranty is good, but have to see how a good one goes. Can’t really base my opinion on a bad apple.

I appreciate you sharing your experience. I don’t have much experience with these things, just going off what I have at work. I can say that at 72%, I was able to easily jump a full size truck with a V8 that was almost completely dead. I don’t know how long it had been since that jumper was charged or used either. They kinda just sit in the trucks unless someone takes the initiative to check/charge them, and they don’t always get charged after being used. I have never used the compressor so I can’t comment on it’s durability.
I your replacement works out better for you!

I've got a Booster Pac ES5000 that my dad got me years ago. It still holds a charge well and has enough juice to get my car going (both my previous car and current car have Group 65/650-750 CCA batteries).

I shy away from the all-in-one tools just from seeing them as doing a lot of jobs okay but doing none of the jobs well. I carry a separate Viair 12V compressor for airing stuff up and separate battery powered radios. Same footprint as the all in one, but more versatile and probably a little better off than having something fail and cost me all three items instead of one.

I have had good luck with a Suaoki 18000 mAh 600A T3 I bought from Amazon in Jan 2016. Its performance has been quite impressive - hook it up to a dead battery, turn the ignition key and start the vehicle. The unit I bought came in a sturdy box with a small compressor and multiple connectors for charging various devices. The compressor works, but very slowly, especially with tires such as those on light trucks.

[walker2713]

Thanks for the feedback, guys....very helpful!

I recommend the Battery Tender Jump Starter: https://www.amazon.com/Battery-Tender-Lithium-Portable-030-0001-WH/dp/B00Q2E2QF0/ref=sr_1_1?rps=1&ie=UTF8&qid=1506223085&sr=8-1&keywords=battery+tender+jump+starter&refinements=p_85%3A2470955011

Small, but gets the job done well. Also, it has an override switch for the reverse hook up protection. That's important because if the battery is 100% dead, jump packs with reverse hook up protection read no charge like a reverse book up. Without an override capability one of those jump packs becomes useless.

I never thought about that, and that's a really, really good nugget of information.

[rayrevolver]

Figured I would share this. I don't have one (carry cables in my truck, wifes car has nothing though) but thinking about buying the $69 1000amp version. How do you keep it charged if its stored in the trunk? Does it become one more thing to have to charge every week/month? Maybe it becomes something that is charged and packed for road trips just in case.

NOCO Boost for $59/$69.

[mtnbkr]

Rayrevolver beat me to it! I was thinking about that Woot ad when I saw this thread. Better act fast, it may not last all day (and will definitely be gone tomorrow).

I have the 1000amp model and used it in anger last Fall to good effect. I would buy it again.

Chris

[rayrevolver]

I ordered the GB40 1000amp. Having one handy at home makes jumping much easier as well.

Per NOCO, it will hold up to a 70% charge for 1 year and they recommend charging every 4-6 months. Thats not too bad and something I can keep tabs on for the wifes car.

I also read it has a manual override so you can boost a dead battery.

[fixer]

I use Jump and Carry and went out of my way to avoid lithium ion.

[hufnagel]

I picked up the Harbor freight Viking Lithium Ion Jump Starter and Power Pack (https://www.harborfreight.com/lithium-ion-jump-starter-and-power-pack-62749.html?_br_psugg_q=jump+starter) a while back, on sale for $60 with coupon. It worked on my Jeep and the wife's car once each so far.

I see questions about long term keeping it charged. Mine sat for 6 months before I used it, and it worked fine. When I do some wiring bits on the jeep I'll be putting in a switched 12v outlet dedicated to keeping the pack plugged in and charged though.

[whomever]

Based on a friend's recommendation we got a "GOOLOO 1500A Peak 20800mAh SuperSafe Car Jump Starter" a couple of years ago. The one time we needed it it worked. I didn't do a deep dive on them.


(and glad we were ... I was more a jumper cable kind of guy, but the time we used it we were at a remote trailhead)

[JAD]

I own and have used https://smile.amazon.com/dp/B015TKUPIC/ref=cm_sw_em_r_mt_dp_U_3AfiFb5F8MSKK several times, including manual override on a completely dead Jetta. Works good, and is also a hell of a power bank if you need (I have used it camping). Lithium ion batteries don't self-discharge much -- all that eats charge is the quiescent current of the BMS, and that should be really low for small simple packs like these.

[OlongJohnson]

I picked up a NOCO on a Black Friday deal. Thought it would be convenient to use it to power some non-automotive 12V equipment. Good thing I tested everything beforehand, as it delivered bupkis. I tested it on a battery that would sink some current, and it did fine. But the "safety" features of the programming that keep it from blowing up if you hook it up backward or short the terminals also makes it a paperweight if it's not hooked up to a significant load. Something basic like a radio, small light, etc. won't run.

Note this does not reflect on its utility as a powerbank for running USB stuff.

EDIT EDIT: Maybe this is not a good idea to try, what I mentioned below? I don't know. Don't zap yourself man!

I am not 100% sure since I don't have my NOCO in hand, but the override function will allow you to use it as described above for anything that is 12v. The override is designed to power a completely dead battery and removes all protections.

If you still have the NOCO I would love to hear if this works. Mine shipped but USPS has slow rolled my last 2 packages, one shipped 7 July and still not here.

EDIT: Found this accessory, but says its not compatible with the GB40???

I've been running a NOCO for a couple of years. It's started up everything, including some diesel delivery trucks at work.

Yeah, I have the GB40. It only has the main 12V port. The others are USB IN and USB OUT.

[rayrevolver]

At a friends place and another buddy left his lights on since yesterday. He asked for jumper cables and I remembered the NOCO. My GB40 was charged in early August and has been in the trunk of the wifes car ever since. Not gonna lie, I was excited to put this thing to the test.

A few guys said it would never work. Hyundai started on the first try. Pretty damn cool.

Has anybody had issues with the NOCO unit being dead when needed? I've read enough of these reports on amazon and elsewhere to give me pause.

I’ve had my sit for 6 months and then fire up a car no problem.

Having batteries do that just seems weird. I am used to old school lead acid rechargeables that lose 5% or something like that each day not on a charger.

I still carry jumper cables but I am old school like that.

I keep my battery charged with a Battery Tender Plus. (I had a Battery Tender Jr. for 25 years which just gave up the ghost last week.)

(I also keep jumper cables in the 4Runner, but have been intrigued by the idea of these NOCO (and similar) units.)

I would do it. I got one for my wife’s car after we got back to our car at the airport in winter with the 3 year olds in tow. One of them had turned on a dome light before we left. We waited for 45 minutes for the parking lot service to jump the car. No other folks were around at the small airport.

My wife has used it multiple times and it has been a real time and inconvenience saver. You’ll have to check but the $100 will jump most cars.

[rob_s]

Looking at these Noco brand, what size do you need to jump a v8 in a full-size truck? I got a different brand as a gift awhile back and it won’t work on my truck.

[whomever]

"Has anybody had issues with the NOCO unit being dead when needed? I've read enough of these reports on amazon and elsewhere to give me pause."

We got one (a 'GOOLOO 1500A Peak 20800mAh SuperSafe Car Jump Starter with USB Quick Charge 3.0') a couple of years ago, and a few months later the battery died (defective battery, replaced under warranty) on a 6 month old F150 ... parked at a remote trailhead, making the jumper cables kinda useless :-( ). It started right up. Non a NOCO, but it has similar ratings.

It's been sitting in the car since then, so 12 to 18 months. I just went out and checked it and it powered up and says the battery is at 99% (which seems odd, I would have expected some self-discharge). I don't have any way to actually load test it, but at least it isn't completely dead.

I dunno if I'd spend the $$$ for a car that spends its life in town, where you can always usually get a jump and/or have cell coverage, but if you go to out of the way places they seem like a real good idea. Ours was $70 ... beats walking 20 miles.

The one-star ratings do give me pause. I think they do overstate the problems, i.e. something that has 10% one stars probably doesn't fail 10% of the time - people who have a problem are more likely to post a review than those for whom it works, I'd think. That said, I'd rather buy one with 1% bad reviews than 10%. Unfortunately, there may not be a brand built to that level.

As far as what size you need, FWIW, the motor was a 2.7 ecoboost. No mechanical etc. problems, so it started more or less instantly.

[vcdgrips]

FWIW. I too recently picked up a NOCO GB 40 as my 95 Jeep's 5y/o battery had given up the ghost and it is not being driven much. I went ahead a bought a new battery and had it in before the jumper kit cam in the mail so it never got a trial run. I got if for a bit less than the present 99ish so you might want to watch it a bit to see if the price comes back down on Amazon if time is not of the essence.

PS-I still carry jumper cables and do not see that changing.

[whomever]

"I got if for a bit less than the present 99ish so you might want to watch it a bit to see if the price comes back down on Amazon if time is not of the essence."

FWIW, there is a site called 'camelcamelcamel' that tracks amazon prices:

https://camelcamelcamel.com/product/B015TKUPIC

You can give it an email addr and price, and they will email you if the item goes under the price you set.

[Dog Guy]

I've been carrying one of these for the last two or three years. On two occasions it started my Dodge Cummins diesel when the battery was too dead to even get a click from the starter. https://antigravitybatteries.com/products/micro-starts/xp-10/ We spend a lot of time out alone in the sticks so a good jump kit is worth the coin.

I got excited about having a 'milspec' brand available, then I checked on Amazon ... they don't have many ratings and unfortunately seem to have a similar number of 1 star ratings as the other brands.

The link a few posts up has general guidelines under each model.

The GB40 does 6.0L gas and 3.0L oil burners. I have a 3.5L ecoboost and the wife has a 2.4L Toy... and the GB40 was on sale.

GB50 is 7.0L gas and 4.5L diesels.

Somewhere in this thread we talk about having the ability to run 12v items from these, but my GB40 does not do that. If that is something you want, then you might need to swing over to NOCO.

[mtnbkr]

Resurrecting this because I just had to use the NOCO jumpstarter that I referenced above for the 2nd time. I came home yesterday afternoon to learn the battery in our minivan had died without warning (was fine when we parked it a few days prior). Battery was showing 9.5v via a multimeter. Out came the NOCO... I checked the current charge status on it and saw that it was 75% charged after sitting a year in the storage compartment of the van. I hooked it up. Let it sit a couple minutes, then cranked the van. It fired right up. I let it run till the temp gauge came off the bottom of the scale, killed the engine, and tried starting it without the NOCO. No dice. Battery is toast. But, the NOCO got it running again and that would have gotten us home had we been out and about.

I'm going to get another one for my 4x4. Not only does it work, it will hold enough charge after a year of sitting to get an engine started. That's especially important for my 4x4 that might sit for months at a time.

For info, the van has a 3.5L V6 and the battery was so dead is didn't even make the starter "click".

FWIW, I paid Amazon $71.94 plus tax for the GB40 back in early August.
Had it in my cart for a few weeks and grabbed it when the price dropped from like $99.
Haven't had to use it yet, but, having it on hand brought some peace of mind on 2 long trips over the last few weeks.
It was a bit strange charging the thing with a USB wall charger. :rolleyes:

Thanks, Chris. That sounds adequate for the 6 cylinder 4Runner.

Did you have to use the "manual" setting for the charger since the voltage was so low?

I just hit the power button to check the charge level, connected it to the battery, let it sit for a minute, then cranked the engine. It struggled for a brief moment, then cranked and fired up.

Take a look at the Weego 66 (https://www.amazon.com/Starting-Cranking-Performance-Flashlight-Resistant/dp/B07GT4DGS5/ref=sr_1_2?dchild=1&keywords=weego+66&qid=1601508396&sr=8-2). While I have not gotten to use mine yet, I bought it based on a strong recommendation from a State Trooper friend who has used his on countless vehicles and absolutely loves it. Very easy to follow instructions for those of us who are not very automotively inclined. I carry this now in addition to a solid set of 4 gauge cables.

[DamonL]

I watched someone jump start their minivan using a jump start battery last weekend. It jump started me to buy one. I just ordered one of these, a Gooloo GP37. Its on sale for the next few hours at $10 off.

https://www.amazon.com/GOOLOO-18000mAh-SuperSafe-Starter-Portable/dp/B0748D8KT6?ref_=Oct_mh_s9_apbd_orecs_bLXhjn&pf_rd_r=98344BVZT9P02NAH9N04&pf_rd_p=0f689746-a2ef-5724-a925-3e188bccda2d&pf_rd_s=mobile-hybrid-11&pf_rd_t=BROWSE_ANYWHERE&pf_rd_i=318336011

Its spec is between the NOCO GB40 and GB50. And it costs less.

[blues]

The bad reviews give me pause. I think I'll stick with my jumper cables.

(Battery Tender Plus keeps the battery maintained if the vehicle's not being used for a period of time.)

Jumper cables are great when there's someone else to provide the power and the vehicle isn't in some position that prevents them from reaching.

I keep jumper cables in all of my vehicles, but the little jump kits are just so convenient and will work even if you're alone.

Totally get that. I guess what bothers me is not knowing if something I've had on hand for months or a year without needing to use it, will work when called upon. (And not having the option of a warranty to replace it if it doesn't...which would be money wasted on top of the aggravation of being stuck.)

I know all about being out in the middle of nowhere with no one around to help. Been in areas out west where I didn't see another vehicle for several hours on the road, let alone once I got off the highway.

Very tempted...but leery.

[JAD]

I make my living off of cheap POS batteries (made by our competition) catching on fire, but I don’t think that’s a serious concern with these, and I have one in my trunk.

It might work (it probably will — I use it as a power bank from time to time and that keeps it topped off), and it takes up little space. I’ve used it three times to good effect.

Other than the fire hazard and the cost of two boxes of ammo, what’s the harm?

So let’s say you’re out there all alone and DON’T have a battery jumper. What then?

My thought is I’d rather *maybe* have a way to self-jump than have literally nothing at all.

My van's battery died without warning. It was starting fine this a few days before, it sat for 3-4 days in our garage, and *poof*, it develops a dead cell and won't crank. In this case, jumper cables would have been difficult or impossible because it's a 1-car garage, the van was pulled straight in, and all the way to the wall (small garage, the only way to get the van to fit). I would have had to daisy-chain sets of jumper cables to reach another vehicle if not for the jump box.

Anyway, I still keep jumper cables in all three vehicles, but the jump boxes are much more convenient (even if not 100% foolproof).
Then again, I keep multiple ways of fixing a flat in all three vehicles too (spare tire, fix-a-flat, and a plug kit), so I'm kind of a belt and suspenders guy when it comes to that sort of thing. :)

If I were going on a trip to the back of the beyond, as I used to, I'd chance it as relatively cheap insurance. Since most of my forays these days are within range of civilization...less urgent.

But I agree...the circumstances dictate the need.

(Though it would be a bitter pill to have one that failed to work when needed...and no satisfaction from the vendor. Simply on principle...)

[rayrevolver]

Can you unplug the battery and use the NOCO, in the override mode, to see if it will work?

It is always nice to vet equipment before you need it.

I am sold on the NOCO GB40. I need 2 more.

[LittleLebowski]

I used this one (https://www.amazon.com/gp/product/B07G74CY3K/) to jump start the Tundra belonging to one of Giving Back's former coworkers. It worked, literally instantly. First time I've used it, it's sat in my Jeep for months.

[mtnbkr]

(Though it would be a bitter pill to have one that failed to work when needed...and no satisfaction from the vendor. Simply on principle...)

Agree completely, but that's life anyway. Devices like this, even from a reputable source, seldom have generous warranties. I had a Sears DieHard jumpbox, the type with the SLA battery instead of lithium, mainly for use as a field power source for my ham radio rig, but also for emergency use as intended. I used it sporadically for the radio, never jumped a car with it, and kept it charged. Shortly after the warranty expired, 1yr IIRC, the internal battery crapped out and it was useless.

That's why I never rely solely on these devices, but have them around for convenience or for the corner cases where regular cables won't work.

Thanks, I didn't see that one. The 1000 amp should be sufficient though as my two largest vehicles both have 3.xL V6 engines. Vehicle #3 is a 2l I4, I can use a 9v akaline for it. :D

Chris

[DamonL]

The one I bought came with a nice case and accessory cables. The manual said to check the battery every two months and recharge as necessary. Based on my experience leaving a Surefire flashlight in my vehicle for several years, I think the Li Ion battery will hold a usable charge longer. But it will require some maintenance. I am not getting rid of the jumper cables. It does give an option to self rescue if needed. Two is one, one is none. :) As a bonus this battery can charge cell phones and other electronics if needed.

I need to get one more and will probably see what sales are available next week for Prime Day, though these sales are tempting.

The first time I scrolled past this thread I thought, "Whoa. What are these guys jumping cars over? I didn't even know that was a thing!"

Imagine my disappointment.

[blues]

You guys wore me down. I'm going to try out the higher end Audew. With the number of power outages we get around here, having the ability to charge the iPhone without using the 4Runner will be a plus.

Hopefully it will be money well spent. (And never needed.)

The video which was linked was very helpful.

[DamonL]

What I learned from the video is larger capacity is generally more forgiving in more scenarios. I broke down and ordered one now rather than waiting.

Yep. If and when the time comes I'd probably opt for a Generac (or equivalent) liquid propane generator as I have a 500 gallon in-ground tank.

I just haven't been able to motivate myself to explore the cost, installation and electrical work required.

It would be convenient, no doubt. But I hear they need regular maintenance as well.

Their high end version is on sale as well, fwiw:

The Audew was delivered today on the amazon van. Nice piece of kit...professionally packaged with a very nice protective container.

Charging it up now. It was about 67%. After an hour it's at 89%.

If it does what it's supposed to do, I'll be very pleased. Haven't tested any of the functions as yet.

[blues]

Under two hours to fully charged...from the as delivered state.

Only have tested the flashlight so far. It works...;)

I keep one of these in the car. No idea how it compares to the others as it is the only one I have tried. Got tired of trying to keep one of the older battery style jumpers charged up and bought this after seeing one used.

Just bought the Audew 2000 amp kit
$64.21 on Prime day.

[Gater]

Thanks to folks for the helpful posts on the Audew...I picked one up on the Prime deal. I have an older lead acid unit that has a compressor, as well--it is still chugging along, but it is bulky and heavy enough that I don't always keep it in the vehicle. I have used it multiple times over the years, both in jump start and compressor modes. Adding a jumper to your kit is good insurance: in addition to the ability to self recover (either because no one is there, or because there may be an occasion where reliance on the kindness of strangers gets you involved with un-kind strangers), it lets you render assistance to others without exposing your own vehicle's electrical system to potential damage (I have helped a surprising number of co-workers in the parking lot, as well as the occasional stranger). My last effort in the work parking lot is where I became aware of the limitations of electric power steering pumps: we were able to get her car started, but the assist would cut out periodically, rendering the car (a RAV-4, IIRC) almost undriveable.

[blues]

Do any of you battery whizzes know what would be a normal rate of discharge for these jump starter batteries?

I received my 2000A / 20,000 mAH Audew (https://www.amazon.com/Audew-20000mAh-Starter-Battery-Charging/dp/B07GR17R3X) last Saturday.

Fully charged it on arrival from about 67% (as I recall) to 100% and then used it to partially charge a Fire tablet which brought it down to the mid to high 80's on charge.

Charged it back up fully and have been monitoring the charge over the past six days. It stayed at 100% on the display until this morning when it dropped to 94% upon activating the button to check the remaining charge.

Does this amount of discharge in six days reflect an acceptable rate or is there something suspect with this unit?

Thanks, fellas. I want to be sure I'm not relying on a faulty device.

[Leroy Suggs]

blues. LiPo batteries should not self discharge that fast unless there is parasitic drain.
Try discharging them down to 75% and recharging to 100% a couple of times.
Sometimes LiPo batteries need to do that to *break in*.

Thanks, brother, for the info. I'll monitor the next day or so to see if it drops further...then I'll charge one of my tablets or phone and boost it back up.

I have until Jan 31 of the coming year to return...so this will give me time to evaluate. I was skeptical to begin with about these devices, but hope to be proven wrong.


Interested in getting further replies and experience from the regulars if they are so inclined.

[whomever]

From earlier, discussing my 'gooloo' one:

"It's been sitting in the car since then, so 12 to 18 months. I just went out and checked it and it powered up and says the battery is at 99% (which seems odd, I would have expected some self-discharge). I don't have any way to actually load test it, but at least it isn't completely dead."


As a thought experiment, if yours arrived with a 67% charge, it can't be losing 6% a week unless they were pretty fast shipping it to you (I'm assuming there wouldn't be some state-of-charge dependent load on it; that would seem to be odd, but you never know).

Perhaps charge it to 100% and leave it alone until shortly before the return period is up?

My recollection is upon taking it out of the box it first lit up at 72% but immediately defaulted to 67%. Then I charged and did as you read above.

I think I'll leave it at the 96% for a day or two and see if it continues dropping...(it took six days to register the drop from 100% today)...and then I'll follow the advice about running it down some and charging it back up.

I know the rechargeable lithium batteries (16650, 18650), that I have in my dormant Malkoff flashlights register very little drop in voltage even if I don't charge them for 6 months to a year. I don't really know how much different the chemistry is between these sorts of batteries.

Appreciate the input.

[blues]

Took the advice proffered above and topped up a Kindle Fire a couple times with the unit and got the Audew down to 80% charge remaining from the 94% it started with yesterday. (I had nothing left that needed charging to bring it lower unless I'd have left it running with the flashlight on.)

Plugged it in and brought it to 100%. Checked this morning, and still 100%. (But that's how it was the first six days after charging previously.)

So, I'll check it once each morning going forward and report back when it drops below 100%. Hopefully, it will take considerably longer than six days this time.

Thanks, blues. I picked one of these up on the sale but will track your experience before unwrapping anything...I liked the idea of a compact, lightweight, and non-lead acid unit and this one looked pretty good in that test video, but it may go back if yours proves to be a clunker.

If you check your amazon account, it should be returnable through January 31, 2021. You can request a replacement or refund, either way, so you should feel comfortable using it.
But I will definitely report back on it.

In fact, Gater, if you should decide to unwrap the device, I think it would be useful for you to compare notes here. Because whether mine has parasitic draw or not, won't necessarily reflect on yours one way or the other in any case.

What do you think?...it could be worthwhile data for all of us.

For Science! I’m in...hold my beer for a sec.

Price is back up to $94.45 with current coupon offer.

68% charge out of the box. Nothing here at the moment that needs a charge, so I went ahead and stuck it on the charger.

Apples to oranges, given the lack of a compressor, but the complete kit is 2 lbs 14 oz compared to 22 lbs and change for my lead acid energizer, and probably less than 25% of the size. Should fit under a seat.

Good man. Your starting charge is virtually the same as mine was out of the box. This will be excellent info for both of us as well as the community.

I wrote Audew earlier via their customer service page to ask if my experience is normal or an anomaly.

Also:

Apparently Audew is having a sale on their own site for $67.65 (https://www.audew.com/Audew-20000mAh-Peak-1500A-Car-Jump-Starter-for-Any-Gas-Engine-or-Up-To-8-5L-Diesel-Engine-with-LCD-Power-Display-p-100058.html) for another 15 hours.

So if anyone wants in, they can still do so.

Very timely purchase. I had to jump my car today. Low battery would not crank. I think it was at 96 or 97 and was at 91 after the jump. Glad I had it.

[Gater]

Audew update: as with blues ' experience, it charged to 100% in under two hours yesterday. Checked this AM and it reads 94%. Given the spot on matches between the readings Blues and I have gotten, I suspect that the charge indicator has levels rather than a true scale; I think that is pretty typical. Not a promising start, but I think the advice from folks here to try discharging it before charging it the first time is probably on the money. I've had other devices that specify doing that, but the (scant) Audew manual doesn't mention it.

I'm going to leave it be for now and check it over the next few days.

Very interesting, Gater. As you know, I topped off a tablet a couple times Friday evening and then charged the Audew to 100% from the 80% it had dropped to. (It was at 94% before starting the two separate charging sessions of the tablet.)

Yesterday morning it still read 100%

Today it still reads 100%

It took six days at idle to get to 94% the first time...but I had initially, (first day of ownership), charged to 100%, discharged it some on a tablet, and then brought it back up to a full charge before letting it sit. So the advice above about LiPo batteries may have something to it...

I've asked JAD to chime in since he seems to be well acquainted with the technology.

[mtnbkr]

I charged my 1000A Audew when I got it as referenced in my last post. I checked it today. It's still showing 4 of 4 bars of charge (doesn't have a digital display).

So, you got the good one! ;)

[JAD]

Some quick stuff:
1) Lithium ion cells of most chemistries have a very low self-discharge rate.
2) Lithium ion batteries have some sort of a battery management system to prevent them from being unsafe through abuse (charged at too high a rate, charged below freezing, or charged after discharging to 0V).
3) The battery management system does require power all the time. A well-designed BMS has a very low quiescent current, and shouldn't drain noticeable amounts of charge in days.
4) The state of charge and state of health values reported by the BMS are an interpretation of voltage measurements through an algorithm. There are good ones and bad ones, and there are various states of the battery that can throw off SoX (not to get into it, but usually in the transition between when the battery is under load and when it's not; it can take time).
5) A lithium ion cell with a defect can drain quickly. In that case I would expect it to be a recurring phenomenon. I also wouldn't store such a battery near a basket of oily rags.
6) A defect in the BMS can drain the battery quickly. Again, I'd expect that behavior to repeat.
7) Lithium ion cells do break in, but that's typically accomplished during the manufacturing process. The effect is that capacity increases. I don't think that would explain the behavior you saw.
8) They aren't sitting at 100% SoC even if that's what the meter reads. The best way to tell is to measure the voltage across the terminals. The jumper batteries that you and I have are a big pile of cylindrical cells in parallel, so we (nor the BMS) can't tell what's going on with each individual cell, so there's some masking we'd have to math our way through.

So for Blues, I'd say there was something interesting about the SoC measurement approach that didn't like where it was, and it's now over it. I would not expect the battery to be unreliable, and if it doesn't do it again I'd ignore it.

In general, it's a good idea to find an occasional use for your jumper batteries, so that you remember to charge them every three months or so.

[blues]

Thanks, JAD, for that succinct explanation. :cool:

JAD, do you recommend the same for rechargeable lithium cells, (16650, 18650 etc), in our flashlights when dormant for months?

I've noticed that all of mine hold the bulk of their charge...only dropping from 4.2v to about 4.17 even over extensive periods.

Thanks.

Single cells and pairs have relatively simple protection circuits which are outside of my basket (the last system we commissioned had 12,480 cells each 64 Ah). However I’d expect them to use very little or no juice, and very little balancing activity — so they should do what you’ve observed. Jumper batteries are lots of cells in parallel so lots of balancing and hopefully a more complex protection approach.

[blues]

As mentioned above, I had sent an email to Audew via their website asking whether the drop in charge after six days of being idle was normal for their device...the following is their (somewhat comical) reply:

So, I think it's safe to say that I'll be making a decision on whether to return the unit to amazon before January 31. :p (But hopefully JAD's prediction is correct.)

I ended up buying a NOCO GB40 when this thread started. So far it’s jumped my Jeep at least once and my work Tahoe twice. It’s a lot easier than using jumper cables.

[Leroy Suggs]

My Audew 2000 came today.
It was 71% out of the box.
Charged to 100% in 2 hours.

I hooked up an iPhone 7 and an iPhone 11 that were at around 30% charged and charged them to 100%.
The Audew showed 62%. Charged it back to 100% and will check the charge in a few days.

[blues]

Update:

The pattern holds. Six or seven days from charging the unit from 80% back to 100% and checking it once each morning, it's back at 94%.

This does not inspire confidence (in me) and I will most likely return for refund as opposed to an exchange.

I may hold on to it for a while before returning to see how it progresses from here, (since I have the ability to return by end of January, 2021), but not sure I will.

[whomever]

That sounds defective, I'd swap for a new one.


I'm not an electron head, this is a paraphrase a friend gave me when trouble shooting a short-battery-life issue, with apologies if it is garbled:

"Devices without a mechanical switch all have some kind of circuit that acts as the switch. That circuit necessarily uses some current. In a well designed, non defective circuit, that parasitic draw will be minuscule, maybe using a couple per cent of the battery in a year or some such. But that circuit will be built of various components - resistors, capacitors, and so on, If they are out of spec, sometimes even a little bit, the parasitic draw can go way up."

I don't think most manufacturers of consumer grade stuff test for parasitic draw. My friend sampled several of the devices he was working with and got something like a 10X diff in parasitic draw.

(a few years back, when LED flashlights were changing over from hard mechanical switches to soft switches, so they can be multimode and all, I think several manufacturers had QC probs resulting in high parasitic draw. I bet it's hard to design a low draw circuit, and harder to design one that is low draw across a range of component variance)

[Leroy Suggs]

Mine is at four days holding 100%. I will check in four or five more days and if is holding I will call it good and put it away in the SUV.

[Gater]

Mine's still sitting at 94%.

[blues]

Mine's still sitting at 94%.

If I haven't returned it, Gater, I'll check mine in a week and see if it's holding at 94%. I wonder if that's the "default" increment it drops down to from 100% once it has experienced some minor threshold of discharge. (I'm a bit leery, and the email I got back from China did little to boost my confidence.)

I knew this was a bad idea...;)

[Leroy Suggs]

My main concern is the made in China LiPo battery.

[boing]

Can these things typically be left hooked up to a 12v outlet in the vehicle so it’s charging whenever you’re driving?

If the vehicle sits long enough for the car battery to run down, would this deplete the charger as well if it’s hooked up to a 12v outlet?

[boing]

My main concern is the made in China LiPo battery.

I’d be curious to cut one open and see if they’re actually using a stack of reputable cells from Samsung or something.

Six to seven days was where mine dropped to 94%. You might want to give it another day...and definitely don't forget about it. They recommend charging it every three months if not used.

I'm monitoring to see if and when mine drops from 94%.

[Leroy Suggs]

Good advice. Thanks brother.

[boing]

I have 2 coming. I’ll test them both weekly for awhile to see how they hold up, then monthly. It would be convenient if they could reliably last 6 months and I could put charging them on the same maintenance schedule as the fuel swap for the generator.

I wonder how well they will hold a charge in storage during the hot summer months as opposed to winter.

[JAD]

They should be pretty indifferent to temperature in terms of self discharge.

Does the fact that the Audew dropped down to 94% after six days of no usage, (again), give you any additional thoughts on the viability of the unit?

I'm testing now, (without charging back up), to see if and when it drops from 94%, and what the next level down might be if it does.

[LittleLebowski]

I wouldn’t worry about it. I never tested mine for months until it had to jump start a dead Tundra and it worked instantly. I suppose I should charge it...

[JAD]

I don’t know what SoC it takes to do the job, particularly on a cold day. That would be worth figuring out.

Bought the above on Aug 25, 2020 when it was on a bit of a sale. Used it last week to charge 2 phones based on this thread to work it down before charging it back up.

Used it to charge a super dead 04 CRV with a 100 month Honda battery in it ( I am going to presume that it is batt # 2 for the car).

Had to go to manual override and it turned right over.

So much easier than maneuvering a 2nd car with jumper cables.

Looks like you may be good to go, bro'.

Mine is on day six at 94%. (It had dropped to 94% after six or seven days (being unused) from 100%.)

If it stays at 94% for another couple of weeks, I may be inclined to live with it. If it drops again, I'll probably request refund or replacement.

Hey blues

Still sitting at 94%...no change since that initial drop off. I may take it back to 100% and see what happens for another week before I decide if I'm keeping this one. We're starting to get some colder mornings, which is a good reminder of potential battery problems.

[blues]

Thanks, Gater

Mine is still sitting at 94% which is somewhat encouraging as it's been slightly longer than the period of time it took to drop to 94% from 100%.

I'm going to monitor it without a recharge for a few more weeks to see if it drops further...and then I'll at least recharge before the end of January to make sure it can be recharged and also power up a couple of small devices.

I don't have a vehicle to test it on unless I come upon one by happenstance.

[Joshmill]

I took mine out of the car to let a friend charge her phone with it. Mine was at 94% as well after riding in there for a couple weeks.

Received my Audew 2000 approx. 7 days ago, came @ 74%, charged it until 100%, in my POV for the last 7 unused & checked just now still showing @ 100%.

Yes quoting myself as the Audew was checked again today, still @ 100% & unused in my POV & 11/11 will be 1 month since I received it.

[boing]

I bought two Audew 2000s a week ago and just checked them. One has dropped to 94%, the other one is still at 100%.

I noticed when charging them that one came out of the box with a little lower percentage on the meter than the other. I plugged them both in at the same time, and the lower one charged faster than the higher one. Also, the initially higher one sat at 99% for quite awhile before finally topping out at 100%.

I wish I had kept track of which was which when I put them in the vehicles.

I wonder if the drop to 94% is misleading. Maybe the accuracy of the capacity reading would benefit from a full discharge/charge cycle to “calibrate” the meter.

[blues]

boing

It seems like the 94% reading is the next step down from 100% during any amount of self-discharge. In other words, it doesn't go 99-98-97-96-95-94.

If it holds at 94% for weeks on end, then powers some phones or tablets and then accepts a charge up back to 100%, I'll be a lot more confident that the 94% reading is a trivial matter and of little concern...based upon what our other forum members are experiencing thus far.

Time will tell. Glad to have until the end of January to conduct this "experiment".

Thanks Gater. It took six to seven days to drop to 94%. Mine has now been at 94% for ten days following the drop.

[JAD]

I bought two Audew 2000s a week ago and just checked them. One has dropped to 94%, the other one is still at 100%.

I noticed when charging them that one came out of the box with a little lower percentage on the meter than the other. I plugged them both in at the same time, and the lower one charged faster than the higher one. Also, the initially higher one sat at 99% for quite awhile before finally topping out at 100%.

I wish I had kept track of which was which when I put them in the vehicles.

I wonder if the drop to 94% is misleading. Maybe the accuracy of the capacity reading would benefit from a full discharge/charge cycle to “calibrate” the meter.

Your first phenomenon is very normal. LIBs charge very slowly at the top and bottom ends, like by an order of magnitude.

I am certain that 94% is an artifact and would not worry about it at all. Call it full and drive on, literally.

It's good to have you in this discussion JAD as most of us don't know what we don't know...even if we have used various lithium type batteries in our devices for some years now.

Again, I would yield to anyone who jacks with small packs more than me, like NH Shooter. Also, for intellectual property reasons I can't talk too much about state of charge algorithms except to say that there's a lot of art mixed in with the science, and people overestimate the importance of SoC (rather than voltage, which is what we should care about) because it's an easy metric to comprehend.

Two weeks today @94% without dropping further. Continuing to monitor, but this is somewhat reassuring.

(Dropped to 94% from 100% after six or seven days laying idle following a full charge up.)

You guys got me curious about my GB40. Going back to page 3, I charged it in early August. On 6 Sep I used it to jump start a Hyundai Sonata, so a little 4-banger motor. It has sat ever since.

I checked today and it was showing "Green" which means between 76%-100, I believe. It has only 4 lights for the battery, 25%, 50%, 75% and 100%.

So its holding a reasonable charge after 1 use and sitting about 3 months. I am topping it off tonight.

[Gater]

Checked mine today, and it dropped to 94%, which seems to mirror blues experience (I recharged it to 100% Monday). If it sits steady there as Blues' unit has, probably no big deal. I'll give it another week.

[boing]

I don’t suppose there’s a way to test these as actual jump starters without intentionally running down the car battery, and potentially trashing it in the process.

[Joshmill]

I don’t suppose there’s a way to test these as actual jump starters without intentionally running down the car battery, and potentially trashing it in the process.

You could just disconnect your battery and try it out direct. Just don't let it run too much for the alternator to try to charge it. You'll have to reprogram your radio presets afterward but you'll get the idea. A better idea would be to try it out on your neighbor's car.

I replaced my car battery a month ago when I had to ask for a jump at work but luckily I keep a set of jumper cables in the trunk. Since it's a new battery I don't see myself needing to use it this winter but it's nice to have the option of using the jump pack as a power bank in an emergency or helping others without needing to pull along side them.

The "junior" was the version I had for close to 25 years. When I replaced it, I went with the "plus".

That makes sense:
BT Jr - 0.75A, $24.98
BT Plus - 1.25A, $49.95

The NOCO Genius 1 splits the difference at 1.0A, $29.95

These are Amazon prices, so maybe there are better deals other places.

Here is the Black&Decker Unit I had:
https://www.amazon.com/BLACK-DECKER-BM3B-Automatic-Maintainer/dp/B0051D3MP6

Says it charges at 1.5A and is $20.18. It is very lightweight, especially compared to the BT Jr. It worked although I could have swore it was slower to top off than BT Jr. Amazon says I bought this in 2014 and I dropped it last year, so worked for most of 6 years. Not gonna get one again.

For now I can move the Jr around, especially in the winter with the mower, RV battery, and a car in the garage.

Got an opportunity to test my TopVision jumper for the first time today. Guy in a GMC quarter ton pickup a few spots down at home depot had a dead battery and asked for a jump. Told him I had something easier than cables, hooked it up (which was slightly difficult because GM chose to mount the battery in the back of the engine compartment and these have short connector cables). Nevertheless it cranked the engine over with ease. Didn't even budge the display off 100% reading. Nice to get some real world proof it works.

Does anyone have any input about Antigravity Batteries' Micro-Start series?

In particular, I'm looking at the XP-1: https://antigravitybatteries.com/products/micro-starts/xp-1/

I like that they have various sizes in the nylon or leatherette hardcases in various dimensions, which gives us the ability to match it to a particular space. Since this one is flat, I'm thinking I could velcro it to the engine wall behind the seats in my Cayman. I can't put it in the frunk or trunk, because those compartments are opened via a battery actuated mechanism which first has to be jumped from the cabin before you can access the battery compartment.

And today it saved me a bunch of hassle and drama.

On my Subaru, I leave the headlights on auto. They stay on until I remove the ignition key. If I turn off the engine, but leave the key in the switch, the headlights are still on. Like today when I went through the McDonalds drive thru and ate in the parking lot. :( When I went to leave, I got the dreaded click. I slapped my fore head because my brother had told me that could happen.

I got out, popped the trunk and hood, hooked this thing up and within 5 minutes I was on my way.

It was still at 100% before I jumped the car and was at 82% afterward. I'm charging it to full and ordering a couple more for the other cars.

And today it saved me a bunch of hassle and drama.

On my Subaru, I leave the headlights on auto. They stay on until I remove the ignition key. If I turn off the engine, but leave the key in the switch, the headlights are still on. Like today when I went through the McDonalds drive thru and ate in the parking lot. :( When I went to leave, I got the dreaded click. I slapped my fore head because my brother had told me that could happen.

You said it. Besides I was angle parked with my front against a fence, the car to my left was a lady who had pulled off the Interstate and was sleeping, to my right a carload had gone inside to eat, plus I didn't have any jumper cables. :)

NOCO GB40. I *think* I charged it 11/2020. Not sure though. Checked it today and 3 bars... so between 50-74%.

This is an older thread but, given the amazon deals going on right now, are there any updates to these recommendations? Anybody have a recommendation for a combination jump pack/compressor? Thanks.

Just ordered this. Under $50 with prime day and coupon. Worth a try.

Thanks. It looks as good as any of them. The only thing I can't tell with this or most of the others I've looked at is if it has a manual override function.

A little pricey, but if you have Ryobi tools this is good:

I have one, and like that I can just swap out that battery every few months, rather than bringing it in to charge, and possibly forgetting to put it back in the car.

That Ryobi looks really handy. I went to Milwaukee about a year ago for tools, but I like that setup a lot. I ended up going with this one: https://www.amazon.com/dp/B0D41NT5KL?ref_=ppx_hzod_title_dt_b_fed_asin_title _0_0. Not a bad price with the discount and the coupon, it says it has the force start option and out of 130 reviews, 95% are five star. I got one for me and one for my daughter so I hope it's decent.

I want to bite down on one of these, particularly at this price but I need to do some research and see if it will work in my new Transit, both for starting and inflating.

Be careful buying inexpensive battery bombs

If one goes to a car dealership one would be hard pressed to find a lithium jumper that wasn't a NOCO. Like 5yo ones that are still cooking that are used almost every day by techs.

There are a number of lead-acid ones that are ok

Not the best place to save a hundy

I bought the NOCO one LittleLebowski recommended, and I've already used it twice last winter on the neighbors. Worked like a charm.

The neighbors' cars, not the neighbors themselves.
