Yes and no.
Yes the Kobalt is a ‘thing’ you grab from the trunk when needed. Yes the air and power cords are coils up inside, adding bulk. Yes it has handles built in to grab it with, adding girth. Yes the pump is enclosed, but against that it is more or less rectangular in shape, and fits easily into a shelf or area without getting squashed.
The Viar was always like wrestling an eel; all the cords are loose and aren’t ‘in’ anything, iIRC I stored it in a box anyway.
They aren’t really that $$$ so you might just pick one. They both worked well and did the job, it’s probably just personal preference at the $50 price point.
