Don't know how much you've looked at these Phil.
Almost without exception, they provide USB "phone" charging and other
low-current (compared to car-starting) outputs.
They're not optimized for running a rig (or a laptop or a phone) but
they do have a stack of lithium cells and some protective circuitry for
a very attractive price.
I agree that I wouldn't use one as a backup power in commercial service,
but for what I need they seem to work well.
Sometimes perfect is the enemy of good-enough.

Don't be misled by the A-Hr ratings. Battery construction for
short-term high-amperage discharge (such as car starting) is radically
different from that for long-duration low-amperage loads such as
proposed. Ditto for deep-discharge and float charge capabilities as
well as battery chemistry.
