Find the perfect 1U 10" Mini Rack UPS

...since one doesn't exist, maybe someone should _make_ one!

The space constraint is real, but you could definitely build a UPS with one or two AC outlets on the back, supplying something like 60-140W of total power, with an integrated Li-Ion battery—and still have enough room for decent power filtering.

Right now, the three commercial products I've seen that _might_ fit the bill are:

- [ZeroKor Portable Power Bank with AC Outlet - 65W / 24 Ah](https://amzn.to/3ZIQk0z) - $57
- [Goal Zero Sherpa 100AC - 100W / 25.6 Ah](https://amzn.to/4giTP4V) - $177
- [Krisdonia AC Outlet Portable Charger - 130W / 60 Ah](https://amzn.to/49KOdOp) - $229

I really would like an AC UPS, because that'd be compatible with most anything... _however_, if you have an adequate PoE switch, maybe a 12V/19V/24V DC UPS would be adequate, with just a barrel-jack output (or multiple barrel jack outputs...?).

The trouble is, some people will build racks with USB-C powered devices. Some will build racks entirely powered by PoE, and yet others will require AC adapters... so being able to serve everything would be ideal.

I've ordered the ZeroKor, since the price is right, and I intend to see if it'll fit at the bottom of my RackMate T0 and serve power to my PoE-powered Pi rack setup, which consumes 17W at idle, and probably 40-50W max.

The issue names no repository files, tests, or implementation entry point. Start by reviewing the discussion and the listed UPS constraints and candidate products; done would require an agreed hardware scope and a documented design or implementation path.
