Oh yeah, that's for a computer or maybe a room. The generators people put in their garages or crawl space are usually gasoline powered and run the whole house. I think its cheaper than putting in a wall of batteries, but idk

Noo, you can get consumer products for around 100-200 bucks.
Something like this (no buying advice)
Yeah, those go under the desk... Right? I don't think that'll power a house for long.

Yes, these devices are small and just meant to keep a computer up for maybe 10 minutes. Could be longer with a raspberry pi. They can send a shutdown signal though, so they can at least properly shut down computers before they run out of juice.
