Out here in the PNW, grid power is unreliable enough that a lot of people have portable generators. Many even have fixed home gensets

And this isn't even for disasters so much as just routine seasonal storms. Half my city had no power for 12+ hours after high wind this week

So I don't see backup power as disaster prep. I file it with snow shovels and lawnmowers as a "everybody needs / probably already has one"

Also, srs Q: what would you use a single car battery + inverter for? Can't cook / run a fridge for long. Barely 4 hours of a TV or lamp

Amateur astronomers often run telescope gear off them over the night but that battery type even kind of sucks for that despite popularity

Deep cycle marine batteries handle those sort of slow draw repeated discharge cycles better. Better longevity, avoid plate sulfination, etc.

Another clumsy thing about the branded & packages car starter type batteries for astro use is dumb high resistance connectors.

Yeah I think deep cycle is obviously a requirement for this case. You can get deep cycle car batteries - my intention to imply that

Also nothing wrong with a big bank of deep cycle batteries. But once they're drained that's it unless you have solar or something

Which is cheap to have, and solar is actually already on most lists I've seen.

My next move I’m thinking of suitability for solar as a nice to have.

Very regionally dependent. Most power outages in the PNW are during the winter, heavy cloud cover so not that useful
