What do you think about power stations?

I’ve been thinking of getting one but my main use case is powering the fiber modem and it will be living in the garage mostly. Are there any that handle decent temperature swings? I know batteries hate that sort of thing.

What if I put it in a fridge that is also powered by it?

I got a cheap UPS for this. They’re designed more for this purpose. My fiber modem takes FOREVER to reconnect so it’s moreso for little power dips in my case.
I was thinking of that but it gets both colder and hotter than most UPSes can handle in my garage.
Probably, but they’re likely cheaper per watt hour than the style in the photo.
