I took a look around and a lot of comments mentioned to get one that uses ‘LiFePO4 Batteries’, and that seemed like a reasonable requirement.
They’re supposed to have a longer life span, be safer, light weight, and better charge/discharge efficiency which is in line with what I’d be looking for.
Some brands/models that I saw recommended:

I’ve been pleased with my Ecoflow River 2 Pro for the brief time I’ve owned it. I’ve been using it as a UPS for my CPAP, and I’m planning on taking it camping once it stops being so cold. I can get about 2 full nights of use out of it if I use all the comfort features my CPAP has, or probably a week+ if I turn off those things (e.g. the humidifier).
