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:
BLUETTIcame up in more recent postsEcoflow(specifically theRIVER 2) came up a lotAnkerwas suggested a few times, but the comments weren’t that detailed
edit, added an image of what I’m referring to
I don’t have a recommendation but thank you for not calling them a “solar generator”
In addition to whatever power bank(s) you end up buying, you might consider getting a portable solar charger. I’ve used mine in like 3 different power outages, either because the outages were extended or my power banks had slowly lost charge over the winter.
I got one with like four charging ports which was nice because I could charge my phone and recharge my power banks and USB lantern at the same time.
