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:

  • BLUETTI came up in more recent posts
  • Ecoflow (specifically the RIVER 2) came up a lot
  • Anker was suggested a few times, but the comments weren’t that detailed

edit, added an image of what I’m referring to

  • bluGill@fedia.io

    Second this. I was at camp (with my kids) this summer and able to keep my phone charged just by leaving my power bank charging at the tent while I was hiking. No more trying to find a free outlet in the dining hall, just recharge while sleeping. My power bank would have made maybe 3 days, but I was able to be gone for the whole week.

    We got green bonus points at the camp inspections because I had that outside my tent as well.
