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

    I don’t have a specific brand offhand, but if you’re in the US I would recommend reaching out to your local amateur radio club and specifically the ARES group. These are the folks who respond during a natural disaster and set up emergency communications. If you can wait for about 6 months, you could go to Field Day in June.

      specifically the ARES group

      Cool, it looks like it operates up here in Canada as well, thanks for sharing! I’ll check them out sometime

        Great! When you’re setting up emergency communications for 1,000 people who are without power for days to weeks, you want to make sure your battery packs are going to work reliably.
