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 recently went through a 8 day power outage from hurricane Milton.

    I bought an Anker f2000. It retails new for ~$2000. Even that can only power my fridge for maybe 23 hours.

    I don’t own one, but I might recommend these coolers from Anker instead. I’d buy one if I had the space. link to refurbished unit

    It last 42 hours on battery, can be charged via the car or solar, goes down to freezer temps, and the battery is detachable and can be used to charge your devices. It would be much easier to keep essentials cold for a week using this, even if it’s small, and it would be great for car camping.
