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 have several Ecoflow batteries. Delta, River Pro, and River 3.

    No complaints. I’ve used them in power outages. The delta is large enough to power an oil filled heater, and any of them can keep my fridge and network appliances running.

    I’ve since gotten solar, but I still keep the portable ones around. The River 3 acts as a UPS and emergency power for my CPAP machine, and the others are still an extra 2kW for whatever I might need.

    Asan aside, they also work great for monitoring device power use in lieu of something like a kill-a-watt. I’ve used them intermittently to confirm power draws on devices in my house in order to optimize my power consumption for my solar setup and find inefficiencies in my home.
