Our verdict

The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.

Best for: Budget campers who just need to keep phones, cameras and a laptop alive.

What we like
  • Under $200 with LiFePO4
  • 60-minute full recharge
  • 7.7 lb
Where it falls short
  • 300W output runs devices only
  • 256Wh is a single evening of real use
