4.1/5
A low-cost, light LiFePO4 station for weekend camping and short outages that tested as efficient as far pricier rivals. Skip it if you need more than two AC outlets or fast solar charging.

Pros
- Tested at 85% efficiency, on par with pricier brands
- Full wall recharge in under two hours
- Under 18 lb for 768 Wh, light enough to carry one-handed
- 15 ms switchover keeps a router or CPAP running in an outage
Cons
- Only two AC outlets
- Solar input tops out at 200W, so a full solar recharge takes most of a day
- Reviewers noted inconsistent fan behavior and a faint high-pitched sound
- Measured idle draw of about 14W drains a stored charge in roughly two days if left on
How it scores
The rating comes from 8 measured or published factors, each scored 0-100 against fixed reference points for its size. How we rank explains each one.
Independent capacity tests
Usable energy delivered from a full charge through the AC outlets, as measured by independent reviewers. Inverter losses mean no station delivers its full rated capacity.

#18 in Mid-sizeFull review
A low-cost expandable LiFePO4 station for home backup at moderate loads. Testing suggests it struggles near its rated 1,800W, so keep heavy loads well below that.

#20 in Mid-sizeFull review
A high-output LiFePO4 station for running power-hungry appliances in short bursts and fast UPS backup. Buy a larger battery if runtime matters more than wattage.
