Overview
Powering a phone, camp light or CPAP from a pure sine wave AC outlet, this compact power station stores energy in a LiFePO4 battery. It accepts solar charging through an MPPT controller and includes a car charger cable.
Clean AC output, fast USB-C charging and solar input are the reason to look, in a small body. The runtime field says fifteen hundred hours, which cannot be right for this capacity.
Who it's for
A traveler or homeowner who wants quiet backup power for phones, lights and low-draw medical devices. A buyer with devices above the output limit should look at a larger station.
Pros and cons
- Pure sine wave AC output
- Solar input with MPPT
- Light for its capacity
- Output limit rules out big appliances
- Runtime figure is a listing error
- Only two outlets
Performance notes
Capacity in watt-hours sets how long a device can run, so a small load lasts many hours and a load near the limit drains the unit quickly. Clean sine-wave power suits sensitive electronics, and the battery management system guards against overload and heat. An MPPT controller extracts more power from a solar panel as light changes.
