Description
The ALLPOWERS SF400 400W Flexible is a flexible solar panel of 400 W. It charges a portable power station from the sun, for genuine off-grid autonomy.
How much useful solar power in a day?
Rated at 400 W, in good sun it harvests a meaningful share of that each hour. Over a clear day that is enough to seriously offset, or fully cover, a station's daily use in a van or at camp.
Flexible and light: weight and setup
The flexible build hugs a curved van roof and stays low-profile, ideal for a permanent fix. Weatherproofing is rated 68.0.
Works with your station or battery
It connects to the usual portable power stations (EcoFlow, ALLPOWERS, AFERIY and others) through standard solar connectors. Check the connector and the voltage window of your station before buying.
Choosing the right panel for your use
Match the panel to your station's solar input and to how you travel: a foldable panel for flexible camp setups, a flexible panel for a permanent van-roof fix, a rigid set for maximum harvest at a fixed spot.
