How does the SWISSTEN foldable solar panel work? It's simple. You can fold it up and store it in your backpack or car.

User rating

I like to go outdoors, sleeping under a tent or under a tent and enjoying the peace without people. But I can't do without my navigation, mobile phone and camera. So I always have to figure out where to recharge them. The SWISSTEN foldable solar panel is a great help - if the light conditions are ideal, it charges absolutely wonderfully.
