Make best use of the sun and use the BioLite SolarPanel 5+, a highly efficient solar module, to power your adventure.
It's only 2,4 cm think and weighs 390 gramm so you can easily carry it in your backpack to wherever you go. When the sun shines, the integrated 2200mAh battery is loading, so once the sun hides behind a cloud you can use the loaded battery. At maximum sunshine it provides 5 Watt that can be tapped into via USB cable. If the weather is too bad and you have another energy source at hand, you can charge the SolarPanel 5+ battery via micro USB port.
To make sure you get the best energy from the sunshine, take a look at the integrated sun dial. When you see a shade there, rearrange the 360° stand of SolarPanel 5+.
The splashproof module measures 257 x 208 x 24 mm.
