It is composed of three solar panels of about 20x10 cm interconnected by a foldable fabric support and which can be easily orient towards the sun. Then just wait for the loading, relatively fast but of course depends on the quality of the sunshine by definition random and uneven across regions and seasons.
The use of this sun charger is obviously a priority that of hiking or outdoor trail, when one is surrounded by nature and away from everything. The product has also carved out a look for adventure with its four green carabiners to hang it in a good position, by one or more of its 4 attachment points, a backpack or a belt.
