Like every solar panel, the Sunnybag SUNBOOSTER works best when it is inclined at a 90° angle to the sun. If the solar panel is positioned in full sunlight, it will charge a smartphone within 2 to 3 hours depending on the model. Larger devices, such as drones or tablets, take about 6 to 8 hours. In cloudy weather or when the orientation towards the sun is not optimal, the charging times increase accordingly. Of course you can also use your SUNBOOSTER to charge power banks in order to store the power of the sun for later use.
Even cold and wet weather cannot harm the robust scratch-resistant surface. So you can also use the solar charger in winter and in wet conditions. The eyelets on the corners of the panel make it easy to attach the SUNBOOSTER to various objects such as backpacks, tents or trees.
