The Sandberg Foldable Solar Charger is a highly efficient solar panel that converts sunlight into electricity. It features two USB outputs that can be used to charge your USB devices, such as smartphones, tablets, or power banks. By connecting it to a power bank, you can store electricity for later charging of your smartphone or use it as a stabilizing intermediary while charging, provided your power bank supports simultaneous power input and output. The USB outputs are located in a convenient zippered pouch with enough space for your USB device. The included carabiners can be used, for example, to attach the solar panel to your backpack when you head out on an adventure.
