Note: This solar panel charger doesNOTstore power. You will need a power bank to store power or connect directly to your device to charge. Important Note: Please DO NOT lay the solar panel directly on CONCRETE, SAND, ROCK or other highly conductive surfaces in direct sunlight. This will cause the solar panel to overheat and significantly reduce the conversion rate and output wattage. High-Speed charging Delivers the fastest possible charging speed, up to 2.4 amps per port amps overall under direct sunlight. 21-watt SunPower solar array is 21.5-23.5% efficient, providing enough power to charge two devices simultaneously. Works in wind and rain Premium PET panels and high-wear water-resistant polyester canvas can handle all sorts of challenging outdoor conditions. Portable The compact solar charger (11.8 x 5.9 inches, or 25.2 x 11.8 inches when turned on) and the backpack cord can be easily attached to your backpack. Lightweight (18.9 ounces) and ultra-thin design (0.6-inch closed or 0.1-inch opening) makes it ideal for long-distance adventures.

Tips For Optimal Use: The charge your device gets depends on the amount of sunlight falling on the panels. While the polyester canvas provides some water protection, we recommend minimizing moisture exposure to protect the electrical components.
