High Energy Conversion: Highly efficient solar cells convert up to 21.5-23.5% of solar power into free energy. Charge up to two USB devices simultaneously and forget what it feels like to have to look for a socket
COMPACT SIZE: One of the most compact solar chargers on the market. Benefit from free solar energy in a lightweight foldable format you can always carry with you no matter where you go.
CHARGE SMARTER: iSmart technology automatically adjusts to connected devices and provides the optimal charging current to minimize charging time.
SMART IC: Smart IC frequency technology detects all connected devices' input and distributes current output accordingly for up to 3.2A.
Important Note: Please DO NOT lay the solar panel directly on CONCRETE, SAND, ROCK or other high heat conduction surfaces in direct sunlight - this will cause the solar panel to overheat and significantly reduce the conversion rate and output wattage
