RAVPower RP-PC118 Prime

The high-efficiency solar cells from Ravpower convert up to 21.5-23.5% of sunlight into free energy. Charge up to two USB devices simultaneously and forget what it feels like to search for an outlet. Important note: Please do not place the solar panel directly on concrete, sand, rocks, or other highly heat-conductive surfaces in direct sunlight - this will cause the solar panel to overheat and significantly reduce the conversion rate and output power.
