Qi (pronounced as "chee") charging is an optimized inductive charging concept also known as “wireless charging,” allowing you to charge your devices wirelessly. Compatible devices’ batteries are charged by using induction transfer without requiring separate chargers, cables or adapters... Simply place your compatible device on top of the wireless pad and watch your device charge. Finally--an end to cords!
