It features 2 cradles that charge your controllers via their EXT ports and 2 indicator lights that display a red controller icon when charging and a blue controller icon when fully charged. Plug the included 3 ft. Micro cable into the Micro port on the back of the TwinVolt and the other end into a 5V 1A USB power source (not included). Charge up and move out, soldier!
