"There are two components to the uBeam charge system
: the uBeam Charge Station, which plugs into the wall and emits energy, and the uBeam Battery Adapter, which plugs into your electronics and absorbs energy. The uBeam Battery Adapter consists of a conglomeration of energy harvesting transducers connected to a rechargeable battery, where the beamed energy is stored. Once the uBeam Battery Adapter is plugged into your electronics, it will start charging your device. With a USB adapter on one side of the battery, and a PC or Mac power adapter on the other- uBeam can charge many portable electronics simultaneously."
