Abstract
Provided is a combination of a receiver unit and a mobile device and/or battery, the device and/or battery capable of being inductively powered and/or charged by the receiver unit, the unit being a component of or electrically connected to the mobile device or battery. The receiver unit comprises a receiver coil and a communication and control system. The receiver coil generally has a planar surface, and the receiver unit is capable of receiving energy from a base unit via an inductive magnetic field and using the energy to power and/or charge the mobile device or batter. The communication and control system in the receiver unit regulates an appropriate power, voltage and/or current value of an output of the receiver unit to charge or power the mobile device or battery.
