1. A mobile device capable of transferring power to a destination device, the mobile device comprising:
- a power storage module that stores power;
an initiation module configured to receive initiation information, the initiation information including at least one parameter associated with the destination device;
a power transmitter module configured to wirelessly transmit power to the destination device, the power transmitter module including;
a coil module configured to transmit a power transfer signal to the destination device; and
a load module configured to load the coil module with the power transfer signal;
a sensor module configured to sense an amount of power transmitted to the destination device based at least on an amount of power change that has occurred within the power storage module during the power transmission; and
a controller module configured to control the power transmitter module based on the at least one parameter and the amount of power transmitted to the destination device that is sensed by the sensor module.

Abstract
A mobile device is disclosed that is not only capable of wirelessly receiving power from a source device, but also of wirelessly transmitting power to a destination device. The device includes one or more power modules and corresponding coils for transmitting/receiving signals from which power can be loaded/extracted. In addition, the device can receiving initiation information identifying power transfer standards supported by each of the source and destination devices, and can control its one or more power modules to operate in accordance with the standards identified in the initiation information.
