Abstract
Inductive wireless charging for mobile devices are described that utilize resonant inductive coupling between a wireless inductive charging device and the battery of the mobile device. The power transfer from the charging device to the mobile device is adjustable. Signals are sent between the devices to determine power transfer efficiency and to adjust settings to approach or achieve a desired target efficiency.
