Abstract
A wireless charging unit for a mobile device unit. The wireless charging unit may include an interface surface for the mobile device unit to be positioned upon, and a power transmitter device configured to transmit power wirelessly to the mobile device unit when the mobile device unit is positioned upon the interface surface to charge the mobile device unit. A switch may be electrically coupled to a power connector plug and configured to disable reception of power by the power connector plug from a power outlet in response to a sensor circuit detecting that the mobile device unit has been removed from the interface surface to a distance.
