1. An apparatus for wirelessly transferring power, comprising:
- a wireless power transmitter configured to wirelessly transmit power at a level sufficient to power or charge a first device positioned within a charging region; and
a controller configured to;
determine a first amount of power, wherein the first amount of power is an amount of power transmitted by the wireless power transmitter; and
determine a second amount of power, wherein the second amount of power is an amount of power received by the first device when positioned within the charging region, the wireless power transmitter configured to reduce power transmission in response to determining unaccounted power based on a difference between the first amount of power and the second amount of power.
