A wireless device charger is configured to produce an alternating magnetic field, thereby inducing an alternating electrical current within a capture coil of a personal electronic device proximate to the wireless device charger. The wireless device charger includes a source coil having a ferrite element configured to generate the alternating magnetic field, a housing formed of a thermally conductive material in thermal communication with the ferrite element, and an air movement device configured to produce a turbulent air flow across a surface of the housing flowing from an air inlet to an air outlet, thereby reducing a housing temperature.
