Claim:
1. A power system capable of transferring power to a portable device separable from the power system, the power system comprising: a power supply for electrical connection to a mains voltage and adapted to convert the mains voltage into a DC voltage; and a wireless power unit electrically coupled to the power supply DC voltage, the wireless power unit being operable in a low-power detection mode to detect an object in proximity to the wireless power unit, the wireless power unit being further operable in a power supply mode to provide wireless power to an object in proximity to the wireless power unit, wherein the power supply is adapted to interrupt the conversion of the mains voltage into the DC voltage during operation of the wireless power unit in the low-power detection mode, the power supply being further adapted to resume the conversion of the mains voltage into the DC voltage during operation of the wireless power unit in the power supply mode.
