Abstract

A wireless battery charger comprises of a housing, a processing module, and a rechargeable battery. The housing has a socket, at least one terminal mounted on at least one inner wall of the socket, a first display unit, and a second display unit. The processing module mounted in the housing has a printed circuit board electrically connected to the terminal, at least one connector mounted on the printed circuit board and corresponding to an outer periphery of the housing, a switch, a power indicator corresponding to the first display unit, a charging indicator corresponding to the second display unit, and a plurality of electronic components. The rechargeable battery is received in the housing and electrically connected to the printed circuit board. The rechargeable battery can be fully pre-charged prior to taking the wireless battery charger outdoors for immediately charging a rechargeable battery used in a portable electronic appliance.

Claims
