Abstract

A wireless input device is provided. The wireless input device includes a rechargeable wireless mouse, a wireless receiver and a charging pad. The charging pad includes a wireless power transmitting module and a charging control circuit. The charging control circuit is electrically connected to the wireless power transmitting module. The charging control circuit correspondingly activates the wireless power transmitting module to wirelessly output the electromagnetic power according to an activation signal provided by the wireless receiver. The charging pad receives the activation signal when the wireless receiver is connected to the charging pad. When the charging pad is not connected to the wireless receiver, the charging control circuit stops the wireless power transmitting module from wirelessly outputting the electromagnetic power. Accordingly, the charging pad of the present invention can avoid damage resulting from the abnormal charging so as to save power.
