A wireless power-supplying mouse pad with an apparatus-identifying function is applied to a wirelessly-charged apparatus. The wirelessly-charged apparatus includes an inductive identification tag. The wireless power-supplying mouse pad includes a mouse pad body, an inductive charging unit and a control unit. The inductive charging unit includes a tag identifier. The tag identifier identifies the inductive identification tag of the wirelessly-charged apparatus to obtain an identification signal. After the tag identifier obtains the identification signal, the tag identifier sends the identification signal to the control unit. After the control unit receives the identification signal, the control unit controls an emitting power of the inductive charging unit based on the identification signal.
