A device for charging a battery unit of a mobile telephone handset includes an electric field generating unit for generating an electric field, and a charging current generating unit adapted to be disposed on the mobile telephone handset. The charging current generating unit includes a sensing coil for sensing the electric field from the electric field generating unit and for generating a current signal corresponding to the electric field sensed thereby, and a current processing circuit, coupled electrically to the sensing coil, for receiving and processing the current signal so as to result in a charging current that is adapted to charge the battery unit of the mobile telephone handset.
