A wireless battery charger via carrier frequency signal for devices with batteries where it is not convenient to run electrical wires or place the device in a charger for charging batteries and for portable devices that can benefit from either partial or full battery recharge without connecting to a hard wired charger comprising:

  • means for generating and transmitting a signal of a predetermined power and carrier frequency, said signal capable of being modulated, said modulation being one of frequency modulation, amplitude modulation and phase modulation;

    means for receiving the transmitted power signal;

    an energy storing circuit, for storing the energy received from the power receiving circuit until sufficient energy is stored so to be transferred to the power charging circuit, electrically connected to said Power Receiving Circuit; and
