A charger for inductively charging one or more battery powered appliances simultaneously includes an external unit configured to inductively provide power to the battery powered appliances. The external unit includes two or more primary coil pairs that are arranged in a circular pattern; an AC power source for providing an alternating current (AC) to the primary coil pairs for generating a rotating magnetic field between respective primary coils of the primary coil pairs; and a processor for driving the AC power source. The one or more battery powered appliances are configured to be arranged inside the circular pattern of the external unit. Further, each appliance includes a secondary coil for enclosing part of the magnetic field and, in response, generating a current for charging the battery of the appliance.
