Abstract
The present application concerns handheld electrical generators for charging mobile electronic devices. In one representative embodiment, a manually powered generator for charging a mobile device comprises a first magnet array having a plurality of magnets arrayed in an annular formation on a first surface, a second magnet array having a plurality of magnets arrayed in an annular formation on a second surface positioned opposite the first surface, and a torque input member. The generator further comprises a rotor having a serpentine trace of conductive material disposed between the first and second magnet arrays. The generator is configured to be incorporated into a handheld case or shell for containing the mobile device.

30. A method of charging a mobile device, comprising:
-
providing a case for a mobile device comprising an electrical generator in communication with the mobile device, the electrical generator having a torque input member interconnected with a rotor by a gear assembly, and one or more magnets disposed adjacent the rotor; rotating the torque input member; multiplying the rotational frequency of the torque input member with the gear assembly; rotating the rotor adjacent the magnets at the multiplied rotational frequency to generate electrical current; and conducting the electrical current away from the rotor and into the mobile device; wherein the electrical generator has a thickness of less than one centimeter and is configured to generate a continuous electrical output of about five watts.
