Hand-held inductive charger having concentric windings

A hand-held inductive charger comprising:

• a removable primary coil assembly comprising a cylindrical housing having a handle portion, a cylindrical primary core comprising ferrite material disposed in the housing, a circular primary winding protruding from the cylindrical primary core, and an electrical cable coupled to the primary winding that is adapted to couple power thereto from an external power source;
• and
• a secondary coil assembly comprising a receptacle housing, a cylindrical secondary core comprising ferrite material disposed in the receptacle housing, first and second concentric circular secondary windings disposed in the secondary core that are couplable to a battery and wherein the first and second concentric circular secondary windings have a gap therebetween that is adapted to receive the circular primary winding therein;
• wherein the primary and secondary coil assemblies form a transformer when the respective primary and secondary windings and primary and secondary coil assemblies are mated.

A hand-held inductive charger comprising:

• a removable first coil assembly comprising a housing having a handle portion, a first core disposed in the housing, a first winding protruding from the primary core, and an electrical cable coupled to the first winding that is adapted to couple power thereto from a power source;
• and
• a second coil assembly comprising a receptacle housing, a second core disposed in the receptacle housing, first and second concentric second windings disposed in the second core that are couplable to a battery and wherein the first and second concentric second windings have a gap therebetween that is adapted to receive the first winding therein;
• wherein the first and second coil assemblies form a transformer when the respective first and second windings and first and second coil assemblies are mated.
