Abstract
A charging apparatus for a portable rechargeable electronic device is described. The charging apparatus contains a substantially flat conductive surface for receiving the electronic device placed thereon. Small conducting nodules of the device mate with the conductive surface to charge a rechargeable battery of the device. Charging may commence upon placement of the device. The surface may contain a positive and a negative electrode. The surface may have lips placed around the perimeter to form a tray like structure. Synchronization with a host system and the device may occur wirelessly.
