Abstract
A portable auxiliary power source system and method of the present invention facilitates extended portable use of a handheld computer without being unconnected to a fixed power source. A present invention portable auxiliary power source system is mobile and accommodates energy resources that are easily replenished. In one embodiment a portable auxiliary power source system includes a battery compartment, coupling component and electrical interface. The battery compartment holds a energy source such as battery. The coupling component is configured to couple with a handheld computer. The electrical interface is fabricated to provide a communications port for communicating electrical signals from the portable auxiliary power source system to a handheld computer. In one exemplary implementation of the present invention the battery compartment includes terminal tabs comprising electrically conductive material (e.g., copper) adapted to contact a battery terminal and provide an electrical path for electrical charges along wiring to the electrical interface. The electrical interface comprises ports of electrically conductive material configured to provide a path for conveying electrical ch…
