Abstract

A portable electrochemical power supply for handheld electronic devices, such as cellular telephones, is disclosed. The power supply includes a housing with an electrical connector, a circuit board, and a removable electrochemical cell disposed therein. The circuit board carries power supply circuitry which receives electrical energy from the electrochemical cell and provides a power supply output for powering an external device.

Claims

1. A power supply, comprising:

a housing having an interior surface and an exterior surface, wherein the housing includes electrical contacts for receiving power;

an electrical connector disposed through the housing, the connector having a first end accessible from said exterior surface;

a circuit board disposed within the housing, said circuit board in electrical connection with the electrical contacts and the connector, the circuit board receiving an input voltage less than about 1.90V and providing an output voltage through said connector greater than about 3.00V; and

wherein the housing comprises a first section and a second section, wherein said first section comprises said connector and defines a first end of said housing, wherein said second section is tubularly shaped and includes an open end and a closed end, and wherein said first section is removably joined to the open end of said second section.

2. The power supply of claim 1 wherein said first section is electrically nonconductive and said second section is electrically conductive.

3. The power supply of claim 1 wherein said first section is optically transparent.

4. The power supply of claim 1 wherein said the first end of said connector is recessed below the first end of said housing.

5. A power supply, comprising:

a housing haying an interior surface and an exterior surface, wherein housing includes electrical contacts for receiving power;

an electrical connector disposed through said housing, the connector having a first end accessible from said exterior surface;

a circuit board disposed within the housing, said circuit board in electrical connection with the electrical contacts and the connector, the circuit hoard receiving an input voltage less than about 1.90V and providing an output voltage through said connector greater than about 3.00V; and

wherein said housing comprises an opening therethrough.

6. The power supply of claim 5 wherein said opening allows gas in the cavity to pass therethrough.
