IRVINE, Calif.--(BUSINESS WIRE)--Dec. 20, 1999

Comarco Wireless Technologies, a subsidiary of Comarco Inc. (Nasdaq:CMRO), Monday announced the award of a battery recharging patent by the United States Patent Office.

U.S. Patent Number 5,949,213 "Method and System for Charging Rechargeable Batteries" was issued on Sept. 7, 1999.

The invention employs a novel technology for charging rechargeable batteries such as those found in cellular telephones, notebook and handheld computers, digital cameras and other portable electronic devices. This technology complements and is compatible with Comarco's ChargeSource(TM) family of portable power systems for which three U.S. patents have been awarded.

"We took a close look at the way today's batteries are being charged and realized that it's unnecessarily complicated for the device itself to control the charging of the battery," said Tom Franza, president of Comarco Wireless Technologies Inc.

"Just about all portable electronic devices are tasked with charging their internal batteries. This adds unrecoverable cost to its design, and in the long term doesn't necessarily provide for a high performance battery."

Dubbed ChargeSource SmartBattery(TM), the new technology from Comarco allows for a direct connection between the original power source and the battery, bypassing the device to be charged altogether.

"The SmartBattery will control its charging parameters and environment, freeing up the device to function fully, even when being charged," said Tom Lanni, general manager of Comarco's Mobile Power Products division.

"We forsee batteries utilizing ChargeSource SmartBattery technology will allow for very quick recharge times under most applications."

"This latest patent award underlines Comarco's commitment to develop and deliver the finest products for the mobile and wireless markets," said Don Bailey, CEO and president of Comarco. "Comarco will continue to expand its portfolio of power products and technologies for all types of mobile devices, in all applications."

ChargeSource power systems have been available at retail since early 1999 and are compatible with a wide range of portable computers including most popular Compaq, Dell, IBM and Toshiba models. ChargeSource systems that support portable computers and cellular telephones are ideally suited for mobile professionals who desire the convenience, simplicity and reliability of a single AC power system, or as a stand alone, secondary power system for travelling purposes.

ChargeSource compatible products are available under license from Targus and Port and are available through leading distributors including Ingram Micro, Tech Data and Merisel, and are also available at national retailers including CompUSA and Best Buy.
