Medis Technologies Ltd. (New York) announced that it has achieved the technical level in its fuel cell performance to provide continuous power for its first planned commercial product, a power pack to provide uninterrupted power to users of cell phones, PDA's and certain hand-held electronic devices. The fuel cell demonstrated sufficient power to enable a laboratory-tested power pack unit to operate the phone while fully charging a totally discharged battery. Each refueling of the power pack is planned to provide six to nine hours of talk time, or over two charges of the battery.
The power pack uses the battery until it is depleted of its charging capability and is then connected to the battery through the phone's existing charging port. The power pack can then either remain connected to the device, or be disconnected and then reconnected to recharge the battery when it is depleted of its power. After the power pack has been used for a number of charges or hours of talk, it will be able to be refueled in a matter of seconds by simply replacing the fuel cartridge and throwing out the old cartridge.
