His company, BatteryWerks, offers a rechargeable battery pack and charging system for several Palm device models. According to Jorrie, his 700ma Ni-Cad pack will charge in just two hours, several times faster than any other unit on the market, and it will take 1000 charge cycles, compared to half that for the competition. Currently, the recharging system is only available for Palm devices. A Handspring Visor kit will be coming out later this year. This setup lets you charge the pack while your Palm device is in its cradle, and you can HotSync while charging.
Installation is simple.
HotSync first, of course, and then replace your batteries with the NiCad pack and replace the battery compartment door with the BatteryWerks door. Click picture for a larger image. You can then plug it into an AC adapter power block or into your vehicle's cigarette lighter. The auto adapter has large grip wings, making it very easy to plug in or unplug. The package includes the NiCad battery pack, AC power brick with car lighter plug, car adapter cord, and the replacement battery compartment door.
