Our device YoGen® is a slim pocket-size hand-powered electric charger driven by repeated pulling a cord in a similar to Yo-Yo string. While the self-returning cord is repeatedly pulled by the user, an internal alternator spins continuously, and thereby generates power allowing for recharging the batteries used by any PDA and especially cell-phone while the user can keep using them, e.g. `staying on talking`..
Since human-power source is actually unlimited and permanently available- no additional batteries to dispose of or extra weight to carry.
YoGen® is based on a unique extremely slim patented high-efficiency "on-board" alternator integrated with an energy-saving electronic stabilizer allowing for a palm-sized device which provides a quick recharge for any device adapted for charging from 5VDC chargers: cell-phones, GPS, iPOD, MP3, MP4, etc.
The second device we are developing, YoGen MaxT (coming in soon) will provide enough power for laptops and their accessories, professional camcorders, etc. Unlike YoGenT it will be driven by the user's foot in order to provide a long charging without body weariness and interference with main user work.
