Yo-Yo-Like Charger, YoGen Mini-Power Generator Charges Cell Phones Without a Power Cord

What can you do if you are out of power and need to charge your cell phone?  There are battery boosters, and fuel cell rechargers and now a new device that cranks energy with a yo-yo-like string.

The YoGen handheld charger for portable electronics was launched at CES and received recognition as a "Best of CES 2010" item by Gadget-Gurus.

The 100 percent green, fully-sustainable device that creates levels of charge sufficient to ensure sustained use when a battery runs down. YoGen Sells for $39.95 and could come in handy in cases of a disaster or just when you forget to charge you phone. It works with most cell phones including iPhones, USB devices and Bluetooth headsets.
 

YoGen can echarge any small-to-mid-sized personal electronics device by offering the industry's leading ratio of energy output to input. 

Through repeated pulls on an attached ripcord, similar to the motion of a Yo-Yo, YoGen's internal alternator generates power in to charge everything from cell phones, iPods, PDAs and MP3s to Gameboys, GPS units, cameras and other devices. The alternator interfaces with an energy-efficient electronic stabilizer and transmission to transfer linear kinetic energy through a patch cord from the compact, ergonomically-designed unit to the electronic device.
