Outdoorsy types are sure to love mobile solar chargers, but what about those who rarely see sunlight? (No, we're not referring to 'Twilight.')

Easy Energy will launch the YoGen, a mobile charger that solely relies on hand power. The pocket-size charger lets you generates energy by repeatedly pulling a ripcord, similar to the way a lawnmower is started.

YoGen Max generates energy through a foot pedal.

The Las Vegas-based company created this product as a part of its mission to 'satisfy the enormous worldwide demand for practical, compact, 'green energy producing' manpowered chargers.' Easy Energy is also in the process of launching YoGen Max, a laptop charger that lets you generate energy by continually pressing a foot pedal.

Similar technology can be credited to Baylis, a company that created a wind-up MP3 player in 2008.

Preorders can be placed at the YoGen store and will ship within the next month. The $40 charger is available in black or clear, but you'll have to choose between Apple and Mini-USB tips or LG, Sony Ericsson, Nokia and Micro-USB tips.
