This motion-powered portable charger will target those who tend to be on the move, but do not have consistent access to a power outlet. Tipping the scales at a mere 11 ounces, it is capable of generating enough juice to power an iPod nano, so 26 minutes of walking is said to be sufficient to help a 3G smartphone work for another minute as you yak away.
We suspect that this isn’t going to be a mainstream hit – asking Americans to walk more is a hard enough task as it is already, so an incentive like storing extra juice for your gadgets while moving might be pushing the envelope.
