While pedal power can be used to get to work it can also be used to power up your devices. And the BikeCharge Dynamo from Hong Kong-based iBikeConsole uses the same pedal power that moves to the bike to juice the phone. It can be installed on a bike and it acts as a DC generator that is can power up devices via a USB port.
While it could take two to three hours of pedaling to get a full charge, it could be used during a regular commute to “top off” a phone or at least get enough power for a call or two. It features a waterproof design that can stand up to the elements but since most phones aren’t we’d suggest the appropriate case just in case the weather ruins the ride home.
