BioLogic Reecharge Dynamo Kit
Bicycle hub dynamos are the perfect source of green power - a dynamo generator embedded in the hub generates free electricity while you ride. The ReeCharge Dynamo Kit allows you to use this power to charge your iPhone on your bike through the optional ReeCharge Case and ReeCharge Case Bracket. Perfect for long tours where you need to keep your phone charged. A power converter with safety circuit conditions the power and keeps the device you're charging protected from surges.
