Sinewave Cycles USB Dynamo Powered Charging Device

For endless adventures, the Reactor USB Dynamo Powered Charging Device from Sinewave Cycles can be used to deliver an unlimited supply of power to your smartphone, GPS computer or any other standard USB-powered device. This neat solution replaces the stem top cap above your star-fangled nut in a threadless steerer tube, and power comes via your dynamo (not included), with a pass-through for the 6mm bolt. The interface delivers a maximum current of 1 Amp, and a steady 5V of power when up to speed at 9 miles per hour (14.4 km/h).
