The Sinewave Cycles Revolution is a bicycle dynamo powered USB charger. It converts electricity generated by hub dynamos to USB output, allowing users to charge USB-powered devices while riding. A built in overload protection circuit prevents the unit from drawing too much power and over heating. The electronics are encapsulated in epoxy so they cannot be damaged by dirt, water or vibration.
Use the connectors supplied by your hub manufacturer to wire the Revolution to your dynamo. No connectors are included.
