USB Dynamo Powered Charging Device + Fitting
We have two options here for a dynamo powered USB charging device - The Sinewave Reactor and the Sinewave Revolution. Please also see the Sinewave Beacon in headlights for a dynamo front light with integrated USB charger.
N.B. these are only available to purchase when buying a Stanforth bike with an ahead stem (and non carbon steerer).
Starting with the Sinewave Reactor:
The more we use Sinewave products the more we are impressed. Sinewave seem to have the edge over other brands we have tried in their level of waterproofing. Although the top cap USB port is exposed it is designed to be waterproof, for this reason it is our preferred top cap style USB charger.
The Sinewave Reactor takes the performance of the Revolution dynamo-powered USB charger (detailled below) and shrinks it into a package that fits above the star-fangled nut in a threadless steerer tube, with a pass through for the 6mm bolt. The only visible part is a custom CNC-milled stem cap holding the USB connector. The cap is only 9.8mm tall and available in silver, black, red and blue.
Sinewave Cycles Revolution USB Dynamo Powered Charging Device
The Sinewave Cycles Revolution is a bicycle dynamo powered USB charger. It converts electricity generated by hub and bottle dynamos to USB output. The Revolution allows users to charge USB-powered devices whilst they ride.
This does not sit in the steerer tube like the Plug III. The Revolution can either be cable ties to the frame, bars or stem or sit in a frame or bar bag.
The Revolution is made in the USA
