THE VELOCHARGER DYNAMOS

Hub Dynamos

The VeloCharger Hub requires power to be supplied from a standard 6 volt 3 watt Hub Dynamo. This is fitted in the hub of the front wheel. You may already have a hub dynamo fitted, to supply a lighting system: if not you can purchase one and have it fitted to your own front wheel, which is a task best performed by your local bike shop, or you can buy a dynamo already fitted to a wheel to replace your own.

The choice of dynamo is left up to the user. Many different models are available at various prices. As a rule, the expensive ones may not provide more output, but are more robust and therefore may last longer.

Note that the newer 1.5 watt dynamos are only suitable for lights and will not provide enough power for charging USB devices.

THE CHOICE IS YOURS

Where Can I Buy One?

Suitable dynamos or dynamo/wheel combinations are available from a variety of sources, including Spa CyclesAmazon, and Rose Bikes. Of course you may already have a hub dynamo fitted to your bike in which case you just have to connect up the VeloCharger using the cable supplied in the kit.

Charging with a Dynamo

Hub dynamos are usually rated at 6volts 3watts, however the output varies considerably with speed, and can reach quite high voltages. The VeloCharger Hub is designed to cope with this variation in output. Charging will start at approximately 9mph (14km/h) and will cut off at speeds exceeding 30mph (48km/h) to protect the circuitry.

Hub dynamos require little or no maintenance or adjustment and are therefore the preferred choice for long term reliability.
