Ive seen mention for pedal & power and something from motorola, but I
cant find anywhere to purchase such things. I want to trickle
feed/charge my mobile from the hub dynamo when touring. Surely such a
thing exists and works? Most links I find are dead ends or defunct
companies.
Anyone got anything concrete that they have used and can recommend?
I mean, if I can recharge my mobile from a USB port I surely can from a
hub dynamo?
Does your mobile have a charger for an automobile? If so, then you need
to find a suitable way of converting the output from your hub dynamo to
something like the 12-14 volt dc output from a car battery to feed it
into your automobile charger.
If your hub dynamo is already 12 volt then a simple rectifier is all that
is needed. If your hub is the more common 6 volt variety, then a simple
voltage doubler will be required.

Yes. But where is the product I can buy? What is a simple rectifier?
