Need the device to convert the AC from the Hub to DC for the USB plug. it is wired to the Hub,

it takes the power Usually going to the headlight.

You can also just bring Your Mains charger and plug it in to charge your Phone at Lunch or breakfast stops ..

You Kindle may be too much to ask of the 6V 3W available , so there you will have to charge it while sitting somewhere with Power.
a Campground you Pay For may have power at the camp spot , for their Motor Home Campers..

there will be a faster drain running the Phone , that the Hub can provide , so leave things Off Most of the time.


explain " break dynamo hub"? broken or it has to have a Brake, too ?
