    Hi

    I am planning to make a phone charger powered by a bicycle dynamo like the one seen here on eBay

    http://www.ebay.co.uk/itm/BICYCLE-B...isure_Cycling_Bike_Lights&hash=item20c484dcf5

    The phone would be a Nokia Lumia and will be used on a sponsored charity cycle ride from Middledbrough to Paris.

    The rider would like to be able to keep his phone charged up but does not want to pay the high prices of an off the shelf item.

    My question, is this a viable project using the above generator and would the cost of the parts be much less than an off the shelf item.

    Thanks

    6V may not give enough headroom if the dyno output really is 6V and the Lumia needs 5V at its charging input. What is the output voltage and current rating of the usual Lumia charger?
