i'm french so my english is quite poor, sorry for that.
I buy a 20" wheel whith dynamo (3N30). And i would like to charge my phone with GPS (xgps) is on. I don't have a lot of money. The e-werk is great but too expensive.
-i think first : Zzing Smartphone Edition. 99€
and i see the dahon : is less expensive (76€ on evans), 139€ in france.
I see a cheap recharge for iphone but is not very powerful (less 500 ma)
But i'm creep in electronic. It's for a european tour in august 2011 et asia tour en 2013.
Thanks a lot.
