hello. ok.
i am looking into the Dahon Biologic Recharge. i am in the United States and they have not gotten back to me yet. the battery is similar to the one i mentioned by Pedalpower+ . there are no customer reviews yet, but i am happy to read it will operate the IPhone GPS app while going down the road. this is what i am looking for; except i will be listening to radio.
i agree and understand the buffer between the hub and the phone, and do not want the AA battery solution.
your suggestion has given me another product to compare as the buffer. thanx
