What problem are you trying to solve? How long do you need your iPhone to run? My policy is:
For rides up to 6 hours, I charge up my iPhone and use it. For rides over 6 hours, up to 15 hours, I charge up my iPhone and carry one 2200 mA-hr USB battery. The battery weighs ~70g, about the weight of one PowerBar. I bought them from Adafruit, but there appear to be much cheaper sources: https://www.adafruit.com/product/1959 For rides over 15 hours up to 22 hours, I charge up my iPhone and carry two 2200 mA-hr USB batteries For rides that cover multiple whole days, I carry two 2200mA-hr USB batteries. In the daytime, I charge the depleted battery with a Sinewave Revolution. Maybe the problem you are trying to solve is: I need to ride now. My iPhone is dead now. All my backup batteries are dead now. My dynamo can't power my iPhone. My iPhone must be running at all times. What do I do? If that's the problem, I don't have a suggested solution. I have not attempted to charge my personal iPhone with my Sinewave Revolution to confirm your observation that it is impossible.
