Not a comprehensive overview - I tended to research extensively first and settle on a specific system. So these reports are based on my experience of a couple of systems on long tours.

IH, thank you for the links! Great reading and well-documented research.

The Goal Zero Nomad 7 is twice the collection surface and delivers twice the energy output compared to the model I have, the 35 which is really "3.5."
I'll be riding all summer with the iPhone in GPS mode using MapMyRide and other apps, sucking power form the Goal Zero 4-AA pack or running from the solar panel which might be lashed to the fairing on my recumbent.

Hi All
I have a B&M Son 20 generating front hub. it has about 6w power. I have it wired to a 'The Plug' which is inserted into the top of the steering tube. The Plug has a usb port. I mount my smart phone or light directly next to it and plug it in, easy as pie. I use my phone with iBike as my bike computer. I find the generator will keep the phone charged at whatever level it starts at. This is pretty phenomenal as the gps is going and sucks a lot of power. The light is no problem. In fact, a friend's light was dying, we plugged it in. After a few minutes it had enough power to come on from cold dead!
One note: I have to be going about 12 mph to get the smart phone charging, under that it wanes slowly.
Enjoy the touring.
