Someone gave me a Freeloader solar charger:
http://www.freeloadersolar.com/shop/freeloader-pro.htm
Didn't see much use for it for a time. But, I started to think about an upcoming trip on the SHR where I want to have a GPS for back-up navigation. Plus, I need to carry my iPhone for use before and after the hike. My watch-style GPS weighs 4oz with 1 extra set of batteries, but if I want to use it a lot I'll need more batteries = more weight. The Freeloader weighs 6.4oz. I could ditch the GPS and bring the Freeloader + iPhone with MotionX GPS software and free map downloads. I can easily upload my SHR waypoints to the iPhone, which provides much more detailed navigation info (maps!) than my GPS.

Anyway, I'm looking for feedback from anyone who has done similar. Can you get enough juice to keep the iPhone charged with moderate navigation use? Freeloader battery is 1600mA-hr. I do not plan to use the iPhone for any other purpose while hiking. Also,
I know - turn off all the cell service stuff, wifi, etc. The Freeloader doesn't have any obvious way to mount it on a backpack. Has anyone made a holder/mount for this
device? Other thoughts about using this or similar devices for backpacking?

Thanks!
