So I've been thinking about external battery chargers for my phone. Has anyone tried one of these in the link below? Not necessarily this one but one like it.

My worry is finding a place to charge my phone because I'm planning to stay in hostels/motels as little as possible. If anything, winding this thing while hiking might give me something to do for a bit. Thoughts?
