Solar Panel to charge a smart phone?
Not interested in spending a great deal, mostly because it won't hurt as much that way if it gets taken. Doesn't have to plug direct into the phone, charging a battery which is then used to charge the phone would be fine. In a perfect world it would just sit on a rack or on top of a pannier and do it's thing. Not anticipating a great deal of after-hours phone use, but nowadays folks get worried if you don't check in.
