Anyone have any experience with solar chargers? I am about to buy a camera to record my rides (probably mobius) and have been thinking of how to keep it charged. I go on long motorcycle rides often 12 hours or longer so relying on the battery in the camera (which lasts probably 2 hours max) is not good enough. I have found several different chargers on amazon and ebay and one which seems interesting is called the Opteka BP-SC6000. Would something like this work to keep a mobius running for 12 hours and where would be the best place to mount it on a motorcycle?
