I was thinking about mounting this one on the back of a car dock so I don't need to run a cord down to the 12v outlet. It would sit on the dash all day and charge/power the Droid and it could run off the battery if I needed it at night.
Thanks rmr, I have done some research and have not found any devices that are perfect...I'm not sure that solar technology has reached a point where it is practical. Ill keep looking.
