Solar powered 12VDC energy source for various gadgets I've installed a solar panel in my car that charges a large 12VDC battery thru a charge controller. It is on a circuit separate from the car's wiring. I wired it from the trunk to the front dash board to a small jack. Perfect for powering small gadgets.
