AutoSol ThinFilm 12V 7W: The 12v Solar Battery Maintainer 7W is a 7W Solar Panel which operates at 12V. It is perfect for a number of portable applications and battery charging uses and it utilizes the latest amorphous solar technology providing optimum efficiency and performance even in low light conditions.

    Love the Panel, they save space because it is allow to fold when you want to store it, plug and play setup. so it is easy for a woman to use.

  2. 4 out of 5


    Nice quality with a very good price, the reason I give four stars is it doesn’t come with jumper connections and the lighter plug. But Silicon Solar sell them too, So the whole deal isn’t too bad.
