### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice
  

*by T***N on Reviewed in the United States on July 27, 2014*

I'm this using solar panel to charge my camping van house battery. I was running a fan all night and my battery was at 95%. I placed this on my dashboard and over the steering wheel as I needed to leave the van for the day. It was a cloudy/sunny day. So no bright sunshine hit this panel for 12 hours. It went to 100% at the end off the day. Happy with it. Only thing is the clamps, flimsy and at one point I know they will have to be replaced.
