Some facts to mention about the 40w solar panel

One of the bests around, and brilliant customer service. 

It is better to turn off a laptop before charging. That is because some laptops need a large current when operating.

It is best to charge a large battery that is compatible with this of a laptop.

With larger voltages this product will reduce the voltage drop. So the large voltage would not damage the smaller devices.

It is a good idea to cover the solar controller, not the solar panels, when in the hot sun. This is because the hot sun can damage the solar controller.

Cover it with a cloth or a towel or something.
