This is the perfect emergency or off grid folding solar panel to have in your home. It is rated at 21 Watts and 5 Volts so it can charge your cell phone, camera, tablet and other small electronic devices which take 5 Volts.
There are three USB outputs on this folding solar panel. This is more than I have yet seen on any such device.
This PwPAM folding USB solar panel is also thinner than any I have yet seen to date. The Panels are coated with a scratch resistant coating to protect them from normal use and wear.
They are weather resistant from the front face.
The package includes a carrying case and two carabiners so you can attack it to your backpack on the go. I can see this being useful for camping, hiking, fishing, boating or to have around for disaster or emergency.
