Very good! I had researched it before buying it, of course! It captures 40w in the sun, just as it says! Ideal size for transportation!

Very reliable and sturdy construction but with a basic weight. It can fit an A4 size in the backpack and laptop bag. You will need to buy the cables for the devices you want to charge, if you don't already have them.

I bought it for emergencies when there won't be any other source of energy. It is reliable and does what it says. It is small in size when closed! The fact that it is waterproof played a crucial role for me. Also, it requires careful handling so as not to damage any panel, as it will affect the whole thing. From what I understood, the panels are connected in series, so if one panel is closed, it doesn't work very well. Charging times are good and the quality is good too. My only complaint is that it doesn't come with a DC cable included
