We have a holiday home in Spain, but it has no electricity connection. In order to still be able to use smartphones etc., we used the 100W foldable solar panel from ALLPOWERS. The panel is delivered folded compactly in its own storage bag. The whole thing looks really well made and has additional punched holes on the sides. You can use the hooks provided there and hang the whole thing up easily and safely somewhere. Thanks to the included cables, you have a wide choice of exactly what you want to charge. We already have a small solar panel to set up to charge a high capacity battery. These could also be charged with this panel. We basically hung it out of the window and put the USB cable in through the window. This meant that anyone who wanted to charge their device could simply plug it in and place it on the windowsill. Thanks to the large area, a lot of electricity is also generated. And when you came back from the beach, for example, you could use it again :-) Folding it up again is also easy and you can put it back in the transport bag ;-) So it's now patiently waiting for our next vacation :-D All in All in all a great and nice large solar charger. We are very satisfied :-)
