Is there any similar solar panel that can be mounted outside a tent which will charge phones or power banks? It does not need to be so portable but a bit more robust than this folding panel.
Interested in two, especially if it’s fairly lightweight. Anker has a version that’s reasonable weight wise. I backpack quite a bit so weight is a huge consideration. That said, durability is also key which is usually on the other side of the spectrum from weight.
