When I unboxed this, I was quite surprised at the feeling of it. It felt hefty for a bunch of solar panels. The texture was something you would expect from something you would typically use on a hike. It feels as if it could be quite resilient from the elements and that it would survive easily. Output is low but that's expected since solar panel conversion efficiency hasn't really improved that much over the years. It's a nice-to-have item for anyone who likes going outdoors.
