Simplicity is best

Was looking for solar charger that could charge cell phone, headlamp, small GPS, etc. in a wide variety of environments, from boat to backpacking. I'm a professional sailing captain but also spend a lot of recreational time in the mountains. From using solar panels on boats, I know solar panels work in direct proportion to their size, period. The bigger the surface area, the more energy. There are other, fancier chargers out there that charge batteries that then hold a charge to charge your device, but that seems like a lot of extra weight, hassle, and things to go wrong. And their surface area is smaller. This simple device unfolds to reveal a lot of surface area, and has a single USB port to plug into your device. No regulator, no battery, nothing but solar panels. I've only just tried it in the kitchen window so far, but it seemed to start charging my phone ok. Takes a while, but plugging into a 110 outlet this ain't. Seems to be a good rugged design that folds up nicely to slip in a pack.
