Thanks for the details. The one I had was smaller, just two panels, although each panel was slightly bigger than the ones on yours. Stability was the main problem, no way to plug that directly into a phone, because it would destroy the battery. It came with a power bank, very robust one, and the idea was to charge the power bank during sunny times, and use it to charge devices later. Maybe I will try it again during my next trip, just for fun, as I probably won't do any overnight.
Have a great day, !ALIVE
