>>531715I bought the GOALZERO Nomad 7 Solar Panel and tested it in the andes between 14,000 ft and 17,000 ft.
I charged my Smartphone, my GoPro Hero 2 and even my battery charger (12V) worked with it. I charged AA and AAA batteries with it.
One feature I did not tested but like to have the option is that you can chain these panels if you need more power or have less sunlight.
