This review is from: Goal Zero Nomad 7M Solar Panel (Automotive)
Despite the fact that I followed all the manufactures instructions on placement of the panel. Tried it on sunny days and on cloudy days. It was never capable of generating enough power to charge my smart phone. So I then tried to charge it using the goal zero battery, this was just as bad at holding a charge. Very disappointing. Sent them back.
