I talked to a Brunton tech rep about a system that would help me charge a laptop, sat phone, AA batteries, and a GPS for fieldwork in the arctic. He suggested I use the SolarRoll 9 with a Brunton SOLO 7.5 amp/hr lithium polymer storage device (see: Amazon). The SOLO weighs about 4 lbs., has an inverter with a 3-prong outlet, and would be safer for charging a laptop. I haven't tried this yet - may end up getting the SolarRoll 14.

I'm not sure if I'm the one to answer this question because I am kind of seeking the same information. I just bought the solarroll (9 watt) and now don't know how to hook anything up. All of my cameras and laptops do not take the male and female plugs. I believe the only thing you can do is buy all of the car chargers for the products you want to charge (because the solarroll comes with the car charger).
