I am try out a new solar system, I bought a 14W rollable panel and will use it to charge my lapto via a 12V "cigeratte lighter" socket. I also have a 12V charger to charge 4 AA or 4 AAA batteries. The battery charger has a USB outlet, so I will charge my iPod and camers with the AA's. I am going on a 6 month tour, so this is a list of ALL my electronics and how I will charge them:
Netbook with oversize battery - direct from solar panel
Head light, tail light, flash light, all use AA or AAA batteries charged from solar panel
iPod - USB from AA batteries or computer
Camera - direct from solar panel
Phone - USB from computer or AA's
With a 14 watt panel even if half of it is in the sun, I still should be producing enough power to keep things charged. I will be on the Great Divide route, so 120 volt power will not always be avaliable. I am bringing a 120 volt charger for the laptop just in case, and the battery charger has a built in 120V adapter.
I have a journal at crazyguy with a few pics of the panel, and I will be paying close attention to how well this works, hopefully I never have to use 120V power. My journal is at
