Brunton's SolarRoll are flexible solar panels made for powering electronic equipment on expiditions. The rolls weigh less under a pound and can output up to 14 watts of power, which in was enough to recharge a laptop computer but not to run direct off of it..

A SolarRoll can charge digital cameras, camcorders, GPS devices, satellite phones and other products in the most remote regions of the world. The amorphous solar cells are effective in bright sunlight as well as on partly-cloudy days.  To set up a SolarRoll, you simply unrole the panel and drape it across your tent or any other place in direct sunlight. Brunton includes two cables for connecting to various devices: The first cable has four standard plugs that work with the power outlet found on common devices like laptop computers and satellite phones. The second cable includes a vehicle-outlet connection so it can be used with adapters made to power devices off a car's cigarette lighter.

The standard-plug cable worked with my laptop computer however I recommend that you buy a DC adaptor for your laptop.  This will protect your laptop from the power fluctuation from solar power.  The device has a cigarette plug adaptor that is very handy to attach most devices like iPods, cell phones and a PDAs. To charge those items with the SolarRoll, I would need to purchase the appropriate vehicle-outlet adapter and use it in conjunction with the Brunton cable (www.brunton.com).
