While you're waiting for your Wonder Twin powers to activate (keep drinking that tequila!), it doesn't hurt to have a backup power plan. The Brunton SolarRoll is a flexible solar panel that is tough, lightweight, packable and comes in 4.5, 9 and 14 watt (15.4 volts, 900mA) versions.
The SolarRoll 14 puts out enough to charge a laptop, camera, or sat phone, measures 12x57 inches and easily rolls up to 3 inches in diameter. It maintains flexibility even after a long time in storage, and doesn't do too badly in the cold. The 14 weighs in at a pound even with the cigarette lighter adapter, one of three that come with the unit. The other two are a 4-prong DC (2.5mm, 3.5mm, 4x1.7mm and 5.5 x 2.5mm) and a 12V cable with alligator clips. Most people will probably want to charge laptops and smaller electronics, and there's a good chance that the included plugs won't work so be prepared with a car adapter.
In use the SolarRoll works great. Just unroll and drape over the tent, rock or backpack. With a little ingenuity you can pretty much hang it anywhere. Even on cloudy days you can trickle charge most batteries. The SolarRoll has reverse current protection so you can leave things plugged in overnight without worrying about overcharging. It's also waterproof and much tougher than glass panels. The included plastic case is quite useful for storing other small items; it's about 16 inches long and a little bigger in diameter than a quart bottle. If you need portable power, the SolarRoll is a great solution.
