A quote from the article:
>> Black & Decker PowerToGo Review
You know what you do when you don't have a place to get some juice for your gear? You get portable power. Black and Decker created this nifty little contraption called the PowerToGo. You can get it in 3 flavors, 10w, 20w, and 100w. I opted for the 20w because I didn't figure I would need much more than that to power my PSP and cell phone, and because the 2Ah battery that comes with it is half the weight of the 4Ah battery inside the 100w version. Weight is an issue when traveling.
