A fuel cell that is rated to produce 55,000 mWh (about two weeks' worth of power for your cell phone, less for a tablet) is being shown at CES. The Nectar fuel cell is made by Lilliputian Systems. It's advertised by Brookstone. Price is $300.

The Brookstone web page is http://www.brookstone.com/nectar-mobile-power-system
Fuel supplies for the Nectar are sold separately. A pair of replacement fuel supplies costs $19.
Why consider an expensive fuel cell instead of a bunch of batteries? The Nectar and one fuel supply weighs 235 g, or about 8.3 oz. The set is smaller than a paperback book. The Nectar is more convenient than a solar panel that recharges AA cells (lighter, works in the dark).
