"Today's Smartphones use much more power, increasing the need for a more
 efficient way to recharge when on the go," said Steven Schwartz, Vice 
President of Merchandising and Product Development at Brookstone. 
 "Lilliputian's groundbreaking technology provides power, wherever and 
whenever you need it. This breakthrough aligns well with our commitment 
to innovative solutions that make life easier."
Fuel cell maker Lilliputian Systems today announced that Brookstone will
 be the first retailer to carry its portable USB power source, which 
will be sold under Brookstone's brand. The fuel cell device is about the
 size of a thick smartphone, and the lighter fluid-filled cartridges are
 about the same size as a cigarette lighter. It's a big step forward 
both for Lilliputian Systems, a 10-year-old spin-off from the 
Massachusetts Institute of Technology, and for portable fuel cell 
technology in general. Several fuel cell companies have developed 
portable power systems, but a number have failed. The new fuel cell will
 charge any device that has a USB cable.
    In a test lab, Lilliputian systems engineer Souren Lefian plugged a white iPhone charging cable into the Mobile Power System prototype and forwarded a few watts to my phone. There wasn't much that was thrilling about the process, aside from knowing that I can now claim to have gassed up my iPhone. Then, Lefian (pictured at left) switched cables and charged up his Android phone. On Lefian's computer screen, a graphic showed how much fuel was left in the MPS' tank, as well as how many watts it was sending to the phone, and how full the phone's battery was.
 
According to the manufactuer, the device will be able to charge an iPhone 4 between 10 and 14 times with one 
cartridge, which can work out to approximatly one or two weeks of use 
for most users.
