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. The new fuel cell will charge any device that has a USB cable. People will be able to buy refills and fuel cells online, through Brookstone catalogs, or at stores (In United States). Unique technology inside the fuel cell allows for longer charge time than previous portable fuel cells gives. Lilliputian's fuel cell will be able to fully charge, for example, an iPhone 4 between 10 and 14 times with one cartridge. That can mean a couple weeks of use for many people.
