Lilliputian Systems Inc. introduced a mobile power system at CES called Nectar, a charging device that leverages MEMS solid fuel cell technology. Nectar's butane fuel and high-efficiency solid oxide fuel cells provide high energy density. Butane is stored in a pod cartridge (left) and then inserted into the mobile power system. Capable of powering consumer devices for more than two weeks, the system charges smartphones, e-readers, and digital cameras that comply with USB 2.0. According to the company, aviation regulators
will allow Nectar to be stowed in carry-on bags.
