Described as a “plug-less charger,” it will allow users to recharge their electronic devices’ batteries wherever they are – as long as they’ve stocked up on butane. The device is about the size of a thick smartphone, and features a solid oxide fuel cell membrane deposited onto a silicon wafer. It generates power using recyclable butane cartridges, which are around the size of a cigarette lighter. According to LSI, one of those cartridges should provide “several weeks of ‘always available’ Personal Power” – this is reportedly five to ten times longer than the run times offered by similarly-sized batteries.
