USB fuel-cell prototype unveiled
25 hours of power
A portable fuel-cell’s been unveiled that its maker claims can provide up to 25 hours of power and support every device from MP3 players to mobile phones.
MTI Micro's Mobion fuel-cell: prototype
Mobion is still at the prototype stage, but manufacturer MTI Micro has promised to commercially launch the fuel-cell pack, which is powered by interchangeable methanol cartridges, by the end of 2009.
At the fuel-cell’s core is the firm’s proprietary “third-generation Mobion chip”, which is based upon methanol fuel and passive, direct methanol fuel-cell (DMFC) technology. The firm hasn’t said how much methanol is stored inside each cartridge.
More than a day's power from one cartridge
To give you an idea though, rival Panasonic has already unveiled a DMFC battery able to provide 20 hours' power from its 200cc methanol capacity.
Mobion has a USB interface so it can be connected into a host of gadgets. MTI didn't say whether it would also offer a version capable of driving a laptop.
Nonetheless, a single Mobion cartridge will provide one month’s worth of mobile phone power, enough juice to take 6000 pictures on a compact camera or 100 hours of video playback on an MP3 player, the company claimed.
Mobion, which looks to be about the size of a laptop battery, has “smooth edges for an easy grip” and interactive LED lights which presumably indicate when the cartridges are full and empty.
A potential price for Mobion hasn’t been given yet.

"Methane is an explosive gas"
It's a good job this device contains absolutely no methane then.
re: Airplane safe?
Erm... and lithium ion batteries aren't explosive?
Excellent! I have a, rather nice looking, very slim and light battery pack that I bought from Maplin for £10 and that I can recharge via the mains or from any powered device with a USB port and that I can use to charge virtually anything. Whereas this device is large, heavy, requires bespoke cartridges that I'll never be able to get hold of and can only charge something as long as it will draw power through it's USB port.
How can this NOT be banned on airplanes? Methane is an explosive gas
