The promise of the portable fuel cell has been around for some time. There has been promise of portable fuel cell technology for some time, but we have yet to see any come to market. Horizon is promising the release of their fuel cell charger later in 2010. Horizon is offering small packs to refill the fuel cell once empty that contain Hydrogen which is then converted to electricity.
"palm-size universal portable power charger and power extender for ANY electronic device requiring up to 3W of power. Devices compatible with the MiniPak include cellphones, but also smartphones, gaming devices, GPS handhelds, small lighting devices and MP3 players. The MiniPAK device integrates a passive air-breathing fuel cell and a "solid-state" hydrogen storage unit. The MiniPak DC power output is 2.5W (5V, 400mA), delivered through standard micro-USB port and a multi-choice cable. The device is supplied with 2 refillable and ready to use solid state hydrogen cartridges and a highly innovative home refilling station set to eliminate past concerns over fuel availability and cartridge replacement infrastructure. The MiniPAK is positioned to address gaps in providing energy "on the go" to power-hungry device users, as well as a low cost energy storage option for emergency and long duration off-grid power users."
I would love a fuel cell based device and to have it be reasonably priced. We’ll all find out later this year for ourselves if Horizon releases as promised.
