The Horizon Technologies MINIPAK portable electronic device charger is designed to meet the needs of users who want more portable energy in one package, at a lower cost than existing rechargeable or disposable battery-based options. The MINIPAK portable electronic device charger is a palm-size universal portable power charger and power extender for ANY electronic device requiring up to 2W of power. Devices that are compatible with the MINIPAK include cellphones, 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 up to 2W delivered through a standard micro-USB port and a multi-choice cable. The device is supplied with 1 refillable and ready to use solid state hydrogen cartridge. While a cartridge replacement and filling infrastructure develops, Horizon has taken the extra step to develop a home refueling system called "HYDROFILL" - sold as a separate accessory for added convenience. The MiniPAK is positioned to address gaps in providing energy "on the go" for power-hungry device users, as well to provide a low cost energy storage option for emergencies and long duration off-grid power users.
