The ZPAC 40 Zinc Air Powerpack is a portable charger for mobile devices that does not need an electrical outlet; it uses fuel cells. You can use it in the middle of nowhere to re-charge your mobile phone and itâ€™s got enough power to do that ten times.
Itâ€™s made by Power Air Corporation based in Livermore, California. PAC is a clean energy company which holds exclusive licensing rights for the Zinc Air Fuel Cell (ZAFC) technology.
The ZPAC 40 provides the equivalent energy of 40 AA alkaline batteries in a compact package (102 x 63.5 x 19mm, 310g) that fits easily in a shirt pocket. It can be stored unused for up to two years. The integrated fuel cell is recyclable, according to PAC.
