PowerTrekk is a pocket-size, lightweight charger for users who spend time away from the electrical grid. Providing instant power anywhere, PowerTrekk uses advanced fuel cell technology which cleanly and efficiently converts hydrogen into electricity. With its rugged, waterproof casing and robust technology on the inside, PowerTrekk is designed to match demanding requirements. PowerTrekk is both a portable battery pack and fuel cell. The portable battery pack can be operated on its own as a ready source of power or storage buffer for the fuel cell. The fuel cell enables instant charging from a depleted battery state without ever needing a wall charge. Users simply insert a fuel pack and add water. To charge portable devices – for example mobile phones, cameras and GPS devices – users connect a device to PowerTrekk via a USB port. PowerTrekk was developed by myFC, a Swedish fuel cell technology company that develops solutions for powering portable electronics. Having secured numerous patents around proprietary shape-flexible fuel cell systems with record high power density, PowerTrekk is the first commercial portable charger using myFC technology. Since the hydrogen fuel can be supplied from several alternative sources, the system is ‘flexifuel’. The chemistry process is safe and eco-friendly, and the only by-product from the fuel cell is a little water vapour.
