PowerTrekk offers outdoor enthusiasts an alternative to batteries and solar chargers with its new fuel-cell charger for USB-compatible devices.
The device uses a tablespoon of water from the nearest available source, even saliva in extreme cases, and the PowerPukk fuel pack to convert hydrogen into electricity as it passes through the lid’s fuel cells, delivering 5W of charging power – or enough energy for two charges of most devices.
During the process the chemicals in the Pukk are transformed into sodium silicate, better known as the scrubbing agent in toothpaste. Each Pukk costs $3 to $4.
The device captures excess energy from the hydrogen-to-electricity conversion in a detachable battery in its lid that can be carried and used separately as a spare battery.
The lid can also be charged via USB without the fuel-cell system.
