There has been a lot of talk about using hydrogen fuel cells over the years, but rarely do you actually see them. Well if you want to get in on the eco-friendly ways to recharge your gadgets, this Powertrekk charger might just be what you’re looking for.

The PowerTrekk is a small hydrogen fuel cell that is crafted almost entirely from recycled electronic waste materials, which is always good to see. Inside you’ll find a small PowerPukk, which is where the magic happens. When you add water to the charger, the Pukk will begin converting it into energy, allowing you to instantly charge whatever USB-powered gadget you like. Or, you can just charge the battery contained within the PowerTrekk. Unfortunately they don’t currently have a lot of information like pricing and availability.
