Classified as a piece of hiking and camping equipment, this could be a potentially life-saving tool. Relying on a germicidal UV light that is capable of destroying up to 99.9% of bacteria, viruses and protozoa, 48 seconds is all it takes for the SteriPEN Freedom to handle 500 ml of water. There is a green light gauge to inform you on whether it is safe to drink the water or not.
Need to juice it up? Just plug it into a USB port on a computer, power outlet or a compatible solar charger. A single charge can deliver up to 40 treatments, while the UV lamp life has been rated at 8,000 treatments of 16 oz (0.5 L). In addition, it doubles up as a flashlight for those dark and lonely nights. Expect the SteriPEN Freedom to arrive from this fall onwards for $119.95 a pop.
