Gadling gear review: SteriPEN Sidewinder
SteriPEN is a company that has built its reputation on providing products that ensure hikers, backpackers, and travelers safe drinking water no matter where they go. Their products, including the SteriPEN Traveler, which we reviewed here, use ultraviolet (UV) light to kill off 99.9% of all bacteria, viruses, protozoa, and other harmful elements that can find their way into our water. But most of their purifiers are powered by batteries, which can be difficult to come by when traveling through remote areas, and have a penchant for going dead when you need them the most. The company has found a way around that however, in the form of the Sidewinder, a purification system that is powered by a hand crank, and never requires batteries of any kind.
The first thing you’ll notice when you remove the Sidewinder from its box is that it is large, especially when compared to SteriPEN’s other products. That is due in part to the fact that it comes with a 32 oz (1 liter) BPA-free bottle, but the hand crank system is not especially small either. Prior to beginning the purification process, the bottle is filled with water. and then clicked into position on the Sidewinder itself, with the UV light completely immersed in the water. The entire unit is then flipped over, and you’re all set to begin making clean drinking water.
