SteriPEN Sidewinder

Crank this device by hand to rid yourself of the burden of batteries that quickly run out and require continuous charging or replacement. The ideal water purification system for camper's and emergency preppers. Fully portable and extremely effective in destroying waterborne pathogens commonly found in dirty drinking water. It's very simple to use, in less than 2 minutes you can fully purify a full liter of water. The battery-free device is eco-friendly and can save thousands of plastic water bottles from polluting our environment.
