It seems like you can do anything via USB these days – even purify water. The SteriPEN Freedom is a tiny USB-based water purifier that uses an ultraviolet light to purify a 16-oz. glass of water in as little as 48 seconds. The device eliminates bacteria and viruses that cause waterborne illnesses making it a valuable tool for both the hiker and the world traveler – at least those who travel with a laptop! Unlike previous battery-driven models, the SteriPEN Freedom features a micro USB port for charging and can be used up to 40 times on a single charge.
Its overall lifespan is estimated at roughly 8,000 treatments, and best of all the device also doubles as a flashlight. It’ll be available next month for $119.
