This portable water bottle offers a bright solution for sterilizing water on the go.

Portable beverage containers come in all shapes and sizes. Their proliferation has been for good reasons: they are efficient, economical, and easy to use. Specialized containers exist for coffee, smoothies and water, with each variety having its own set of capabilities. Usually though, they don't come with a built-in light.

Designed for the great outdoors, the CamelBak All Clear is UV-C portable water bottle that treats water from a variety from a variety of sources. The ultraviolet light interacts with microorganisms, destroying their DNA, which renders them harmless. To use, the 0.75-liter bottle is filled at a stream, faucet or spigot, and then capped. A button on the lid initiates the process which involves 60 seconds of illumination while the user agitates the bottle for necessary exposure. After the countdown, the LED screen gives the all clear and the water is safe to drink.

Featuring a rechargeable (via USB) lithium ion battery pack, the water bottle holds a rather hefty charge. Capable of disinfecting over 80 cycles of water per charge, the bottle can be used multiple times daily for weeks without requiring a recharge. A prescreen filter is also available, which allows the bottle to be filled in nature without collecting any detritus in the container. The bulb and the battery are both designed to work for 10,000 cycles, so while the bottle may have a price tag of just under $100, its longevity could very well be worth it.
