Hydro Photon SteriPEN Adventurer Handheld Ultraviolet Water Purifier w/ Solar Charger

Hydro Photon SteriPEN Adventurer Handheld Ultraviolet Water Purifier w/ Solar Charger Black/Yellow One Size. The SteriPEN Adventurer Handheld Ultraviolet Water Purifier uses UV light instead of chemicals to kill waterborne microbes, making it ideal for international, off-the-grid travel or lightweight, high-altitude expeditions. Hold the SteriPEN in your water, press the button, and gently agitate the water for full purification. The Adventurer features a smaller size than the original SteriPEN, as well as a carrying case with a solar panel for charging on the go. Depending on solar conditions, a full recharge takes between two and five days. The Adventurer's two CR123 lithium batteries can also be recharged in a few hours with the included 110V/240V adapter. The SteriPEN works best on clear running streams, questionable municipal water, and other sediment-free sources.
