There are solar chargers that work nicely on the trail, but those require sun. If you are without that for a few days, you might get skunked. Even then, with a full charge, we've experienced the sad face for no reason, which left us frustrated and without clean water. Luckily we had a chemical treatment backup. Like everything electrical, it's not the most reliable in the backcountry and more suited for situations that won't leave you wondering if you'll survive or not.
This unit counts down your purification time. It takes 90 seconds and some swirling to purify one liter of water. There is also the option to do a half-liter which takes half the time. Of the SteriPEN models, it's the heaviest, but it's much lighter than pump filters that treat viruses. The profile is narrow, which fits nicely into a backpacking pack or even a running pack.
The Ultra is very simple to use. Turn it on, place it in your bottle. Water retrieval depends on your storage container. If you are taking from a water source with lots of sediment, make sure to pre-filter your water or consider a filter instead. Treatment is also easy. Wait for 90 seconds per liter purified.
Swirl it around. When you see the smiley face, your water is ready to drink! If you see a frowny face, it means either your battery isn't working, or something is wrong. It is pricy. Given that it's not super reliable, even though it does remove viruses and other stuff, it's not our first recommendation for most things. Joined Dec 31, Messages My wife and I switched to using a steripen last year.
We chose the adventurer model. Has so far worked flawlessly for about 30 days of two person use. Zero regrets on our choice. But I did buy the new model for doing larger quantities, Quantum or something like that, but haven't used it yet, bought it after elk season.

I got rid of everything battery powered but want to run a steri pen this year so don't wanna throw a battery powered thing back into my pack Joined Dec 7, Messages I run the Opti Adventurer.
Has worked flawlessly for 2 years now. Others have had issues with them, but I love mine. COlineman78 Senior Member. The Adventurer Green and Black is a gigantic piece of shit that will not work with high mountain spring and runoff that has low mineral content.
The sensor that detects when it is in the water is crap; I've gotten it to work at high altitude by adding salt to the water to increase conductivity.
The Ultra is the best rechargeable option, but is also expensive. COlineman78 said:. A variety of microorganisms, such as bacteria, viruses and protozoa, which often come from human and animal waste that has entered the water, can cause serious health risks.
Water that may cause concern can be easily filtered through effective water purification systems. SteriPEN is a handheld water filtration system that uses ultraviolet light to make drinking water safe. Leading bottled manufacturers use the same type of technology, along with major cities in the United States, Europe and Asia. It is a small version of the UV-light technologies used in municipal water purification plants around the world.
Feather light 3. In short, I flat-out love this thing. The minimal weight 3. Just make sure you have a spare set of batteries! We invite you to visit our comprehensive water filter and purification guide , drink in our accumulated knowledge, and see why we recommend the SteriPEN Adventurer Opti below.
Which meant I had to get rid of the water filter beast in my kit. It was love at first sight. I picked it up and laughed out loud! Then I experimented with packing options, placing the sleek, neoprene case in a few different locations. I realized it would fit anywhere in my pack, and ultimately decided to make its home my right hip belt pouch for easy access while on the trail.
When my water-bottles were finally spent, I stopped at a rivulet that bisected the trail and pulled out my SteriPEN. The moment of truth had arrived. I dunked my bottle, filling it to the brim. Per the instructions, I swirled it in a circular motion for 90 seconds really, until the UV light turns off. Then I waited for a breathless second, and rejoiced when the indicator light flashed green — letting me know the water was safe to drink if it flashes red you need to treat it again.
Then I drank the luscious mountain water until my belly was full and my mood lifted. While the Adventurer Opti stole my heart on this first trip, I have been continuously using it since then and have grown even fonder of it for a few reasons. First, the CR batteries last forever.
