The SteriPen Ultralight is a 3-ounce pen-style UV water purifier built for thru-hikers, ultralight backpackers, and travelers who count every gram. The compact pen-style form factor drops into any pack pocket, vest pouch, or hydration bottle. Water-activated operation starts on contact so you cannot leave it running or forget to trigger it - no button to forget, no accidental battery drain inside your pack. UV-C light purifies clear water in 90 seconds (1L) or under a minute (0.5L) without chemicals or taste change. USB rechargeable - no more hunting for backpacking batteries in small mountain towns. A single charge delivers approximately 20 treatments, enough for a full multi-day solo trip. The 8,000-treatment UV lamp delivers years of reliable use. Best used with clear water sources; pre-filter cloudy water first for full effectiveness.

### ⭐ Bad batteries!
*by D***. on February 14, 2026*

BAD BATTERY, NO DIRECTIONS, OVER $100. REALLY? Katadyn SteriPen Ultralight UV Water Purifier. What could possibly make this device worth over $100.? Bad internal battery! Hardly no directions! I know lithium batteries, and they go bad if you do not use them. I have several power stations, and several other products that use lithium. So this has been my experience with this and other products. Better to buy the products with batteries, because you have more control, $100.? Dennis M.
