STREAM SL-B26 PROTECTED Li-Ion USB Battery Pack – 2600mAh Portable Power Bank

The STREAM SL-B26 is a compact Li-Ion USB battery pack built to extend the runtime of compatible rechargeable flashlights in the field. At just 1.7 oz and 2.75 inches long, this 2600mAh protected battery slides into gear bags, pack pockets, or vehicle storage without adding bulk—ideal for hunters, tactical shooters, search-and-rescue teams, and overlanders who need dependable backup power for their lighting systems.

Built with integrated safety circuitry, the SL-B26 guards against overcharge and overdischarge damage, keeping your battery healthy through repeated field use. The micro-USB charge port means you can top it up anywhere you have a standard USB charger—at basecamp, in your truck, or back at the cabin. A full charge takes about 5 hours, so overnight charging before a hunt or training session keeps you ready to go.

This is a purpose-built power solution, not a universal phone charger. The SL-B26 pairs with specific compatible rechargeable flashlight models, transforming multi-fuel lighting tools into fully rechargeable systems. If you already own one of the compatible Sightron or similarly-designed tactical and outdoor flashlights, the SL-B26 adds genuine utility—one less battery type to manage, and the confidence that your light stays bright when you need it most.
