Chase big miles without babysitting your battery. The Nitecore NB10000 Gen4 packs a dependable 10,000mAh capacity into a truly pack-friendly build—just 4.94 oz with a slim, pocketable shape that disappears into a belt pouch or shoulder pouch when every ounce counts.

Built for real trail conditions, it adds IPX7 water resistance for wet-weather confidence, plus dual USB-C ports that deliver up to 22.5W fast charging so you can top off a phone, headlamp, or GPS quickly during town stops or short breaks. Smart touches like pass-through charging, an integrated lanyard-style USB-C cable, illuminated ports, and a knock-to-wake power check keep your system simple, efficient, and ready, no fumbling, no guesswork.
