Nitecore NB10000 Gen 4
The NB10000 Gen4 is an ultralight power bank designed for hikers, travelers, and anyone on the go who demands reliable power without the extra weight. With a 10,000 mAh capacity and weighing just 143 grams, it delivers plenty of energy for long trips, daily use, or extended adventures, all while staying compact and ultralight.
This fourth-generation model builds on the popularity of the original NB10000, now even lighter and sleeker. Its slim, streamlined design slips easily into your pack or pocket, and its IPX7 water-resistant rating ensures it can handle rain, spills, and damp conditions.
Equipped with two USB-C ports, the Gen4 supports up to 22.5 W fast charging, allowing efficient power delivery to modern devices. You can even charge your devices while the power bank itself is charging. Eco Mode limits the charging power making it possible to charge devices sush as smart watches or earbuds. The included USB-C cable stays neatly in place with an innovative tether system for convenience on the move. Illuminated ports clearly show charging and battery status in low-light conditions, and the Knock to Wake feature activates the device with a simple tap. RGB lighting makes it easy to locate ports in the dark.
