Performance in the Wild
What makes the NB10000 Gen 2 such a standout for outdoor tech users is its remarkable balance between weight, power, and durability. In backcountry conditions where every ounce matters, this power bank shines. It weighs less than most smartphones, yet it still has enough juice to keep your essential devices running for multiple days off-grid.
We tested the NB10000 in high-humidity conditions and found it to be resilient against light rain and sweat. The new side-mounted power indicator is a surprisingly helpful upgrade, allowing you to check the charge status without unplugging your gear. Charging speeds were consistent — the USB-C port delivered fast charging to an iPhone 15 and GoPro Hero 11 with no drop-offs, while the USB-A port handled headlamp and smartwatch duty with ease.
The App Experience
There’s no app here — and that’s a good thing. The NB10000 Gen 2 keeps things simple and dependable. It’s plug-and-play, which is exactly what you want in a survival or backcountry context.

The Nitecore NB10000 Gen 2 is one of the smartest gear upgrades you can make if you spend serious time outdoors. Its featherweight build and practical feature set make it the perfect companion for off-grid adventures where space and weight are at a premium. There are more powerful banks out there, but none this compact and capable. If you’re looking for a “set it and forget it” charger that can keep up with your backcountry lifestyle, the NB10000 belongs in your kit.
