Nitecore NB10000 Gen 2 Review

For ultralight backpackers who weigh every gram in their pack, the Nitecore NB10000 Gen 2 is one of the lightest 10,000mAh power banks you can buy, thanks to its carbon fiber composite shell.

At 178g, it's roughly 30-40% lighter than the plastic or aluminum-shelled banks at the same capacity, which sounds trivial until you're counting ounces across a multi-day thru-hike. It doesn't do anything fancy: no wireless charging, no display beyond LEDs, no AC outlet. It just holds 10,000mAh and weighs as little as physically possible doing it.

Why Carbon Fiber Matters Here

The carbon fiber composite shell isn't a cosmetic choice, it's meaningfully lighter than the polycarbonate or aluminum housings used on comparable-capacity banks while still being more impact-resistant than bare plastic. For thru-hikers optimizing base pack weight, this is one of the few places to shave grams without sacrificing capacity.

Comparison to Alternatives

The Anker Nano 5000mAh is lighter in absolute terms but holds half the capacity, so per-mAh the NB10000 Gen 2 is the more weight-efficient choice for multi-day trips. Against the Vtin Slim 24000mAh, which prioritizes flat carry-profile over weight, the Nitecore is the pick when grams matter more than capacity.
