Final Thoughts
The Nitecore NB Air is built for weekend trips and fast-and-light setups where every gram matters. One port, no frills, just reliable backup power in a waterproof carbon fiber shell. If you need multi-device charging or longer expeditions, look at the NB10000 — but for overnighters and day missions, the NB Air hits the sweet spot.
