Nitecore NB Air Power Bank | 5000 mAh | 89 g | IPX7

The NB Air is one of the lightest 5,000 mAh power banks on the market: 89 g, just 9.7 mm thin and smaller than a smartphone. The carbon fibre frame with composite anti-torsion structure offers high rigidity at minimal weight. It also features IPX7 water resistance, 18 W fast charging via USB-C with PD & QC 3.0, automatic low-current device detection, and airline approval – all in one device.

The NB Air charges all devices with a USB-C port: smartphones, tablets, cameras, GPS devices, and Nitecore headlamps and torches. Thanks to the automatic low-current mode, it is also compatible with low-draw devices such as smartwatches, wireless headphones, and fitness trackers – without any manual adjustment.

Yes. The NB Air supports Quick Charge 3.0 (QC 3.0) and Power Delivery (PD) with up to 18 W output. The same USB-C port also serves as the input for recharging the power bank itself – likewise up to 18 W. With a 9V/2A adapter, the NB Air is fully charged in approximately 1 hour 42 minutes.

Yes. The NB Air is IPX7 certified and withstands submersion up to 1 metre depth for 30 minutes – without a protective cover on the USB-C port. Nitecore achieves this protection through an internally reinforced sealing technology that also protects the electronics inside. Rain, splashing water, and brief submersion cause no damage.

Yes. At 19.4 Wh, the NB Air is well below the international aviation limit of 100 Wh and meets the UN38.3 standard. It is approved as carry-on luggage on all commercial flights worldwide. Like all lithium-ion batteries, it must not be transported in checked baggage.

A brief touch of the touch button activates the four blue LED indicators: 4 bars = 75–100 %, 3 bars = 50–75 %, 2 bars = 25–50 %, 1 bar = 10–25 %, 1 flashing bar = below 10 %. The touch button responds to touch only and cannot be accidentally triggered in a backpack.

Yes, the NB Air intentionally features only one USB-C port, which serves as both input and output. This is what enables the extremely low weight of 89 g. For most use cases – trail running, day trips, travel, or EDC – one port is perfectly sufficient. Those who need to charge multiple devices simultaneously will find the NB Plus (10,000 mAh, USB-C + USB-A) a more powerful alternative.

The usable rated energy of the NB Air is 3,300 mAh at 5 V. A modern smartphone with a 4,000–5,000 mAh battery can be fully charged once, or charged from empty to around 80 % once. For smaller devices such as smartwatches, earbuds, or GPS trackers, the capacity is sufficient for several charge cycles.

Competition-Grade refers to Nitecore power banks developed specifically for competitive and extreme sports – such as ultramarathons, long-distance cycling races, or multi-day trekking tours. The focus is on absolute lightweight construction, robust build quality, water resistance, and compact dimensions that fit easily into running vests, hip belts, or backpack pockets.

Nitecore provides a manufacturer's warranty on the NB Air. In addition, the statutory warranty of 2 years from the date of purchase applies in Switzerland. At Swiss-Sale.ch you benefit from local support and straightforward warranty processing.
