Nitecore NB Plus
10,000 mAh in 155 g – Competition-grade power bank for outdoor & everyday use
10,000 mAh in 155 g – the NB Plus from Nitecore
The Nitecore NB Plus is an ultra-light, slim power bank for outdoor enthusiasts, trail runners, travelers, and anyone who needs maximum capacity with minimum weight. With 10,000 mAh, 22.5 W output power, a carbon fiber casing on both sides and a thickness of only 11.7 mm, the NB Plus is slimmer than most smartphones – and IPX7 waterproof and airworthy. USB-C and USB-A are available simultaneously, so two devices can be charged at the same time.
Competition-grade · Carbon fiber technology
Anti-torsion structure – lightweight, flat & break-resistant
The NB Plus case consists of double-sided carbon fiber plates with a lightweight composite frame in an ultra-thin design. The anti-torsion structure prevents twisting under mechanical stress – ideal for use in tight running pockets, backpack hips, or jacket pockets. Rounded corners absorb shocks and reliably protect the case and its contents. The result is a power bank that is barely noticeable in weight but reliably delivers power in any weather and in any situation.
Dual port – USB-C and USB-A with fast charging function
The NB Plus has a USB-C port (input & output) and a USB-A port (output only). Both ports support fast charging with up to 22.5 W output power – compatible with Quick Charge (QC) and Power Delivery (PD). The USB-C port accepts up to 18 W of power from the power bank itself. When both ports are used simultaneously, the total power output is a maximum of 15 W. The charge level is displayed at the touch of a button via four blue LED indicators.
IPX7 – internally sealed for maximum protection
The NB Plus is IPX7 certified and can withstand submersion in up to 1 meter of water for 30 minutes. Nitecore uses internally reinforced sealing technology that protects the power bank from the inside and outside – not only the exterior, but also the internal electronics. Rain, splashes, sweat, and brief submersion are therefore no problem. The rounded corners of the housing also absorb shocks and protect the power bank in the event of a fall.
Airline-approved for worldwide travel
With a nominal capacity of 38.5 Wh, the NB Plus is well below the international aviation limit of 100 Wh and is therefore approved as hand luggage on all scheduled flights worldwide. It complies with the UN38.3 standard for the air transport of lithium-ion batteries. Whether you're on a business trip, running an ultramarathon, or trekking for several days, the NB Plus fits in any jacket pocket and is always ready for use.

Frequently Asked Questions about the Nitecore NB Plus Power Bank
What makes the Nitecore NB Plus special?
The NB Plus combines 10,000 mAh capacity with a weight of only 155 g and a thickness of 11.7 mm – thinner than most smartphones. Dual-sided carbon fibre panels with an anti-torsion frame provide high rigidity at minimal weight. The power bank is IPX7 waterproof, airline approved, and supports fast charging via USB-C and USB-A with up to 22.5 W.
Which devices can I charge with the NB Plus?
The NB Plus charges all devices with a USB-C or USB-A port: smartphones, tablets, headphones, cameras, GPS devices, Nitecore headlamps and torches, and other compatible electronics. Both ports can be used simultaneously, with total output limited to 15 W in this case.
Does the NB Plus support fast charging?
Yes. The NB Plus supports Quick Charge (QC) and Power Delivery (PD) with up to 22.5 W output via both ports. The USB-C port accepts up to 18 W for recharging the power bank itself. When both ports are used simultaneously, the total output is limited to 15 W.
Is the NB Plus airline approved?
Yes. At 38.5 Wh, the NB Plus 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.
Is the NB Plus waterproof?
Yes. The NB Plus is IPX7 certified and withstands submersion up to 1 metre depth for 30 minutes. Nitecore uses an internally reinforced sealing technology that protects not only the housing but also the internal electronics. Rain, splashing water, and brief submersion are no problem.
How do I check the battery level of the NB Plus?
A short press of the power button activates the four blue LED indicators: 4 bars = 75–100 %, 3 bars = 50–75 %, 2 bars = 25–50 %, 1 bar = below 25 %. The display turns off automatically after a few seconds.
Can I charge and discharge the NB Plus simultaneously (pass-through)?
The NB Plus does not support simultaneous pass-through charging. The device can either be charged or discharged, but not both at the same time via the same USB-C port. This protects the battery cells and extends the lifespan of the power bank.
How long does it take to charge the NB Plus?
With an 18 W USB-C adapter (5V/3A or 9V/2A), charging the NB Plus takes approximately 2 to 3 hours. A USB-C charging cable is included. A PD- or QC-compatible adapter is recommended for optimal charging speed.
What does Competition-Grade mean for the NB Plus?
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. These models are characterised by exceptionally low weight, robust construction, water resistance, and compact dimensions that fit easily into running vests, hip belts, or backpack pockets.
What warranty applies to the Nitecore NB Plus?
Nitecore provides a manufacturer's warranty on the NB Plus. 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.
The Nitecore NB Plus user manual covers all functions of the power bank: charging via USB-C, using the USB-A output, checking the battery level at the press of a button, and guidance on safe storage and care. The manual is also available as a download on the official Nitecore website.
