The Nitecore NB Plus Power Bank is a slim and lightweight portable charger with a 10,000 mAh lithium-ion battery capacity. With compact dimensions and rounded corners for increased durability, it weighs only 155 grams, making it particularly portable for outdoor activities. This power bank features an IPX-7 water protection certification, safeguarding it against immersion in water. Constructed with carbon fiber panels and a composite anti-torsion structure developed by Nitecore, it offers reliable performance and resistance to shocks when carried in bags or backpacks. The device provides a maximum output power of 22.5 W through its USB-C and USB-A ports, which can be used simultaneously to charge multiple devices. The USB-C port supports QC 3.0 fast charging technology. Input charging occurs via the USB-C port with a maximum of 18 W. This output power is sufficient to charge an iPhone 16 Pro approximately 1.6 times on a full battery. A low current mode is available for efficient charging of small devices like wireless headphones. Safety features include real-time monitoring by a built-in microcontroller unit (MCU) with protection against overcharging, short circuits, deep discharge, overvoltage, and overheating. The power bank is approved for air transport with a rated power under 100 Wh. Technical specifications include input via USB-C at 5 V/3 A or 9 V/2 A (maximum 18 W), output via USB-C at 5 V/3 A, 9 V/2.22 A, 12 V/1.68 A, or 10 V/2.25 A (maximum 22.5 W), and output via USB-A at 5 V/3 A, 9 V/2 A, 12 V/1.5 A, or 10 V/2.25 A (maximum 22.5 W). When both ports are used simultaneously, the maximum output power is 5 V/3 A (15 W). In a black finish, this power bank combines practical design with robust construction for everyday and outdoor use.
