If the product is not in stock, it will be delivered within the stated delivery time.

A lightweight and compact carbon fiber reinforced power bank designed for outdoor adventures and everyday use. With a high-capacity 20,000 mAh (72 Wh) battery, it is an excellent choice for hiking, trekking, travel, and other situations where reliable portable power is essential. Thanks to its nominal energy rating of less than 100 Wh, the NB20000 Gen3 is also approved for air travel. The power bank features two USB-C ports, both of which can be used for charging the device itself as well as charging external devices.

The Nitecore NB20000 Gen3 is the latest generation of Nitecore’s highest-capacity NB Series power bank. Compared to its predecessor, the Gen3 version is lighter and more compact, making it even easier to carry in a backpack, pocket, or travel bag. Weighing only 291 grams, it adds minimal weight to your gear while providing substantial power capacity.

According to the manufacturer, the battery capacity is sufficient to recharge an iPhone 15 Pro nearly four times or an iPad Pro approximately 1.5 times. The NB20000 Gen3 complies with the UN38.3 transportation standard and can be carried on commercial flights, as its rated capacity remains below the 100 Wh airline limit. A USB-C to USB-A adapter is included, allowing compatibility with devices that use traditional USB-A charging connections.

The carbon fiber reinforced construction, inspired by materials commonly used in the aerospace and automotive industries, provides an excellent balance of strength, durability, and low weight. The housing helps protect the internal components and battery cells from impacts while maintaining an exceptionally lightweight design. The integrated high-performance 18650 lithium-ion battery delivers ample capacity for charging multiple devices or recharging the same device several times.

Battery status is indicated by four blue LED indicators:

4 LEDs: approximately 100% charge
3 LEDs: approximately 75% charge
2 LEDs: approximately 50% charge
1 LED: approximately 25% charge
Flashing LED: battery nearly depleted

For safe operation, the power bank incorporates multiple protection systems, including overcurrent, short-circuit, overcharge, over-discharge, overvoltage, and thermal protection.

The NB20000 Gen3 is an excellent choice for hikers, backpackers, travelers, and outdoor enthusiasts who require a reliable high-capacity power source for smartphones, GPS devices, cameras, and other electronics. It also serves as a valuable addition to emergency preparedness and backup power kits.
