As the new member in the NB Series product line, the NITECORE NB20000 Ultra Lightweight Carbon Fiber Energy Brick is out now. It is constructed with lightweight carbon fiber and suitable for photography, filming, hiking, camping and more.

It is recommended to select different power according to various outdoor activities. The NB5000 is for short distance trail races of less than 20 hours and the NB10000 is for long distance trail races of more than 20 hours while the NB20000 is ideal for outdoor adventures of 2-3 days. The IPX5 Rating makes it fearless of the rainy or snowy weather.

Available with two-way PD + QC output and more, the dual USB-A + USB-C multi-port output makes the charging process incredibly convenient. The 30W fast charge input enables only 2h 40min to charge 80% of its power. The max output power of 45W via the USB-C output port is available to charge laptops, tablets, portable game consoles and more. The Low Current Mode is suitable for charging low current devices including wireless headphones, wearables and more. The blue indicators can display the charging status and the power level.

Widely used in aerospace and automotive engineering, the Carbon Fiber Reinforced Polymer (CFRP) which constructs the frame features ultra light weight and high strength, designed to achieve an excellent impact resistance and ideal to protect the cell. The interwoven carbon fiber sheets are selected to stabilize the cell and guarantee a safe usage. The all black combination of the sandblasted frame and hi-tech texture offers an anti-slide grip with great comfort.

With an ultra light weight of only 324.5g (11.45oz), the NB20000 is 27% lighter and 57% smaller than conventional power banks. With a 20,000mAh built-in Li-ion battery, its energy density reaches 237mWh/g, 13% higher than conventional 18650 Li-ion batteries. When the output reaches 45W, the intelligent thermal protection module will automatically regulate its output according its working status to maintain the optimal performance and prolong the lifespan of the battery.

The NB20000 is equipped with multiple protection safeguards to be used in temperature between -10~40℃ (14~104℉). It is safe and reliable as globally insured and multiple global certifications approved. In accord with the UN38.3 Standard with a rated capacity less than 100Wh, the NB20000 is airline approved as your best worry-free power companion while on the move.
