Power bank Nitecore NB20000, 20,000 mAh

The Nitecore NB20000 is a compact and light (324.5 g) power bank. The NB2000 is the largest power bank in the manufacturer's NB series, and is practical and easy to carry. Its carbon fiber reinforced structure is familiar from e.g. the aerospace and automotive industries and it is designed to achieve excellent impact resistance, which guarantees excellent protection for e.g. the device's battery cell. According to the manufacturer, this handy 20,000 mAh power bank is up to 27% lighter and 57% smaller compared to a conventional power bank, making it a great "emergency backup" for many different adventures. The NB20000 is equipped with a 20,000 mAh Li-ion battery and has a remarkable energy density of 237 mWh/g.

The Nitecore NB20000 power bank has two USB-C ports, one of which functions as an input-only port and the other as both an input and output port. The device also has two standard USB-A output ports (18 W). In addition, it supports the QC (Quick Charging) charging protocol, which guarantees extremely fast charging. According to the manufacturer, the device's capacity can charge an iPhone 12 smartphone more than six times and a MacBook Pro almost once from empty to full. Complying with the UN38.3 standard, the Nitecore NB20000 can also be taken on a flight, as the unit's rated capacity is less than 100 Wh. The device comes with a USB charging cable (USB-A -> USB-C).

The NB20000 has a four-step charging status, which shows the remaining charge with blue LED indicators. Four lights at 100%, three lights at 75%, two lights at 50%, one light at 25% and a flashing light indicate when the charge is almost used up. The device also has a low-current charging mode for more sensitive devices, such as Bluetooth headphones and smart watches. It is activated by double-clicking the device's power button. The device's over-current, short-circuit, over-charge, over-discharge, over-voltage and thermal protection functions ensure safe use.

Overall, the Nitecore NB20000 is an excellent choice for e.g. long hiking trips where a high-capacity power bank is needed to charge electronic devices such as phones, navigators, etc. It is also an excellent addition to the "emergency kit" taken on trips.
