Nitecore NB20000 Gen3 Power Bank, 20,000 mAh, 22.5 W

The Nitecore NB20000 Gen3 is a high-capacity, lightweight and durable power bank designed for hunting, hiking, camping, travelling and everyday use. With a 20,000 mAh capacity and a weight of just 291 grams, it provides a practical portable power solution when access to electricity is limited.

Its carbon-fibre-reinforced polymer housing combines low weight with excellent durability. The IPX5 water-resistance rating protects the power bank against water jets and rain, making it suitable for outdoor activities in changing weather conditions.

Two USB-C ports allow simultaneous charging of two devices. With up to 22.5 W fast charging and support for multiple charging protocols, the NB20000 Gen3 can efficiently charge compatible smartphones, GPS devices, headlamps, cameras and other USB-powered electronics.

The power bank also supports pass-through charging, allowing it to supply power to a connected device while being recharged. A four-level LED indicator provides a quick overview of the remaining battery capacity.

With a 72 Wh energy capacity, the NB20000 Gen3 is below the standard 100 Wh airline battery limit and is generally suitable for carry-on luggage, subject to airline regulations.
