NB20000 Gen3 power bank

The Nitecore NB20000 Gen3 power bank offers a large 20,000 mAh capacity for just 291 g. Pack this energy reserve for several days away from sockets: smartphone, GPS, head torch and watch are all covered.

An excellent capacity-to-weight ratio

Its carbon fibre casing keeps weight low without sacrificing strength, with stated 1.5 m drop resistance. It delivers around 11,220 mAh at 5 V, enough for several smartphone charges depending on model.
Compact at 11.8 x 6.9 x 2.2 cm, it resists splashes (IPX5): rain is fine, but it must not be immersed.

Two versatile USB-C ports

• 2 bidirectional USB-C ports: each recharges the power bank (18 W max) or powers a device (up to 22.5 W fast charging).
• Two devices can charge simultaneously (15 W total).
• Pass-through charging: connected to mains power, it continues powering a device through the other port (15 W max).
• Automatic detection of low-power devices such as earphones, smartwatches and GPS units.
• 4 blue indicators show remaining charge.

A USB-C to USB-A adapter is included for older cables.
