Nitecore NB10000 Gen 4 Review

The Nitecore NB10000 Gen 4 is an ultralight 10,000mAh power bank rated IPX7 waterproof, with two USB-C ports supporting up to 22.5W and a lanyard charging cable included.

This is the newer, tougher sibling to the NB10000 Gen 2 already in our catalog: same slim form factor, but bumped to a full IPX7 waterproof rating and a lanyard cable so it can clip right onto a pack.

Ports and Charging

Two USB-C ports handle both input and output at up to 22.5W each, and a lanyard charging cable is included so you can clip it to a pack or bag.

Durability

IPX7 waterproofing takes it a step past the Gen 2's carbon fiber shell, and at 143g it stays genuinely pocketable.
