The Nikon MB-N12 is a vertical multi-battery grip specifically designed for the Z8 mirrorless camera. It provides extra power and a comfortable grip when shooting in a vertical orientation. Its design includes a secondary shutter, control selector, and a power button for intuitive control.

The MB-N12 supports two EN-EL15 type batteries, offering approximately 1.8 times the battery life compared to the camera's single battery. One of the batteries can be swapped out for on-the-go switching.

The grip features a USB-C port for connecting to an external power source, allowing charging via the EH-7p or EH-8p, as well as connecting the camera to other equipment. The batteries can be charged even when not connected to the camera.
