The Nikon MB-N14 is a multi-battery vertical grip that provides both additional power and a more comfortable grip when working in the vertical shooting orientation. Its design incorporates a secondary shutter release, control dials, and a function button for more intuitive shooting control. The MB-N14 can accommodate two EN-EL15-type batteries, which provide around 1.8x longer battery life than the single in-camera battery, and one of the batteries can be hot-swapped for on-the-fly battery switching. A USB-C port is also featured for connecting to an external power source, charging via the EH-7p or EH-8p, or tethering or connecting the camera to other equipment. Also, batteries can be charged inside the grip even when it's not attached to the camera. The MB-N14 Power Battery Pack is compatible with the Z7II and Z6II mirrorless cameras.
