The MB-N10 is a Multi Battery Power Pack for the Z 7 and Z 6 full frame mirrorless cameras (cameras sold separately). It is designed to add additional shooting time versus just using the battery in the camera alone. The MB-N10 may increase the length of shooting time up to 1.8x* (*CIPA standard) more than using just the camera’s battery. The MB-N10 is designed with the same weather sealing and modern design of the Z cameras and affords photographers a well-balanced feel when a long telephoto lens is on the camera.

The MB-N10 can accept two EN-EL15b or EN-EL15a/EN-EL15 rechargeable Lithium-ion batteries, each housed in its own battery compartment. For convenience, the batteries are hot-swappable, which means that you can replace one while the other continues powering the camera. This is beneficial for video, interval and time-lapse shooting. With two batteries, power is first drawn from the battery in chamber A until it is depleted, and then the unit draws power from the battery in chamber B.

Other features include battery power level displays for each battery, a socket for connectivity to a tripod and the ability to use the optional EH-7P Charging AC Adapter to charge the EN-EL15b batteries while inserted into the unit, whether its attached to the camera or not.
