The MB-N11 dust- and drip-resistant power battery pack boasts a shutter-release button and controls for vertical shooting. With the camera oriented vertically, this power battery pack also gives you a stable grip. If you’re on a long shoot, you can hot-swap batteries without losing power and supply power to the camera via USB. If you’re shooting video on a rig, or shooting remotely, the power battery pack frees up the camera’s USB port for communicating with external gear. This pack also features a USB-C port, which lets you charge two batteries consecutively while the pack is disconnected from the camera.
