Features: Use the battery grip to hold two batteries to greatly extend battery life. Also designed with a USB Type-C port to charge the inserted batteries without having to remove them from the grip. Recommended for time-lapse video recording and long-hour filming. When the battery grip is mounted, the camera can display its remaining battery level. Or press the CHECK button on the grip, and the two battery indicators will let you know clearly how much power is left for the two inserted batteries separately. Easy to install, the battery grip can be mounted on your camera within minutes. Firstly, put one or two EN-EL15 batteries into the grip's compartments. Next, empty your camera's battery compartment and remove the compartment door. Then, insert the battery grip into your camera's battery compartment and rotate the lock key to secure it tightly. After that, turn on both the battery grip and your camera. Users can also use the included shutter cable to connect the grip to your camera, allowing you to control your camera's shutter via the grip's shutter button, a great convenience for both vertical and horizontal shots.
