SmallRig CB75 Camera Base Battery

Power your rig from beneath the camera and keep your footprint clean. The SmallRig CB75 Camera Base Battery bolts directly to your camera via two 1/4"-20 screws and adds a high-capacity 20,000mAh / 73.8Wh power source with an OLED status screen—no extra bricks or dangling cables. Two USB-C ports (up to 65W PD), two D-Tap I/O, and a DC barrel output cover bodies, monitors, wireless, and more. It fast-charges to full in about 2 hours, and can run, for example, a Canon R5 Mark II for 6+ hours or a Sony a7 IV for 7+ hours while recording 4K.

• Low-profile base battery; mounts directly to the camera
