The SHAPE J-Box Camera Power & Charger Kit for the Sony FX3, a7R III, a7 III, a7S III, and a7 IV cameras is composed of a J-Box power and charger. It features a small-size, lightweight V-mount battery plate with safe lock. The J-Box has five outputs including D-Tap and 5, 8, 12, and 16.8V ports, as well as USB 5V. It supports up to 100W power consumption from the device and includes a 15mm rod mount bracket with locking and angle adjustment system.
There are threaded holes at the back of the plate for mounting on a cheese plate and LED indicators for power. When the J-Box is plugged in you can safely disconnect and reconnect a separately available battery without powering down your rig. A 110 to 240V power supply, an AC power cable, an 8/12V cable output connector, a camera cable connector, and a removable Delta plate are included.
