This D-Tap to Sony a7S III NP-FZ100 Dummy Battery Cable allows you to power the Sony a7S III series cameras from any power source with a D-Tap input. When relaxed, the cable is 16" long and can be easily managed, and it stretches to 36" long when you need the additional length. It supports an input voltage range of 8 to 17V, and it outputs a power-regulated 8V. The power regulator is neatly tucked away in the dummy battery, so it doesn't interfere with the cable.

For Sony Alpha a1, a9 II, a9, a7R IV, a7R III, a7 III, a7 IV, a7S III and a6600 Cameras.
