The Sony DC-C1 DC Coupler is a “dummy battery” that replaces either an NP-FW50 or an NP-FZ100 battery inside your camera and connects to an AC outlet for continuous wall power – a great feature for long indoor shoots. This rental is just for the coupler. A USB PD AC wall adapter and USB-C cable are not included. The coupler is attached to a 5.2’ cable, allowing you some movement even while tethered to an outlet.
