The Panasonic DMW-DCC16 DC Coupler allows you to power the camera even when tethering it with your workstation. You can use the coupler with the LUMIX S1 and S1R cameras. It passes the AC power to the camera directly, eliminating the need of the rechargeable Li-ion battery. The coupler has an AC power terminal for the AC adapter that came with the camera. You can tether the camera via the USB Type-C on the DMW-DCC16 coupler.
