Running out of battery during a long video shoot, live stream, or time-lapse session is frustrating. Fortunately, there’s a simple solution: using a dummy battery (also known as a DC coupler).
In this guide, you’ll learn how to power your DSLR directly from an AC outlet using a dummy battery setup — perfect for uninterrupted sessions.
What Is a DSLR Dummy Battery (DC Coupler)?

Dummy batteries are lifesavers for:
- Live streaming

- Time-lapse photography
- Zoom or Webinar calls with DSLR webcams
