Extending the Camera Power Supply Cable
My camera is too far away from a power outlet, what can I do? How can I make the power cord on my camera longer?
You can extend the length of the camera power supply cable by getting an 3.5 mm (1/8") stereo [TRS] headphone extension cord. You can usually find a cord like this anywhere that sells consumer electronics. Any kind of headphone extension will work, as long as the male ends of the extension cable and the camera power supply match.
