Kenable DC Power Extension Lead Cable - 3M

This cable uses a 2.1mm DC barrel connector. The outer diameter is 5.5mm and the inner diameter is 2.1mm.

Yes, as long as the power adapter has a 2.1mm DC plug and its amperage rating does not exceed 6.25A, it is compatible with this extension cable. The cable itself does not regulate voltage, it simply extends the connection.

The cable supports a maximum power of 75VA, which translates to 12V at 6.25A. Ensure your power supply does not exceed these ratings.

While the cable is designed for DC power, its suitability for sensitive digital audio equipment depends on the specific requirements of the audio device. For standard CCTV and similar electronics, it is ideal. Always check your device's power specifications.

While technically possible, cutting and re-terminating the cable may compromise its integrity and is not recommended. The moulded ends are designed for secure, long-term connections. Attempting to modify the cable may void any warranty and could lead to unreliable connections or power issues.

This cable is a passive extension and will maintain the polarity of the original power adapter. Most CCTV equipment uses center-positive polarity, but it's essential to verify your device's requirements.

Ensure the power adapter's plug is fully and securely inserted into the extension cable's socket. Verify the extension cable's plug is securely inserted into the device. Check that the power adapter is functioning correctly by connecting it directly to the device (if possible). Confirm the power adapter's output (Volts/Amps) does not exceed the cable's rating (12V/6.25A).

Check all connection points for looseness or debris. Ensure the cable is not under strain or being pulled. Inspect the cable for any visible damage. The issue might stem from the power adapter itself or the device; test with a different, known-good power adapter if possible.

Verify that your device requires a 2.1mm DC barrel connector. This cable is specifically designed for 2.1mm plugs/sockets. If your device uses a different size (e.g., 5.5mm x 2.5mm), this cable will not be compatible.
