Key specs
- Connector type: DC 2.1mm male plug + female jack, sold as a pair
- Barrel size: 5.5mm outer diameter / 2.1mm inner diameter

- Rated for: 12V DC circuits
Where this fits on a job
Use this pair to re-terminate a cut power lead, join two lengths of cable to extend run distance, or replace a damaged plug or socket without swapping the whole cable. The 5.5mm/2.1mm barrel size is the interface used on cameras, DVRs, NVRs and LED drivers built to that standard — check the existing barrel on site before cutting in, since not every 12V device uses this size.
Compatibility check
Confirm the camera or PSU barrel matches 5.5mm OD / 2.1mm ID before ordering — SOURCE does not specify polarity marking, so verify centre-pin polarity (tip positive or negative) against the existing plug when re-terminating, rather than assuming.
What's in the pack
One male plug, one female jack — a complete plug-and-socket set for building or repairing a single power connection point.
