5.5 mm x 2.1 mm DC Adapter Kit

Hobbyists repairing CCTV

The parts fit 5.5 mm x 2.1 mm barrel jack interfaces found on security cameras, media players and similar devices. Builders needing a different barrel diameter, a snap-in connector without soldering, or a pre-assembled cable should look elsewhere.

5.5 mm outer and 2.1 mm inner diameter specification

Compatibility depends entirely on matching this exact coaxial dimension to the device power port. Verify the measurements on the original equipment before ordering to ensure a correct fit.

Questions about this item

Does the kit include solder or tools, or only the 5.5 mm x 2.1 mm plugs and jacks?

The kit supplies five male plugs and five three-pin female PCB-mount jacks. Solder, a soldering iron, wire and any heat-shrink tubing must be sourced separately.

Should I choose the 5.5 mm x 2.1 mm size or a different diameter for my CCTV camera?

Match the adapter to the camera's existing jack. This kit only provides the 5.5 mm outer and 2.1 mm inner diameter size, so it fits devices that already use that exact barrel dimension.

Will the 5.5 mm x 2.1 mm plug carry enough current for a typical security camera?

The connector itself is a passive barrel type; its current capacity depends on the wire gauge you solder to it and the camera's power draw, not on the plug alone.
