DC 7.4mm x 5.0mm Male Power Extension Cord

This 1.8m power extension cord features a DC 7.4mm x 5.0mm male plug on one end and stripped, tinned wires on the other for direct terminal connection. It is built with 18AWG pure copper conductors and a flame-retardant PVC jacket for durability. A ferrite magnetic ring is fitted to suppress high-frequency noise and interference. The cord suits installers extending CCTV, DVR, or camera power runs where the device has a matching 7.4mm x 5.0mm female jack.

Installers needing a 1.8m reach

The cable suits security technicians and DIY users who need to bridge a gap between a power supply and a device equipped with the specific 7.4mm outer and 5.0mm inner diameter jack. The pre-tinned leads simplify wiring into screw terminals or solder joints without extra preparation. Buyers whose equipment uses a different barrel size, a locking connector, or a polarised multi-pin plug cannot use this cord and should look for a lead matching their exact port specification.

7.4mm outer and 5.0mm inner diameter male barrel

The single specification that decides compatibility is the DC plug geometry: a male barrel measuring 7.4mm outside diameter and 5.0mm inside diameter. Only devices with a matching female jack will accept this connector. Verify the port on your camera, DVR, or power adapter matches these dimensions before ordering, as no other connector type or size is supported by this cable.

Questions about this item

Will the 18AWG copper wire need replacement under normal use?

The 18AWG pure copper conductors are rated for continuous operation and the flame-retardant PVC jacket resists aging and oxidation, so the cord itself should not require replacement unless physically damaged.

What limits the current I can draw through the 7.4mm x 5.0mm plug continuously?

The 18AWG copper wire and the 7.4mm x 5.0mm male barrel connector together set the practical current limit; exceeding the wire gauge rating will cause heating before the magnetic ring or insulation becomes a factor.

Does the magnetic ring or the 1.8m cable generate noticeable heat or noise when powered all day?

The ferrite magnetic ring is a passive suppressor and produces no heat or sound; the 18AWG copper cable runs cool at its rated load and the PVC insulation remains stable during extended operation.
