4.92ft 18AWG DC power extension cord

This 4.92ft 18AWG DC power extension cord connects devices using a 5.5mm x 2.1mm male plug with lock nut to a matching female socket. It is designed for users who need to extend the reach of a 12V DC power source for CCTV cameras, LED strips, routers or similar equipment. The cable supports a maximum of 12V at 10A for up to 120W.

Lock nut connectors and 18AWG copper conductors

The male and female DC5521 connectors both feature lock nuts that prevent accidental disconnection during operation. High-quality copper wires inside the 18AWG gauge provide low resistivity and reliable conductivity. Double-layer PVC insulation adds durability, freeze resistance and high-temperature tolerance for secure, long-term installations.

Limited to 12V DC barrel-type devices

This cord only works with equipment that accepts a 5.5mm x 2.1mm barrel connector and operates at 12V, 9V, 6V, 5V or lower DC voltages. It cannot deliver power to devices requiring higher voltages, different connector sizes or AC input. The 1.5m length also restricts placement to within roughly five feet of the power source.

Questions about this item

Will the 18AWG copper conductors or the DC5521 connectors need replacement after extended use?

The 18AWG copper wires and DC5521 male-to-female connectors are built for reliable, secure connections; no periodic replacement is expected under normal operation.

What is the first limit reached when the cable runs continuously at its 120W maximum rating?

The 10A current ceiling at 12V is the primary limit; sustained loads above 120W would exceed the rated capacity of the 18AWG conductors.

How much heat or power loss should I expect from the 1.5m length during all-day operation?

The 18AWG gauge keeps resistive loss low; at the rated 10A the cable stays cool to the touch and adds negligible voltage drop over 4.92ft.
