DC 5.5×2.1 mm male-to-male extension cable

This pair of 78-inch cords extends the reach of 12 V DC power supplies that use a 5.5 mm by 2.1 mm barrel connector. Each cable is built with 18 AWG oxygen-free copper conductors inside a frost-resistant, pull-resistant PVC jacket rated for continuous use up to 36 V. The male-to-male design suits CCTV cameras, LED strips, routers, printers and similar low-voltage gear.

Current capacity and voltage headroom

The assembly is specified for 1 A to 10 A loads across a 1 V to 36 V range, with 12 V and 24 V being the most common operating points. At the top end of that current band the 18 AWG conductors will warm noticeably, so sustained draws near 10 A should be kept as short as practical. The PVC insulation remains flexible down to freezing temperatures but is not rated for high-voltage AC mains.

Barrel-connector interface limits

The 5.5 mm × 2.1 mm centre-positive barrel is a de-facto standard for 5 V–24 V DC equipment, yet pin diameter and sleeve length can vary between manufacturers. A loose or oversized mating jack will cause intermittent contact and voltage drop under load. The cable must not be used beyond its 36 V DC rating or in any AC mains circuit, and polarity must match the device requirement before connection.

Questions about this item

Will this 5.5mm x 2.1mm male-to-male cable work with my existing 12V CCTV camera and LED strip?

Yes, the 5.5x2.1mm connectors match those devices and the cable supports 12V DC with up to 10A current capacity.

How can I verify the extension is delivering stable power after connecting it?

Check that your device powers on normally and operates without voltage drop; the oxygen-free copper core and 18AWG gauge are designed for low resistance.

What comes in the package and do I need any extra adapters?

The box contains two 78-inch black male-to-male DC extension cords with 5521 connectors; no extra adapters are required if your gear uses 5.5x2.1mm ports.
