DC Power Extension Cable

The Unique-Bargains power extension cord adds 6.56ft of reach to any device that uses a 2.1mm x 5.5mm barrel connector. It suits installers who need to route DC power to cameras, LED lighting, routers or sensors without moving the original power supply. The male-to-female layout simply plugs in line with the existing adapter.

Build and Connector Details

The cable uses copper conductors rated for a 10000 bend lifespan, reducing failure risk on runs that see occasional movement or vibration. Black insulation covers the full 2M length, and the 5.5mm outer by 2.1mm inner dimensions match the common centre-positive coaxial standard found on many CCTV, printer and monitor power bricks. Operating range spans 58 to 149 degrees Fahrenheit.

Compatibility Limits

This cord only works with equipment that already accepts a 2.1mm x 5.5mm plug; it cannot adapt other barrel sizes or voltage levels. Polarity and voltage must match the connected supply and device exactly, as the cable provides no conversion or regulation. Buyers needing a different inner diameter, outer diameter or locking connector must select a different lead.

Questions about this item

What does the 2.1 mm × 5.5 mm barrel connector limit this cable to?

It only fits devices that accept a 2.1 mm inner and 5.5 mm outer DC plug, so equipment with a different barrel size will not connect.

What physical space is required to route the 6.56 ft cable?

The cable is 6.56 ft long with a black PVC jacket; allow enough slack for the full run plus bend radius so the copper conductors are not kinked.

How is the extension installed, and what step is often missed?

Plug the male barrel into the power supply and the female barrel into the device, then verify the connector size matches 2.1 mm × 5.5 mm before powering on.
