What you get

Two black DC power extension cables, each 10 ft long, with 5.5 mm outer and 2.1 mm inner diameter barrel connectors. The male-to-female design lets you extend the reach of any device that uses this standard plug.

Build and daily use

Heavy-duty insulation handles indoor and outdoor routing for security cameras, LED strips, routers, DVRs and similar low-voltage gear. The 5.5 mm by 2.1 mm jack fits snugly, reducing accidental disconnects when cables are tucked along walls or ceilings.

Check before ordering

Confirm your equipment runs on 24 V, 12 V, 9 V, 6 V or 5 V DC and accepts a 5.5 mm x 2.1 mm barrel plug. Devices with a different connector size or a proprietary power input will not work with these cables.

Questions about this item

What voltage does the 5.5 mm x 2.1 mm barrel connector support in practice?

The cable is rated for 24 V, 12 V, 9 V, 6 V and 5 V DC equipment, so it carries whatever voltage the connected power supply delivers within that range.

What clearance does the 5.5 mm outer-diameter plug need to fit?

The male barrel plug measures 5.5 mm outer diameter and 2.1 mm inner diameter, so the mating jack must accept those exact dimensions.

How do I connect the male-to-female extension without reversing polarity?

Plug the male end into the power supply and the female end into the device; the barrel geometry only fits one way, preventing a reversed connection.
