DC Power Extension Cord 2-Pack

This Fancasee extension cord adds three feet of reach to any 5.5 mm by 2.1 mm barrel jack. The 18 AWG pure-copper conductors keep resistance low across the full run. Each cable is UL listed and terminated with a male-to-female barrel connector. The white jacket suits indoor and outdoor installations.

For CCTV, LED strips and low-voltage gear

Installers extending power to security cameras, DVRs, LED lighting, routers or solar-battery equipment will find the plug-and-play fit immediate. Buyers who need a different barrel diameter or a longer single run should look at other options. The two-pack only covers two separate devices or one device with a spare.

5.5 mm by 2.1 mm barrel size

The connector’s 5.5 mm outer diameter and 2.1 mm inner diameter are the sole specification that determines whether the cord mates with your equipment. Verify the jack on your power supply and device match these dimensions before ordering.

Questions about this item

How much reach does the 3 ft length add between a 12 V camera supply and the device?

The 3 ft extension lets you place a 12 V security camera or LED strip up to three feet farther from the power adapter without voltage drop concerns on the 18 AWG copper conductors.

What does the 5.5 mm by 2.1 mm barrel spec guarantee for a 24 V DVR connection?

The 5.5 mm outer and 2.1 mm inner diameters match the standard coaxial plug on most 24 V DVR and router power bricks, ensuring a secure centre-positive fit.

What clearance is needed behind a panel for the moulded 5.5 mm plug to seat fully?

The straight male barrel requires enough rear clearance for the plug body to insert completely into the female jack; allow space for the moulded housing plus cable bend radius.
