Connector compatibility for CCTV and LED projects

These cables adapt a 3.5x1.35mm female socket to a 5.5x2.1mm male plug, bridging two common DC barrel sizes. Each 16cm lead lets you extend power to security cameras or LED strips without soldering. The four-piece pack covers multiple endpoints in a single installation.

Passive copper conductors with plastic housings

The internal copper wire carries current while the black plastic shells insulate the connection. No active electronics are present, so the cables add no audible noise or measurable heat during normal use. Their 30g weight per unit keeps strain on sockets minimal.

Plug directly into existing power leads

The male and female barrels mate with standard CCTV camera pigtails and LED strip drivers, requiring no tools or adapters. The short length frees up space in tight enclosures and reduces cable clutter around the camera mount. Buyers who need longer runs or different barrel diameters will need alternative cables.

Questions about this item

How do you connect the 3.5x1.35mm female end to a 5.5x2.1mm male power source without reversing polarity?

Align the centre pin of the 5.5x2.1mm male plug with the female socket and push straight in; the 16cm cable then extends the reach to the 3.5x1.35mm device.

Will the copper conductors inside the 16cm black plastic jacket need periodic replacement?

The internal copper wire is rated for continuous use; no scheduled replacement is required unless physical damage occurs.

What is the first limitation you hit when running a CCTV camera continuously through this 16cm extension?

The 3.5x1.35mm female connector’s current rating becomes the limiting factor before the short copper run adds measurable resistance.
