SIM&NAT 20AWG 10Ft 2.1mm x 5.5mm Male to Female DC Extension Wire Power Jack Adapter Barrel Plug Cable, Extension Wire for CCTV Security Camera, DVR, HDVD, LED Strip Light, Low Voltage Application …

I used these to connect my effects pedals to my power supply and to connect a second 18v power supply to its effect pedal My PA system has no hum now!

Excellent service and the quality of the cord is excellent. Very professional group

I purchased this to avoid having to make a custom length cable to power an ESP32 mounted behind a wall hanging. The extra length this extension provides allows me to run the cable down the corner of the wall to look a lot better than simply dangling because it was too short. I have not noticed any problems powering the ESP32 which runs WLED with about 8 feet of 60 LED/m addressable 5050 LEDs.

Worked great to extend a cable on a light snow machine.

This cable is black, with male barrel connector on one end and a female barrel connector on the other. Both are 2.1mm x 5.5mm, providing an extension cable for connectors of that size. The cable is well constructed and bends easily for manageability. The product was packaged nicely in a zippered thick plastic bag with a twist tie holding the wound cord together. Easy to install as an extension cable and works fine as a power extension for my drive way monitor receiver.

Worked perfect

It`s just what I needed for my lights, at a good price.

As advertised

Did the job it needed to do

They sent the wrong size.
