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 …

The cable works and arrived quickly

I liked the product. Worked perfect for the Under counter lights

Have a Polaris Slingshot and wanted to install a unique mod. Needed a longer wire to reach the power source. This cable extension did the trick. Plugged it in, and my device worked perfectly.

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.

As described and delivered right on time.

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.

They sent the wrong size.
