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 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.

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!

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.

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

They sent the wrong size.

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

Cable is as advertised. Works well. Taking one star off because the female end would be a little tighter.

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

As described and delivered right on time.
