    I have an Alesis electronic drumset. The power cable from the wall wart does not reach and I didn’t want to stretch an extension cord and have the wall wart in the floor. This works great and really neatens the area up. I used shrink wrap to secure the fit even better. I love it.

    Needed an extension for some led strip lights.

Application:
Ideal for LED light strip, rigit strip, LED signage, and CCTV camera, lighting, car, boat, monitors, printers, sensors, DVR, external hard drives, audio mixing and recording equipment, or anything that requires DC input and accept 2.1mm x 5.5mm plug.
This unit only accepts 2.1mm x 5.5mm barrel plug from power adapter and will not work with other sizes.

Note:
Not all electronic equipment utilize 2.1mm x 5.5mm size plug, especially small digital device. The surest way to determine if this cable is compatible with your power adapter is by measuring the inner diameter and outer diameter of the plug of the power adapter. Buying the cable with the wrong plug size is a common problem.
Make sure that the power adapter can supply enough power over the extension cable. From 20ft and up the resistance and the drop off in power may become noticeable.
