12V DC Power Connector 5.5mm x 2.1mm 24V Power Jack Plug Barrel Adapter for CCTV Security Camera Led Strip Light (2 x Male + 2 x Female)

These are exactly as described, and work well.

These plugs and Jack's are especially useful for powering devices and power adaptors.

I bought these to extend a low voltage line that had the female end already on from the factory. It was a perfect fit and all I had to do was strip the wires and screw down the terminals, observing the marked polarity. I did wrap them with electrical tape to prevent incidental shorts.

I got these for a project I’ve been working on tirelessly for months in hopes to finish it once and for all. Sadly I didn’t need it for the project but I’m keeping it anyway for the future in case I need it. For the value of the money, I’d say they’re decent in price but I admit packaging wise I wish they packed it as all together because when I got it, they were lose in the shipping package. While I think the screw in portion is a great idea and saves one from needing to solder, it does have its drawbacks because if you use a wire, the wire will come lose. Quality wise I’d say it’s pretty decent and does the job and will fit with the ends of batteries. Overall I’d say it’s easy to use if you have a battery pack with no end port, but just make sure to use a wire with an ending to it that can keep in place.

Works perfectly for my application, quality product at a good price

Works

like, power supply for my sony tc730 taperecorder cooling fan.

After years of use, the LED controller of my 2017 Aerogarden burned out. I cut off the controller, wired the LED panel directly to this connector, and paired it with a 19V charger—problem solved! Works perfectly!
