“ This 5.5 x 2.1 mm DC JACK plug are substantially better than using pigtails, they had a power connector cinch interface to another end terminal, a screw nut to attach the wire for a CCTV camera truck rod connected with a faster and safer cable connector. “ ------ Engineer Wilson “If you are installing your own video surveillance camera system, this maybe an option you need to include. “ ------ Engineer George “ I used them to power an Arduino with a wall-wart power supply. I drilled a small hole through the project's case and pushed the round part of the female end through and glued it in place. Holds the plug well and I haven't had any problems at all with it.” ------ freshman John Specs: ☆ Weight: 14 g ☆ DC jack connector 5.5 x 2.1 mm ☆ Positive and Negative: clearly labeled ☆ Color: As shown black + green ☆ Total size: 3.8 x 1.4 x 1.3 cm / 1.5 x 0.6 x 0.5 (L * W * H) What’s in package? * 10pcs Female jack * 10pcs Male jack Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.

Mine work as expected.
This made short work of tying in a LED controllers into 12V boat wiring. Surprised at the price and quality seemed good enough. Will use the remainder for Arduino or somesuch.

Not very re-usable
It is a good product but the terminals are not very re-usable. Once you tighten the screws down, the leaf portion bends down, and jams the wire. Make sure you get the wire full inserted as far as it goes, before tightening.When using 22 AWG solid wire, I had one intermittent connection on one jack. I think if I used something larger than 22 AWG, or stranded wire, it would have been better.

Well made connectors
A very handy bunch of connectors to have on hand in the ham shack. Quite positive connections at both the coaxial ends and the terminal ends. A smooth and snug fit, which means no worries about incidental disconnects.

Best solution for students and DIY, easier, more durable
Less expensive than most solder connectors, much easier to use and more durable. The only time when we will use solder connectors will be when there is a space constraint. Every other time that will be these connectors. We already bought hundreds.

Awesome product
Makes connecting a low voltage power supply to almost anything a breeze, easy to change your mind. Love this connector, you will to.

Very good product
Did what I wanted it to do. No complaints.Will buy more as I need them. Very good electrical connection, nice and tight.
