Xenocam 12 Pack 2.1mm x 5.5mm Male CCTV Camera DC Power Adapter Connector

I had to build a fan power cable with 8 drops, and these things worked great.

This product is used to provide terminals for DC power connections. Its usually used in CCTV camera work. Im using them to provide power for active metering.

does what it is intended to do. Cheaply made but gets the job done.

Simply the easiest way to add a 12v barrel connector to the end of a wire.

Gd product

Quality is good

I do a lot of work with solar panels and 12 volt systems like LEDs and cameras in my work and these are quick and easy to use solderless connectors for most common 12V systems. I will purchase more of these when I run low for sure.

I wired my receiver trigget power outlet to my AC Infinity AIRCOM unit with this plug. Works fine.

The connectors looked like a great idea with the screw down wire terminals which would allow a bigger gauge wire to be used with the 2.1 x 5.5 mm plug. Unfortunately the quality of the clamp and the plug is not very good. I connected using 18 gauge copper zip cord and the screw terminals would not consistently grab the bare wire tightly enough to hold as well as a soldered joint. When tightened down as much as reasonable for the screw size the wire could still be pulled out of one or both terminals. Part of this is due to the design, the clamping surface is very small and smooth and the short design of the plug places the strain too close to the clamp. If a person plans to use these for a purpose where there is zero pull or movement and then covers wire and connector with a continuous piece of heat shrink tubing they may work OK. If you anticipate any pull or movement of the wire it would be best to solder the wire in as well or rather use a solder-type plug with built in strain relief device. Im going back to using the soldered type fitting.
