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

They work, no issues

These and a 9 volt battery

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.

add to all my cables

These are really handy. I am a DIYer/tweaker and I got these to make my own custom DC cables. I use a fairly thick star quad cable and finding solder barrel jack are almost impossible that will handle this thick gauge of wire. These screw terminals handle that gauge with ease and tighten down tight enough that I am not worried about the wire falling out. With these I can make a DC cable in under 15 minutes. Finish with a bit of shrink tubing and the cable looks really good. Excellent product!!

Didnt know this product existed but an excellent product to very easily replace connector.

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

Quality is good

Works great just as described.

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.
