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

These worked for me.

They work, no issues

I installed security cameras at a remote building, powering them up with a solar-charged 12 volt battery bank. The inverter I was using was extremely loud and I found it annoying. Using these connectors, I was able to remove the need for the transformer and connected the cameras directly to the 12 volt power source. Easy to install and work just great!!

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.

Great product. Makes power lead termination much easier however insulating exposed wire/connectors a bit tricky.

I bought this to attach to a solar panel charging cable and connect to a small 100w portable charging station and it worked like a char!. Glad to have companies out there making products for the DIY family!

Works great just as described.

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.

They were not advertised correctly

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