12V DC Power Connector 5.5mm x 2.1mm, CENTROPOWER (10 x Male + 10 x Female) Power Jack Adapter for Led Strip CCTV Security Camera Cable Wire Ends Plug

these are very easy to use.

These work great and its very easy to extend low voltage wiring requiring barrel connectors this way. Be sure to really tighten down the two screws on your wires, and pay attention to the positive and negative terminals!

Nice having simple screws to tighten and use.

Used these connectors to put together a 12v power line for my camera, worked perfectly

These connectors work well with one exception. It may be of my own doing, but the screws at the wire terminals did not hold the wire well when tightened. I had to really torque down on the screw, and/or re-strip and reinsert the wire a few times before I had a good, tight connection. That could just be the wire I was using, or something else. Anyway, that was my experience.

The 10x male and female 5.5mm/2.1mm connectors are exactly what I needed. I used these for a 12V lighting project and the 18AWG wire I used fit into the terminals with no problem. Stranded 16AWG will fit as well. These appear to be well built and made of good quality materials.

Performs as advertised and is well made

Would buy again

Very easy to use

Very good value. Used to connect battery charger to lithium 18650 battery pack for my e-bike
