DC Power Connector 20 Pairs CCTV Power connectors 12V Male+Female 2.1x5.5MM DC Power Jack Plug Adapter Connector for CCTV Camera and LED Strip Light

I liked it, it made it easier for me to install surveillance cameras

These connectors are paired up. Good to have both sides.

I've only had a couple bad so far. No complaints.

These are great for DIY projects, testing, temporary installations, etc. When I make items with my 3D printer that require 12v power, I make a perfectly sized opening in the item for a connector, so you have a nice clean and stable port embedded in the item. The trick with these is to get the wiring stripped at the right length that it fits into the connector enough that the insulation of the wiring will be clamped in addition to the bare wire. Otherwise, the bare wire is the only thing connected and that makes it weak and susceptible to breaking. That's especially important if these will be at the end of wire instead of embedded or fixed onto an object. If you get a tiny bit of the insulation into the clamp as well, these are strong and durable. I would not use these outdoors!

Price for the number of connectors was fine. They work

These plugs have a couple of screws for attaching to wires, and that makes them really easy to install, remove, and move to other wires if necessary. I'm always working on "projects", and when I need a 2.5mm plug, now I have some. These should last me for a while.

Out of the 20 about 5 were DOA either due to poor voltage continuity or bad screw terminals. Then another 2-3 went bad over time (voltage begins to drop). They’re fairly sturdy in terms of build so I’m not sure what inner components/wiring they’re using to cause the continuity issues.

Great Product
