CHANZON (10 x Male DC Power Connector 5.5mm x 2.1mm 12V 24V Power Jack Socket for Led Strip CCTV Security Camera Cable Wire Ends 10Pcs Plug Adapter

Worked great as advertised, I used mine to hardwire a Reolink camera from an outside junction box, I wished it was a little smaller around but I still was able to fit everything in the junction box and mount the camera to it. I would recommend you use electrician tape around the connections for more peace of mind. Fits well, cables quality seems good. 10 in a box is pretty good value.

Use these to power my Arduino boards for my train layout. Easy to use and well built.

Work as intended but body is wide for a tight space. You need to torque screws pretty tight and then tape to keep wire from pulling out.

I was converting from some old surveillance cameras to some newer ones and the newer ones require a round connector instead of the older plug in connector. They work well for this and I'm sure if you had other projects to convert the right voltage charger to this size plug. The only minor item might be the bulk of the adapter, but it is so minor as not to remove a star.

Great for putting up security cameras that need the 12V power supply without having to run a cord. Most people want a security camera at their front door and there is a power supply already available (porch light). These can be used to replace the light and make a permanent installation of the security camera that looks more professional and doesn't need to have a cord running from the camera to an outlet. I highly recommend these. They work great with the Lustaled 24W LED 12V Power Supply.

Easy. to use. Especially for reverse polarity power jacks on guitar stomp boxes!

Worked great, if you are wondering about the Barrel length that plugs into your item it is 12mm/ 1/2" Long (the silver part) You will need a small Phillips to tie it up. Small like Computer builder small. Nature of the Beast, since it is a small part.

These standard 5.5 x 2.1mm connectors mate with other brands of that size easily, yet they are noticeably larger overall and appear more 'heavy-duty' than any others i've seen before. The female connector for example is over 4mm longer and almost 2mm wider than the less expensive ones i use most of the time. The male connector is similarly larger than it's lower-priced brother. You don't often need one of these to carry 5A, but these should do it easily intermittently, and while i haven't tried it yet, maybe even continuously. They're well-built, high quality, and seem intended for real heavy duty use. I'll update when i have further real data to add.
