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

Ive been using similar connectors for a decade, but recently they all changed to a new design that doesnt work with thin wires and doesnt hold large wires securely. THESE are NOT the same junk that is seemingly identical in every similar product listing... the openings arent blocked by the clamping strip, the barrel metal is thick, and the set screws seem not to strip out. If any of that changes as I use more of them, Ill update this review.

really easy to use and figure out

Was exactly as described. Great adapter for the price.

I used these (and their female counterparts) for connections between my 12 volt transformers and my balancing LiPo chargers that I use for 3S 11.7 Volt batteries. I was charging 2 batteries at the same time, putting about a 4.2 Amp continuous draw on the connectors for about 1-1/2 hours. I checked the connectors for heat-up, and found none. Some have commented that it is hard to get wires in. I loosened the screws a bit and stuck a scratch awl into the holes to push the metal shrouding open and the wires slipped right in. I like the fact that by design, the screws do not screw into the wires. They screw down onto the metal connector material, which in turn, presses down on the wire. That way, there is no damage to the wire from the rotating action of the screw. It would also be advisable to tin the wire ends to make them easier to insert, but I did not do that with the 14 Ga. wire that I used. It was a tight fit. The product description says 16-26 AWG, but I did get it to work with 14 AWG. These connectors are also considerably large and heavy. So you may want to use a different option if you need to use them in a tight space.

I used these to connect a power cord to a Lithophane I made.

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 ive 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 its lower-priced brother. You dont often need one of these to carry 5A, but these should do it easily intermittently, and while i havent tried it yet, maybe even continuously. Theyre well-built, high quality, and seem intended for real heavy duty use. Ill update when i have further real data to add.

I used the male plugs for the delivery of the DC power to my 16 camera security system. I replaced the multiple smaller transformers with the security camera system with a single power supply and needed to have the male plugs on my power cables. This was a very easy install requiring no soldering of wires or connections. I only wished I could have purchased just the male connectors as now I have 20 female connectors that I cannot use. Still a great purchase as I was able to completely rewire the power with a minimal amount of effort.

Works great!

These are very easy to work. They have a solid connection and no slop when in use. Ive built a bunch of extensions for my multimeter and for my power supplies. Makes change overs so much quicker & easier.

Easy to use.
