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

Just what I was looking for

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.

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

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.

These are well made connectors that I bought for replacing the power supply connectors used for my LED experiments. I deducted a star because not all the barrels have the same amount of hold (friction/tightness). They vary on some connectors.

Easy to use.

Works great!

really easy to use and figure out

Very easy to use
