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

really easy to use and figure out

Very easy to use

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.

Easy to use.

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