Lsgoodcare 5.5MM x 2.1MM 10Pcs Male & 10Pcs Female DC Power Plug Solder Power Jack Adapter Connector + 10Pcs Dustproof Plug for Enhanced Compatibility in Audio, Video, Phone, and CCTV Applications Review

These DC Plugs Will Work If If you're in a tight situation, just don't try to push anything over 5 amps through them or they'll melt. They are made of very cheap plastic and don't hold up very well. Only buy if you have no other choice. I tried to use these connectors to power the PTC heater for my resin 3D printers and these connectors didn't last, I had to replace them with increasingly powerful barrel DC connectors. BUYER WARNING, PURCHASE AT YOUR OWN RISK!

I bought this item to fit in a guitar effects pedal. Installing or soldering the wires isn't difficult, but the socket connectors included in the kit don't seem to fit snugly enough on the pin to ensure permanent contact. I can't plug it in at all and can only get sporadic flickering of the LEDs when moving the plug around. If I'm lucky enough to have the LEDs stay on, the moment I touch one of the footswitches it loses contact and the light goes out.

The sockets are NOT sized, they are 2.1mm x 5.5mm. The center pin in the socket should be the larger 2.5mm, but it is the smaller 2.1mm. They do not provide good electrical contact, if any. The plugs were the right size as advertised. SEVERAL ORDERS HAD THE SAME PROBLEM - I thought maybe it was an accident that they were different sizes and ordered it again but it was the same wrong mix. Who knows how many of these got mixed up in the packaging.
