Antrader 5.5x2.1mm 2 Pin DC Power Female Panel Mount Jack Socket Connector | 3A Current Rating,24 Pcs Pack,Stable Conductive Contact for Power Supply

Worked great. It has the little size tabs on the back so make sure you get the right connectors or soldier the wires on. Good tight fit on the other side of the plug. Decent hole size tolerance since it has good flanges and hardware. Easy install. Good for thin to about 3/16" thickness of mounting surface. Worked perfect for my project. Great value.

We only needed one of these to fix a small Raspberry Pi based arcade game that we use in campus visit days. These come in 24 packs so we have 23 extra, but the one we used absolutely did the trick and we've got spares.

They are jacks. A bit of a tight fit.

They work well and there's a nice quantity of them, especially for the price.

Handy for electronic projects...

I've been using these for years, been through a lot of them, and have never had an issue with a single one. Fantastic for guitar pedal builds and whatever else you can dream up.

Easy to solder to, connects very well and is a reliable socket, will buy again if I ever use them all up.

These female socket connectors are well made and consistent across the pack, which is exactly what you want when working on small electronics projects. The fit on standard pin headers is snug without being overly tight, and the plastic housing feels solid enough for repeated use. They’re reliable for quick prototyping or building small harnesses, and I didn’t run into any issues with loose connections. The only thing holding them back from a perfect rating is the depth. They work fine as is, but if the sockets were just a bit deeper, they would offer better support and strain relief on the pins. That extra depth would make them feel more secure, especially when stacking or routing wires in tighter spaces. Overall, they’re a good value and perfectly functional, just shy of ideal due to the shallow design.
