🔌 5 Pairs JST-XH 2.54mm 1S 2 Pin Balance Plug Lead Socket Male and Female Connector with 10cm Silicone Wire Cables: Perfect for Woodland Just Plug Lights & 3D Printers Review

I thought I checked everything for polarity. I skipped one and then fried a $60 controller board with a $0.70 connector.

This is the only one I could find that has the correct color coding for adding a wired fan header to a 3D printer. Generally seems correct for any use with a fan.

I have reordered these connectors. While they're not cheap, the connection is very secure, and the handy red and black color coding makes it easy to connect polarized items like batteries, LEDs, and speakers. I love her.

While everyone is happy the only thing to complain about is how easy it is to pull the pins out of the socket with wires. This may be true for all JST connections, but at least these seem to be easier than I expected with these, but otherwise very happy

Awesome! Pleasantly sharp click when plugging in the cinch plug. Strong connection. I like that you can hold onto the mounting nut and rotate the body of the block, turning the key almost easily. This gives you plenty of torque to tighten the fastener. It is very easy to securely mount the device. Three screw terminals make it easy to prototype or just build permanently. Just a suggestion. I wish the screw heads had a deeper groove or maybe even better a Philips head.

This is a very high quality JST-XH 2.5mm connector. You won't find better quality. However, be sure to check the polarity as it is not standardized. Most products have red on the left, this one has red on the right. As said, this is a great product, just make sure the polarity is correct for your application - check the picture carefully. If you're reading something like 2.5mm or 2.54mm, the difference is so small it doesn't matter. But that's an XH connector, and that's 2.5mm. RE is 2.54mm.

A quick addition to my previous very positive review. I feel like I was a bit hasty with a positive review. The product arrived on time and appears to be well made. Just a small problem. When I first started using these connectors, I quickly realized that the red and black wires were reversed and did not reflect the correct polarity. This is disappointing. It is possible to use cables with JST connectors, but you must connect them in reverse order or you will short out the battery. Apparently…
