Male Female DC Power Plug Connector 2.5 x 5.5/2.1x5.5 (Screw Fastening Type) Needn't Welding DC Plug Adapter,10pcs/Set (Male+Female Plug Connector 2.1x5.5mm)

Does its job.

Connectors seem to be good quality. Bought to use with the 12v output ports on my power station. Fills the need adequately.

We ordered some of these plugs end of February or early March and they fit really well. The latest batches were different plugs and don't fit well at all. We've had to crimp the ends to get a ok connection. We've only ordered the same part number for all of these orders. We liked the old connectors much better - they had a much tighter solid connection. My attached photo shows the old (good) plug on the left and the new (dud) plugs on the right.UPDATE 4/5/2021 - No reply on this review from seller and no reply from a seller email I sent. Looking for another source.

Not sure what else to say - it's exactly what I expected, good quality and delivered as promised.

product was well packaged and arrived on schedule

I have a battery power source that the specs call for a 5.5 x 2.5 mm plug for output. The center barrel does not make contact with the center pin. I love the screw-on feature of the connector, but it does not work with my power supply. I've purchased other 5.5 x 2.5 mm plugs for my power supply and they worked, so I'm not sure what the difference is here. Seems to be good construction, though.

They seem well constructed and work well.

They don't work good for ubiquiti switches or routers. Too loose
