ANTOBLE Power Adapter Compatible with Yealink T54W Power Supply Yea-ps5v2000us Voip Telephone Adapters Home Phone Charger Replacement Part 5V 2A Power Charger for Yealink Phone Cord SIP Accessories

This plug has been a life saver

So glad I found this for the phone. The original wire frayed. I had called several places and nobody had a replacement. I asked each place where I should try. They all said Amazon. I put in the make of the phone which by the way is very old as it is my work phone. It came up and the phone looked a lot different than mine again I am sure due to the age of my phone. I tried anyway and it fits great and now I don't have to keep getting up and wiggling the wire.

I actually used this power supply on another 5VDC input device I have that needed a new power supply. I took a chance on the end being the same, and luckily it is. The inner size of the DC plug accommodates a 2.5mm pin and the outer barrel diameter of this plug is 5.5mm ( so it fits into a 6mm jack ). In the product description it shows in the diagram of the jack being a center positive plug. So, if you need a 5v, 2A power supply for another product with this jack size, this will be fine. Other than that, it's a power supply and does it's job. It does have a green power LED indicating it's receiving AC power; a nice touch.
