Hub DC input question

[Hawkmoon19]

This is my hub. I want to try a different power supply with it but someone warned me that some BT hubs have a non-standard DC input size meaning not all 12v DC power supplies will have a DC lead that fits - anyone got an idea if my hub has a standard size DC in socket?

Is anyone able to help? Looking for some kind soul with same hub as me to measure the DC plug on the end of the power supply. I need the diameter of the inner stainless steel part of the DC plug and then the diameter of the plastic larger outer bit of the DC plug.

Which model of Hub is it?  Looks like a HH3 but I am not faimiliar enough  with all the models to be sure. If yoou give teh model number it will be much easier to answer.

It’s a smart hub (not smart hub 2)

It's not that easy to measure as it is either 2.1mm or 2.4mm, for what it's worth my money is on the 2.4mm

HH4 and HH5 had different size 12v sockets - I bought an adapter having bought a HH5 on an auction site for nuppence.

Going by post 4 it's an HH6

Do you see why I’m confused here - there’s talk of 2.1mm, 2.4 mm and then I found another thread where someone said it’s 3mm inner diameter.

I think I saw that thread and later he changed his mind - though I cannot remember to what size.

OK found the thread https://community.bt.com/t5/BT-Devices/Smart-Hub-2-DC-plug/m-p/2161511

Seem to day it is 3mm and a Philmore 206
