Hey everyone

I want to connect a UPS to my BT Smart Hub 2 and I was hoping to input the BT standard plug into the UPS then a the correct cable and connector into the back of the Smart hub.

Issue is I need 5.5mm x 3.0mm Female to 5.5mm x 2.1mm Male DC adaptor to do it.....All the kits I looking at are the other way around and I am unable to locate a 3.0mm Female at all.

Anyone know of one?

Thanks everyone

Farnell do the plugs, but I never found a socket when I looked a few years back. Might be easier to make up your own lead.

If memory serves, the old Home Hub 5 type A used the same plug, so you could cannibalise an old one off there. (The type B was different)
