    I know the power supply for the Romeo is 12V and 2-3 A, positive tip (+).....

    The only question is: what is the size of the PIN ADAPTER?

    ?mm x ?mm please!

    Usually there are 2 numbers associated with the pin plug..

    inside (ID) and outside (OD) diameter is what I’m looking for..

    for example: 2.1mm ID 5.0mm OD

    I'll be glad to look them up for you. Where would I find those numbers?

    Actually, 2.1mm ID 5.0mm OD is correct. Just checked to confirm.

    I did a search trying to find the ID and OD for my Roamio (Series 5 - TCD846500) power adapter (photo below) and found this thread.
    However, in another thread here (linked below), some Roamio owners are using the Chanzon power adapter (link below) which has a 5.5mm OD, not 5.0mm...
    So is the 'OD' 5.0 or 5.5mm for TiVo Roamio Series5 - TCD846500?

    I am also trying to confirm the ID since the Chanzon works for both ID 2.1mm and ID 2.5mm due to 'self adapting' DC plug that works with both.
    So is the 'ID' 2.1mm or 2.5mm?


    Chanzon adapter which some people confirmed they are using with the Roamio:

    Another adapter which someone mentioned also works is in the same thread and is 5.5 x 2.1
