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?

That's the question... if I knew that, I wouldn't ask...
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

My Roamio's supply:

My Tivo Roamio just crapped out last night. Getting the Green then Red/Blue light flashing sequence which I believe is a bad power adapter.

So I bought this. https://www.amazon.com/dp/B01N7RS0NG?psc=1&ref=ppx_yo2_dt_b_product_details
Should that work?

And is my light sequence diagnosis correct? Should find out in a few hours if the new power adapter will work.
I bought this one, recommended by someone here. It is 3 amp and I like that it has a wall plug rather than a wall wart. I leaves more room on the power strip for more equipment.

Thanks. The one I ordered is working. Liked it was universal so I can use it for other things if needed.
If this one goes I will get a 3amp one. The old 2amp one lasted for years so hope to get awhile out of this one.
