Need an electrical solution: TV, Apple TV, M2P batteries, etc.

I see what I did. 1000Ahr@12v is 12000Whr, not 1200Whr.
12200Whr@12v would indeed be 100Ahr.

And your still doing it, 12200 Wh (no “r”) from a 12 supply is 1017 Ah (no “r”)- not 100....

How did that second '2' get in there?
Thats a typo rather than mathematical error.

And the 2nd equation it should have been 120v. The point was showing the different Ah for different voltages for the same Wh.
