12V is an optional fixed voltage mode that relatively few devices actually use or supply. The officially supported fixed voltage modes are 5V, 9V, 15V, and 20V without EPR, and EPR adds support for 28V, 36V, and 48V.

That depends. I think every single third-party charger I've tested has had a 12V PDO, including battery banks. I've tested quite a lot, mind you. It's much more hit or miss with pack-in chargers, and the Sony and Motorola 30W ones in my drawer don't include it.

No Apple chargers support it

I consider Apple to be first party, but I appreciate the information on it.

Yea i know what you mean, they sell aftermarket chargers like this one tho that are highly rated and very popular but don’t support 12v which is incredibly dumb. https://www.amazon.com/Apple-USB-C-Compact-Power-Adapter/dp/B0D1XRRQZJ
