DC plug expansion card for compatibility with more power adapters

I think this would be pretty cool, @Kieran_Levin mentioned the laptop has a buck-boost charger built in, maybe he can chime in if we can go around the pd protocol and just put voltage on the + and - pins.

@Kieran_Levin

We chose a buck-boost charger which can charge on any input voltage from 5V-20V.

If the converter is built-in, that would make my job a lot easier. I thought the expantion card ports are standard USB-C ports.
