What's the minimal power adapter that will charge the laptop?

How small are you looking for? Anker makes some really compact PD chargers.
In fact, the numbers you mention sounds like this one https://www.amazon.com/Anker-Charger-Compact-Foldable-Included/dp/B0BDKCBJ95
That should work. And it says it can do 45W if you’re only using a single port.

@TvE I own this unit and can vouch for it working. Your battery may drain if you are charging two devices while also putting the laptop under heavy load.
