But the MBP charger is a lot heftier and 9 out of 10 times I don't need a charger. That's why I started looking for an answer to this. I just want to carry the smaller charger.
You can use either charger with either Mac. You just won't be able to charge the Pro from the Air charger while using it.
Carry what you like, you now know what the result will be.
