I dont know if that works, but a difficulty of USB-C has been the power profiles and who charges what and when.

It’s weird, and I would think the potential would have to be way different between the two laptops but according to the spec it can work.

You can charge MacBooks from each other.

* First laptop you plug one end of USB C cable in will the the charger;

* Second laptop will be the one getting charged.

You’d have to plug them in at exactly the same time though.
