Question

Charger

What happens when you plug your MacBook into Apple's new 20W USB-C charger? She does not know how to give out more than 9V and they will not agree?

And if they agree that it would work somehow if the MacBook needs ~ 65 W and it gives, say, 20 W, or maybe less with an increase in the requested voltage.

Answer 1

The MacBook will charge until it consumes more than the PSU can supply.
Then the macbook will cover the missing power with the help of the battery. In general, UPD
will be enough to surf the Internet .
