I understand that an electric supply can be a higher voltage (120v, or 240v, etc.) and within those voltages be a different Amperage (15A, 20A, 50A, etc.).
But none of this is “smart” or doing anything special besides supplying an amount of power or amperage that is available by the connection.
I also understand that a battery needs line voltage (AC current) to be changed to DC to work. So I get that there is a converter (rectifier?) to do this.
So where/what is the “smart” part?
Can a charger really make my phone or car charge faster than the available electrical supply?
Can a charger really make my phone or car charge faster than a different charger in the same electrical supply?

For cars, AC current is converted to DC by the car, the charging plug and permanently installed charging equipment just provides access to high voltage/current AC.
For phones, there’s some communication between the host and device to communicate what charging profiles are supported.
