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?

No, it can’t create more power than what is being supplied. So if the charger has a supply that is 12v at 1.1 amps (13.2W) it can’t somehow supply 12v at 2 amps (24W). At least not constantly, it can supply the 12v @ 2 amps in short bursts, but its output over time will still be 13.2W or less.
