but it takes what ? a hundred times the power that the slow chargers do ?

Let’s plug them all in at the same time and see what happens.

“but it takes what ? a hundred times the power that the slow chargers do ?”

No by definition 11C is eleven times the 1 hour charge rate.

DC to DC losses are 5-8% so 11.08 times the one hour current.

For a typical smartphone with a 5 amp hour battery that would be 11.08 times that so 55.4 amps at 3.7 volts to 11C charge a typical smart phone. That’s 204 watts.

The current fastest USB-C charging standard is USB PD 3.1 Extended Power Range (EPR), which delivers up to 240W (48V/5amps)

So the current standard could do it now.
