It’s done by increasing the voltage to up to 48 V when the device requests it and both the charger and the cable support it. At 48 V that’s “only” 5 A, which isn’t nothing but nothing to worry about, and your phone will never request it and your normal phone charger won’t be able to output this much power anyway.
Is there any indication how much power a USB cable allows if I see them on a shelf? They all say “USB c” and “fast charging”, but hardly get into specifics. And a higher price doesn’t necessarily mean the cable has higher or better specs.

The cable I recently bought at Microcenter mentioned support for 24 and 48v charging.
