A charger that supplies 15 volts might not supply the 9 volts some devices need, or 20 volts that yet other devices need. USB-PD requires only 5 volts from chargers. Complicating this further is that not all chargers follow the USB-PD spec. What appears to be popular is Quick Charge, or just QC. The newer QC 4.0 is compatible with USB-PD but QC 3.0 and earlier is not. I believe it is USB-PD 2.0 that supports 12 volt charging but this is not part of USB-PD 3.0. USB-PD 3.1 adds voltages up to 48 volts. | |
