Engineering wise it's a spec ASKING for trouble. A device telling host what VOLTAGE to apply?
The standard solution is that apart from naked cell / battery chargers (Lead Acid Car battery, or Lithium pack with no internal charger) is that a connector from a host or a power supply ONLY supplies a fixed voltage.
The existing USB charge currents other than C are NOT decided by the host, they are only 5V (+/- 0.2V) and the slave gadget examines the D- or D+ pins to see if more than 100mA can drawn. If you only wire +V and 0V, you get 5V and the current supply is whatever the host can do and the slave may take only 100mA or 500mA max depending on era.
USB-C is stupid.

I only have one thing that has a USB-C port and that's only used for charging. I use the cable that came with it. I did have a look to see about getting a second cable, but I have no idea what's a safe cable.
Yes USB-C was a big Fing mistake.
