That's just USB-A which only does one voltage at different current limits. USB-C has a whole negotiation back and forth about available (charger) and desired (device) voltages. You could possibly have a device pass just those messages back and forth I guess but that's definitely not the device you linked.

Sorry, I don't have any USB-C devices, and the OP at top of thread only said USB (not USB-C).
