I have looked at various USB power delivery (PD) adapters that supply a certain number of watts and are powered by 230V mains voltage. Always, they seem to have either a USB-C port or a full USB-C cable permanently connected to the adapter. I have never seen a USB power delivery adapter with USB-A port, so that one could use it with USB-A to USB-C cable.
Does a USB-A connector even have the pins required for negotiating power delivery (PD)? I know it can supply at least 5V voltage, but I'm not interested in that; I'm interested in power delivery standard with much higher voltages.
Wikipedia says a PD aware cable needs to be used. Can a USB-A to USB-C cable even be PD aware? If it can, is it possible in practice to find such PD aware cables in the marketplace?
