      Correct. The other commenter is giving bad advice.

      Both power delivery and bandwidth are backwards compatible, but they are independent specifications on USB-C cables. You can even get PD capable USB-C cables that don’t transmit data at all.

      Also, that’s not true for Thunderbolt cables. Each of the 5 versions have specific data and power delivery minimum and maximum specifications.

        I don’t think this is right. The PD standard requires the negotiation of which side is the source and which is the sink, and the voltage/amperage, over those data links. So it has to at least support the bare minimum data transmission in order for PD to work.
