    Manufacturers are allowed to add supplementary charging standards on top of USB-C PD

    Controversial opinion: I wish this wasn’t the case. So many different proprietary protocols, most of the time you’ll still need a specific adapter, and in some cases even a proprietary cable to utilize the full speed, and nowadays most devices come without the adapter.
    And there’s even PPS in the PD spec allowing to request for a specific voltage rather than something in an existing list.

    But I do also have some personal grievances here:

    1. Mi TurboCharge - This may be something based on PD, but still being something separate. I don’t know, but I do know it requires more pins than USB-A has. 5 pins. Somewhere I read this is connected to a CC pin in the USB-C connector. But no, they did not use USB-C, they used USB-A, with an extra pin. Only shortly before the phone died I finally figured out why it wasn’t charging as fast as expected - I wasn’t using their proprietary cable.

    2. My current phone’s interference (?) with Qualcomm QC 2.0 - Somehow when using a cable with non-perfect connection on QC-compatible adapters, when I move the USB-A connector, it starts triggering 12V mode until it finally shows overvoltage error and slows down to 7W. QC 2.0 is how my USB tester identifies it. This is a MediaTek-based device, so I don’t think it would support QC. The original adapter uses PD and some 11V 6A thing with unknown protocol. Perhaps that is where the problem originates, I don’t know what data it sends down. But testing with OTG adapter on the original brick it seems the protocol needs the extra pins of USB-C to work properly.

    I’ve had 3 phones that supported some fast charging, so far 2 of them made it into a confusing mess. Had they all used just PD it would have been a better experience.

      I agree, but at least requiring USB PD, as it’s written, will at least give you 240 watt USB-C charging if they offer higher than 240 watt charging through a proprietary standard

        If you have a cable that supports it, which is not usually obvious. And if you have a charger that supports it, which tends to be easier, but again, not always obvious. And don’t even start on transfer speeds or whether or not it’ll support lower usb standards like keyboards and mice. (I have a fairly high end cable that supports the highest speed data transfers but a keyboard will not work on it)

        Micro was the worst connector I’ve used, and I’m happy for its demise, but at least I knew what I was getting when I plugged it in.

          Transfer speed isn’t part of this regulation, but yeah, making it clearer on the box the max power output on chargers and cables would be a good continuation of the requirements

          Mostly. There was some nonsense about fast charging if the data lines were shorted together that made things weird from time to time.

      From Annex Ia of directive:

      3.2. ensure that any additional charging protocol allows for the full functionality of the USB Power Delivery referred to in point 3.1, irrespective of the charging device used.
