> USB-C only guarantee 60W charging. The original PD 1.0 spec went up to 100W (20V/5A). Newest PD spec (3.1) can do up to 240W. And I think apple's magsafe cable terminates in a male usb type C, so it still uses PD internally at least.

More than 3A on PD requires tagged cables, I'm not even sure I have any 5A capable cables here. I do have tagged cables as tagging is required for USB3 over USBC which is negotiated with the aid of PD. Magsafe does make it rather somewhat simpler for the end user and I never really liked that the main cable for a portable could be so easily damaged, I liked magsafe and the magnetic connector on the Surface laptops quite a bit.

  Precisely. Not all USB-C Cable are PD cable. Telling the story again. I was trying to help a lawyer out and trying to explain why the $5.00 USB-C cable he'd bought from Amazon wasn't delivering 4K video to his expensive monitor AND powering his laptop too. Me: OK: so its a USB-C cable, but its not a high data rate USB-C cable. Him: But, its a USB-C Cable. Me: but, no, not all USB-C cables are high speed cables. And some of them can't do high speed and power delivery Him: but... its a USB-C cable: it plugs into the port. Me: Um... just because it plugs in, doesn't mean its going to work. You can have USB-C cables that are actually slower than the old USB ports. Him: but.... shouldn't it just work? And so on. For... 15? more minutes? maybe 30? I finally got him to buy a "proper" belkin USB-C cable . Which was bought from a company that should be anonymous, but lets just say that a "refurbished" cable was shipped, which, surprise, surprise ,didn't work, for ANYTHING. This basically sums up everything that is wrong with Tech thinking vs User Thinking.

    It's tricky because the good part of that port is you can plug anything into it, thunderbolt, usb, etc. But the bad part of that port is that you can plug anything into it and its hard to tell why it might not be working as expected.
