The problem is that the "industry" gave us one port for everything while giving us a confusing mess of mixed capability cables that use that port.
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.
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.
Because people actually want one cable for everything.
USB-C only guarantee 60W charging. Instead of telling user to use USB-C PD 2.1 Cable with Thunderbolt 4 support and this logo with x. Apple now tells its user if you want it to work at maximum speed and charging please use Magsafe.
