dear deity-of-choice, why in your pit-of-the-forsaken did you not specify color coding the plugs or some other way to avoid what will be the obvious and inevitable problems?

They probably used one of the cables as a rope to climb out of said pit, but because there is no obvious way to know the spec, they chose one with hair-thin wires and fell to their death, thereby never able to tell the world of the obvious change that was necessary.

240 watts is interesting. Can fully power the vast majority of laptops even.

5a max.

Agreed. Would be a dream for a simple one cable docking station for programmers and other engineering fields

problem i see with something like that a general consumer would buy some cheap ass cable from 7-eleven or some knock off chinesse brand try to utilize 240w and it either wouldn't work and get pissed off, or they would somehow manage to burn down the house and sue the laptop manufacturer.

well then, I hope I never see a proprietary ebike cable ever again

If thats true, multiple conductors capable of 5A each must be used to achieve 240W otherwise USB 4 v2.0 will have to support 48V which could be catastrophic with the same connector used on old standards.
Its possible the supplying circuit can detect whether 12V is enough for a connected device before boosting to 48V but I'm not happy trusting that.
5a max alone is a poor description.

it is 48v 😕
usb3 PD already allows this as is.

Allowing the consumers to make informed and logical purchases?!
Never!
Folks like you are the bane of companies who want to make a quick buck and milk their beloved customers...

In the light of a new day its not a bad issue, was about to go to bed rather fatigued when I posted that, my bad.
The solution is straight forward, require anything that can use 48V to signal its capability/need.
Old kit cannot do that so will only get 12V max.
As long as failsafes are well implemented it shouldn't cause any problems.

The point is where can i get more slot for USB4 on my motherboard?
As most AMD board still using USB3 as of now
