USB standard is up to what, 40Gbps and 240W? That’s pushing the envelope already. We’ll see if this new standard can prove itself, anyways.

Running that much power next to a data line sounds like a terrible idea for signal integrity, especially if something shorts to said data lines. It just sounds sketchy or filled with so many asterisks that it’s functional impossible to reach their claimed throughput.

USB4v2 can do 80Gbps and 240W.

It can also do 120Gbps/40Gbps asymmetric.

See, IDK anything about data and power and cables but I dislike the vibe when I dock my laptop with that itty bitty USB-C connector that does power and 2x monitors and networking and peripherals.
I did buy the bonkers expensive proper cable from lenovo, and it does generally just work, but maybe once every few weeks I have to unplug & re-plug.
More power and more data through the same cable just seems daft.

It’s likely dc current which without the alternating magnetic fields will not degrade the signal as bad. But I whole heartedly agree with you on power delivery. What could possibly need/use that much power‽

The option to run one cable to the monitor, or reversely charge your laptop with one docking cable.
Maybe you could use this to daisy chain monitors and power them all.

USB-C docks can already do this. Obviously with less power and it’s not perfect by any means, but we don’t need another technology for this. And sure, it’s two cables, one from wall outlet to integrated dock/monitor and usb-c from dock to laptop, but no matter the technology you still need something to plug in to wall outlet.

Bigass showroom screens I suppose?

its super nice to plug a laptop into a screen and have the cable double as a charging cable for the laptop
YiddishMcSquidish@lemmy.today 1 week ago
Yeah, agreed. But 480 watts‽

um, gaming laptop maybe?
Honestly no idea, you have a good point.
