If the requirement for socket-and-cable PSUs is required for Pi PSUs, I suspect that the RPT will start marketing a cable--and quite possibly include one with the PSU--with the required characteristics to properly be used between said PSU and whatever the highest current requirement Pi is in current production.Labeling of USB power is pathetic for many power supplies and most cables. A big problem will be Pi 5 on 6 amp supplies or cables not supporting the 5 amp mode. If a future Pi power has a separate cable, the cable will have to be labelled as Pi 5 compatible or 5v 5amp compatible. If there is a new power block, I suggest the block and cable support some of the other common options.
I have a USB block with four sockets with total of 6 amps. There are Type C and Type A sockets. I think the idea was to use just two Type A sockets then progressively switch to Type C. There are multiple power options on each Type C. My compatible USB Type C cables handle some of the power modes but not all. The combinations list is longer than the T&C pages for proprietary software.![:o]( "Surprised")
The block lets me run a Pi 5 on one 3 amp socket and the Pi 15" screen on the other 3 amp socket. If the screen is in the Pi 5 using the Pi 5 5 amp power mode, the screen reaches only 60% brightness. That is my main reason for a future Pi 5 power block supporting 6 amps across two Type C sockets.
Having said that, I've seen ads from Monoprice for USB-C cables that the claim are rated for 240W. I guess I'll have to take a look at them to see what the internal wire gauge is...
