> An adjustable voltage supply mode allows the device being powered an ability to request intermediate voltages between 15V and up to the maximum available fixed voltage of the charger.

So devices with this should be able to power anything in the range of 15-48V?

This was already a thing with USB PD 3.0 called Programmable Power Supply (USB PD PPS) which can request between 3.3 and 21V in 20mV steps

I have a USB c docking device connected to a USB c charging block. The block has three ports. And can deliver 45w,30w,20w,15w,and 10w.

When plugging in a second device to the block, the docking device goes off and then turns on. Meaning the block has to turn off and boot on every time a device is removed or inserted.

And basically nothing supported that.

Anything up to the maximum of the particular cable used (eg the cable could be maxed out at 24V)

It would only power devices which do not draw more current than (240 W/Voltage) Amps
