Yes. That’s what I am doing.
What happened initially was that I plugged in a USB cable into the 2.4A port, and started doing the testing on the USB-C cable by Ugreen with the UM25C.
I got a resistance of 0,007 Ohms out of the cable, which was way too low obviously, even for a 0,50m cable with 18AWG power wires.
I redid the tests multiple times, and still got the same results.
I then changed the cable out for my longest cable, at just over 2,5m, and redid the test,_ just to accentuate the difference._
Now, I had done the test on the QC 3.0 port, the voltage then dropped at 1A, and dropped even further at 2A compared to idle.
Now, when I did the test on the 2.4A port, the voltage dropped at 1A, like normal. What happened at 2A was surprising though: the output voltage was going up, significantly!
That meant the IC on the 2.4A port noticed the resistance of the cable was dropping the voltage too low, and upped the voltage then to compensate for the power loss to the device.
TLDR: The higher the resistance of the USB cable/connection, and the higher current, the higher the voltage compensation a smart port will do.
