Thank you, Justin.

I can understand a bit of variance on the input current with Switching power supplies. I am pleased with having a approximate current number. It helps my current thinking and the rating I need for a USB3 Hub.

It also makes certain that using a PC USB3 port will most likely NOT have enough current, so the second connector on the cable has to be plugged in as well to make up the difference, otherwise one should expect flaky performance….
