Nice video. Changing the power supply removes upstream power delivery? Or do you mean your MacBook Pro doesn't get power delivery because it's an older MacBook Pro with Thunderbolt 2?

I wonder, can a Thunderbolt 3 eGPU box with power delivery provide Power Delivery to a USB-C only MacBook? The MacBook can't use a Thunderbolt eGPU but it might be able to get power from one (Thunderbolt uses the USB-C Power Delivery spec).
