Re: USB-C for power
I have a Thunderbolt dock for my laptop, uses the same connection as USB C.
It supplies power to my laptop, and also has 3 USB A ports, 2 USB C ports, 2 Display Ports, Ethernet, and a 3.5mm speaker/microphone port.
That means when I arrive at my desk, I only have to plug in one cable to do everything, unless I want to attach 3 monitors to it (I do), so I also have to plug in a USB C/HDMI adapter to the other side of the laptop.
