Comments
I'm confused about the PD charging -- this device has one USB-C port that supports 100W PD charging. Is that an output or an input? I would assume an input and that input would then charge the MacBook? It really doesn't say in any of the description but since there is no dedicated power input to this device, I can't imagine 100W output.
