A:Answer Yes, it does have power pass through. My MacBook Air M1's power supply plugs into the hub, and the hub's dual USB-C plugs transfer power when plugged into the computer. One thing to note: Apple has physically tightened their USB-C jacks to make it harder for device cables to disconnect accidentally. The first time I used the hub, it did not seem to be working. Eventually, I noticed a small gap between the twin USB-C plug and the side of the Air. I gave the plug a more forceful push... there was a click... and everything plugged into the hub came on.
