    Hi,

    I will soon be getting a new MacBook pro for work (the one with two thunderbolt-3/usb-c connectors), along with two USB-C Digital AV multiport adapters to use like a docking station - so I can connect two HDMI monitors to the MacBook while at my desk while charging at the same time and also be able to plug in a USB-A to RS232 Serial adapter and lightning cable to iPhone or magic keyboard/mouse to charge that at the same time.

    What I am wondering is whether the USB-C port on the adapter itself can be used as a USB-C data port and not just charging. Because on one adapter I will be charging the MacBook and on the other adapter it will be empty and it would be handy if I could plug in a USB-C gigabit ethernet adapter there from time to time instead of using a USB-A one.

    It's really unclear from the apple website how well this adapter even works. It's not USB-3 right?

    Kind Regards,

    It's a passthrough port for power, it doesn't carry data (at least mine doesn't). Also, beware this issue: using this adapter my MBP thinks my monitor (Dell) is a TV, and consequently outputs YCbCr colour to it instead of RGB. This wrecks the colour balance (makes anything containing red massively oversaturated, especially). I've got a USB-C to Displayport cable on order to hopefully get around the issue until someone actually ships a Thunderbolt 3 dock...

    The full specs are as follows:
    • A power-only USB-C port that can pass through up to 60W
    • A HDMI 1.4b port that can support up to 1920×1200 at 60Hz, or 3840×2160 at 30Hz, or 4096×2160 at 24Hz
    • A USB-A port which supports USB 3.1 Gen 1 for up to 5Gbps of transfer speed and up to 5W of power*
    Hope that helps.

    *Which is less than the power provided straight from a USB port on recent Macs, making it incompatible with some high power requirement external hard drives

    thanks! so the USB-A port does support USB 3 speeds, thank *** for that. It's amazing what rubbish people post on the internet. Where did you find the spec?
