    Dear Reader,

    I've recently bought this 9-1 USB-C Hub and I've been using it with my Macbook 12".
    Attached to the hub are:
    - HDMI to 1080P monitor
    - USB C to USB C cable (from pepper-jobs) to 30W official apple charger
    - 3.5 mm audio jack to Stereo.

    My issue is that the audio drops every minute/minute and a half if all the cables are attached.
    In sound settings, the USB headset disapears and reapears within a couple of seconds.

    If I unplug the HDMI cable, audio plays without any issues.

    This sounds like a power issue to me, is the 30W charger not powerfull enough to power everything and should I buy a more powerfull charger or is there something else I'm missing?

    It looks like the 30W adapter is not providing enough power for both charging the MacBook 12" while powering the hub.
    You may do a simple test - to use the hub without connecting to the charger, or connecting to a charger with higher output (if you have one of those).
    If the problem is gone, then it's very likely a power issue.
    (Worst case scenario, you still have a 3.5mm jack on the MacBook)

    I've recently bought the TCH-6 and I've been using it with my Macbook (13-inch, 2018, OS Mojave 10.14.2) but I have been having some issues:

    a) My macbook freezes regularly when I plug the hub in. When this happens, it doesn't help to unplug the hub, I have to force restart my macbook to solve the freezing. This seems to only happen when I'm already logged in. When I lock the screen before plugging in & then unlock with touchID, it seems fine.

    b) In the middle of transferring files from my memory card to my laptop, my laptop reported that the memory card had suddenly been ejected. This without having touched the device and several times in a row.

    My reseller (pepperjobsDOTnl) proposes to switch me for a TCH-MBP 7 but I'm unsure if this is gonna solve the problem + I will no longer have an ethernet port which I'm not that keen about.

    Thanks for your answer!

    When using multiple features with the hub, such as Ethernet + card reader + etc...
    it's recommended that you connect the charger to the hub to provide the power needed by those features.
    The MacBook Pro USB-C port, also USB-C port of other devices, do provide some power but not to the extend that it could support all the features working simultaneously.

    Thanks for your answer! However, the problems did occur with only a memory card in it, nothing more than that..

    Hi Lauren,

    It doesn't really matter how many devices are you using, when you connect the hub to the device,
    those many features need power, even if they are at idle state.
    Of course, when you are using them, they need extra power.
    Please connect to the adapter and let me know if the problem persists.
    We're here to help.

    Hi Ken!

    Thanks for providing support to us.

    I'm using the TCH6 with my iPad Pro and am having 2 issues.

    • I'm unable to charge my iPad pro via the hub. The charging icon on the iPad cycles every second between charging and not charging. Of particular use, I want to charge my iPad while using the hub's HDMI port.
    • When using the HDMI port, audio is routed to the 3.5mm jack and not through HDMI. Any suggestions? Plugging something into the 3.5mm port and then unplugging it works, but not always an option when I'm not carrying a 3.5mm accessory.

    Hi Andrew,

    The iOS/iPad OS doesn't have the ability to allow you choosing which audio output like you can do in Android, Windows or macOS, that's the root issue and we are also trying to solve it by changing the hardware design. Unfortunately, since you have already owned the hub, that means no fix apart from your 3.5mm plugging/unplugging trick.

    For the charging issue, may I know which charger are you using with? The original iPad Pro charger is only 18W, deducting the power that the hub needs, there should be only a few watts left. Do you have a larger power charger to try?

    Hi Ken

    Thanks for the info. The charger I am using has a max 33w output. Photo attached.

    I can see this is a travel charger, do you have a proper USB-C charger to try?
    Even the original 18W charger would be fine.

    I will try when I arrive home in a few days.

    Hi, how is it?

    You’re right. It needs the 16W to charge. I tried my 12/10/5W and nothing else worked. I’ll start carrying that around with me now.
