    Adapter works perfectly on my Samsung chromebook. USB types A and C ports work without any issues, as does the HDMI port. Build quality is also a plus and doesn't feel cheap.

    Bought this to be able to use the Dex feature on a Samsung Note 20 and a Tab S6. It did exactly that. It charges the device, outputs Dex to the monitor and we connected a wireless keyboard/mouse dongle to the USB slot and we are good to go.

      Hello,
      We appreciate that you shared your feedback on the adapter. Tablets and smartphones are becoming more powerful and have many more applications; but are limited in their native interface. Adapters like this one are really useful to add peripherals you mobile devices. Have a great day.
      Thanks,

    Works well but it's pretty expensive and shouldn't even be necessary. Drives me nuts that laptops these days have just one usb-c input. I bought the laptop at Bestbuy too.

      Ability to stream from a phone to a TV screen while still charging makes the JCA379 a great choice - simply plug it in and done.

      Hello,
      The benefit of the JCA379 is that it will allow for pass through charging to the laptop or other smart device that you are using with it. We appreciate your feedback and hope that you have a good day.
