    Short C chord, does not allow easy connection. This would have had a long chord it would be great.

    I bought this to extend my notebook computer display over two TV sets, I found that using this, the built in HDMI port I was able to display over two TVs plus the notebook screen.

    This was perfect for streaming from my phone to my TV but eventually that phone died. My replacement phone does not allow this technology so I had to give it away.

    It works good for displaying on monitor but the charging feature is garbage. It doesn't charge, it just slows the power loss

      Hello Kerry,
      The power adapter that you are using with the JCA379 may not be providing sufficient power to charge your device through the adapter. If you would like further assistance with the JCA379 our customer support team would be happy to help.
      Thank you,

    Most of the USB c adapters are ranging at 50 dollars or more. This one is very reasonably priced at less than 40. Cheap plastic but does the job and allows HDMI output to USB c computers

    Not sure if the USB C was broken or just not what i needed to run my extra screen but it didn't work. I have another of these and thought it was broke, but i guess it is my monitor. The HDMI and USB drives work well.

      The USB-C power-in port on the Adapter is to allow pass-through charge when a power-brick up to 100W is connected, not intended to add another display. For pass-through charge to function, your device must support USB Power Delivery 2.0 or 3.0. Please refer to the manufacturer of your hardware for more information on your device. Thank you. j5create

    The perfect adapter for laptops without HDMI. It also saves a USB port, allowing the wireless keyboard/mouse to stay plugged in when you take the laptop out.

    You can’t beat the price compared to genuine Apple comparable product. Long term though, can’t be sure of longevity. Apple cords to have lifetime guarantee...maybe that why they cost more than these off brands.

      Hi,
      The JCA379 is a good display adapter because it offers the extra USB-A port in addition to the HDMI port. Thank you for sharing your review online.
