      Emilio, Depending on the power requirement of the phone, charging through the JCA379 may or may not work. This would be due to a higher wattage power requirement needed. If you wish to obtain more information on this, our support team can be reached via email, chat or phone. Thank you reviewing the JCA379 and we hope we may still help if needed.

      Hello Chuc666, I'm sorry to hear about the JCA379 not working for you. Because the JCA379 is a plug and play model, it requires that your computer, phone, or tablet support charging and DP alt-mode via USB-C; in the case where the USB-C on your device does not support such feature, the JCA379 will not fully work for you. If you would like to learn about different models that will output video for you, please feel free to reach out to support and an agent will gladly help find you something that will work. We apologize for the inconvenience and hope to hear from you.
      Respectfully,

    USB A doesn't work with power pass-through. I'm trying to use this as an OTG cable with power pass-through but if power is plugged in it only charges no USB A. Completely worthless, plan to return.

    No, I would not recommend this to a friend

      The USB-C port is the pass-through charge, not the USB-A port. However, computers must support USB Power Delivery 2.0 or 3.0 for the USB-C to HDMI & USB 3.0 with Power Delivery to be compatible. Please refer to the manufacturer of your hardware for more information on your device. Thank you. j5create

      If you are using high-powered USB devices, attach the USB-C power adapter to the power delivery port to ensure maximum performance. When using your USB-C power adapter, the multi-adapter powers both the adapter (with attached peripherals) and your laptop. j5create

      The USB-C to HDMI & USB 3.0 with Power Delivery requires an All in One to support DisplayPort Alt Mode and Power Delivery features through it's USB Type-C port. Without those features, this device will not be compatible to your unit. Please refer to the manufacturer of your hardware for more information on your device. Thank you. j5create

    It works well for what it's designed for. I just thought I could use both the HDMI that this provides and the HDMI on my laptop at the same time. I cannot get that to work on my ThinkPad.

    Doesn't support 4k over HDMI

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The Bad: Kind of a clunky size and design. The HDMI port does not support 4k resolution, so DO NOT BUY if you plan to use with a 4k display. Two USB thumb drives have been corrupted when plugged into this thing, I can't say for certain it was the fault of this adapter or not, but sure seems like it. This thing should have an ethernet port! The Good: USB is working for my keyboard and MacBook 85w power supply is plugged into the extra USB-C port providing power through this adapter so that I'm able to eliminate one plug. I would not buy this again...

    No, I would not recommend this to a friend

      The HDMI port supports up to 3840 x 2160 @ 30 Hz resolution. Computer's GPU must support 4k capabilities. Optional power adapter can be connected for charging a laptop or other power consumption device. j5create

      Hello Angel,
      We are happy that you are enjoying the device. There may be a solution to the dilemma with the battery drain on your phone. A higher wattage charger plugged into the USB C port on the adapter may resolve this issue. For assistance and further details about this you can contact our customer support team. Their contact information is on the product packaging and on our website under the Support tab. Customer support can help you by email, live chat, or over the phone.
      Thank you,
