    Can't get 2 HDMI outputs from my laptop

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

    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.

      The HDMI on the device supports a feature called DisplayPort Alt Mode over USB-C. Please refer to the manufacturer of your hardware for more information on your device. Thank you. j5create

    Dependability worth the price

    Bought this to replace a similar device by Insignia that did not work dependably. No issues with this one. Worth the price difference so hard drives and thumb drives stay mounted.

    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,

    Purchased two of these adapters and they both failed within 3 months. The first one failed in the first week and failed to deliver power through USB C or image through the HDMI and USB C.

    This worked great to connect my laptop to my desktop monitor! ...but I've only had it for a month and now it won't charge my laptop while I use it, which makes it kinda useless. Is there a fix for this?

      Gamebreaker7000, Customer input is always valued and we appreciate it. When it comes to the JCA379 not charging, this could be due to you requiring a higher wattage power adapter. If you wish to obtain assistance on getting properly setup, please reach out to the support team and a specialist will be glad to help any way we can.

      The USB-C to HDMI & USB 3.0 with Power Delivery supports up to 3840 x 2160 @ 30 Hz resolution via HDMI. We recommend HDMI to HDMI cables, no conversions. DisplayPort v1.2 required on graphics card or video source to support 4K @ 30 Hz resolution. ** Feel free to contact j5create Technical Support if you require further assistance.

      Bluebird, the adapter is considered a Plug and Play device, no drivers required but the computer must have a feature called "DisplayPort Alt. Mode" and "Power Delivery" to support PnP devices. If you have any questions regarding the device, our contact info. will be on j5create.com and we'll be glad to assist you. Respectfully, j5create. j5create

    This product doesn't connect the HDMI from my laptop to my monitor. It worked once, for about 2 min, and hasn't worked again. The monitor says the HDMI can't be read, yet works fine without this product. Waste of my time, now I have to spend even more time returning it and purchasing something else
