Adapters in use that get too hot to where you can cook an egg on it is concerning. Because electricity runs through the JCD383, it is normal for it to become warm. In the case where it is too hot to where it is smoking, or harming you - please don't hesitate to contact support and obtain an exchange. We're sorry about your poor experience with us and hope to turn this around.
Thank you for the review,

Hello,
I regret to hear that you were not pleased with this multi adapter. This adapter will seem warmer that other electronic devices that you may be used to due to its aluminum casing. The aluminum will transfer more heat away from the internal components. A plastic case will act as a thermal insulator keeping the heat generated by the internal components inside of the device.
In the event that the device is defective and overheating we back our products with a two year limited warranty. We appreciate your feedback.
Thank you,

The USB-C Multi Adapter (9 Functions in 1) requires a computer to support "DisplayPort Alt Mode" for video out and "Power Delivery" for pass-through charge over USB-C. Without these features, this device will not function correctly. Please refer to the manufacturer of your hardware for more information on your device. ** Feel free to contact j5create Technical Support if you require further assistance.

Hi!

I'm so sorry to hear about the troubles that you've been having with your device.

This device will get warm to moderately hot but this is within normal limits. We have done stress testing on it and have found that the average temperature for this adapter is ~106 °F / 41 °C, while the adapter is under a full load or is being used continuously for >~ 1hr.

Remember that ambient temperatures can also affect the adapter's temperature as well as what the computer will operate at. Both Apple and PC manufacturers recommend that you use your computer where the ambient temperatures are between 50° and 95° F (10° and 35° C).

Some tips for managing the temperature: Make sure that you're using the latest software updates and that the firmware is up to date. Your computer should only be used where the ambient temperature is between 50° and 95° F (10° and 35° C). Don't leave your computer in your car because temperatures can exceed this, especially in the summer! m

In testing our device, we have found that most computers will run the adapter at a temperature of ~100 °F / 37.78 °C to ~140 °F / 60.00 °C, while the computer is under full-load or being used continuously for periods >~ 1hr.


If you are finding that your device is running hotter than the average temperature of 135 °F/57 °C, for periods > 30 minutes, your product may be faulty and may be needing to be replaced. We haven't found that it runs at anything higher than 112°F/44 °C, for periods <10 minutes under normal circumstances.

If it is running higher than that for you, we do recommend reaching out to us at either the back of the product box or at the contact page on our website and we'll be more than happy to assist you further.

Hello,
This adapter will seem hotter than you would expect due to its aluminum construction. The aluminum will draw heat from the internal electronic components where plastic would act as an insulator keeping the heat internal to the device. If you have any additional questions I would recommend contacting j5create customer support.
Thank you,
