Power saving features of circuits should throttle the power if nothing is connected, if such feature does not exist in the hardware they should not be used in 2020. Sorry to say, but all USB-C adapter hubs that get warm with no usage is pure crap from hardware designer point of view. This is problem for all consumers in the end, as high quality products get harder to find. They just dont care, and they get away with it because of consumers that dont care. This product can damage USB memorysticks, memorycards and other sensitive equipment attached for long time.Īnd the most important factor here is that there is nothing stopping producers from making a good design. This product will probably have short lifecycle, since running these temperatures is not good for the equipment, even if it can take the temperature getting hot and cold many times in cycles wears things out. This product if used every day on battery, will reduce your battery life, as it will increase they cycle count. This products will reduce the endurance of the battery while connected, ALOT, you can measure it. Seeing ppl in this thread carry different arguments about this or that makes me understand there is plenty of stupid people buying this stuff, and that is how they can keep this garbage on the shelf. Is this acceptabel? NO - this is poor design, and should be removed from shelf by the shops and sent back to manufacturer.

Is this temperature issue normal? NO - this does not happen when plugged in to any other device, and should not happen in this USB-C adapter device either. But after more then 10min in the old Mac there was no increase of heat noticable. I removed it and put it in my old Macbook Pro to see if it was the stick who had problem. Probably hot enough to do data damage if left for many hours.

And when i left a normal USB memory stick in the adpter for about 5 minutes its was REALLY hot when i removed it. This adapter i have cost about $100 in the store. This is probably in chip design, and also on PCB layout design, might also be drivers but about that i dont know. It should have minimum current draw during this resting state.Īll these examples of USB-C hubs getting hot is really poor design from producers. A product that is not in use, even if connected, should not generate any heat.

But having a USB hub that gets even +1 degree C warmer during NO USE AT ALL is a defective product design.

I just bought at SATECHI USB-C to HDMI / Ethernet / USB hub. For me i get one point clear, its obvious that there is alot of people posting in threads like this who really dont have a SINGLE clue what they talking about.
