I have a SutechSmart USB Type-C Hub Pro and I use it to connect my iPad mini 6 to a TV via HDMI cable and everything works great. But if I plug in a charger in to an USB-C port on the hub to keep the battery from draining, my iPad mini 6 gets very hot while gaming. To be clear, iPad mini does not get hot while it's not plugged in to a TV even though it's plugged in to a charger. iPad mini also doesn't get hot while using screen mirroring on to a tv, playing same game/s and plugged in directly in to a charger. The Hub doesn't get hot, but warm as it always has in the past, which I consider normal.

Ive used same hub on my Windows laptop many times with no issues with two monitors connected via HDMI, and connected a USB-C 65W charger to charge a laptop. I used same Hub with my 2014 MacBook Air as a LAN adapter, connected to my router via USB-A to USB-C adapter with no issues.

When I don't plug in a charger in to the USB-C on the hub while it's connected to a TV via HDMI, iPad mini doesn't get hot at all, but the battery gets drained quite fast.

Im using an USB charging port on an Anker power strip.

Should I get a different Hub or is this a common issues with this type of setup?

Cheers.

edit:

I switched to an Apple 12W charger from my old iPad and the temps have been better after half an hour, but still a lot warmer when im not plugged in to a tv.

Second edit:

The USB charging ports on the Anker power supply were causing the issues. After using Apples 12w charger for two hours, the temps are much much lower. But I'll stick to Screen Mirroring from now on as it doesn't cause as much load on the iPad and keeps it much much cooler, and the picture quality still great for playing games.

The iPad's is providing video to two displays. You’re charging the battery. And you’re playing a game. I think it's just naturally going to get warm.

If the iPad gets too hot, I believe it’ll tell you that it needs to cool down before you can operate it again.

But after seeing your edits, maybe your iPad was just trying to pull too much power from your 3rd party power supply.

The USB ports on Anker power strip are the root cause of the issue, even internet would go down on iPad when its plugged in to it. But it works fine with a stand alone charger/s and it runs much cooler. It was the first time I was using the USB ports on the power strip despite owning it for several years. I guess I should have tested it when I bought it. Oh well.

The other week I had to return Anker Outlet Extender (9-in-1) because the USB ports don't work correctly, so it seems to me that Anker can't make them correctly. I know it works for some people but I've had no luck.

Cheers.

Yeah. My motto is if you want to protect your battery, pay the Apple tax. I know it’s not always an option.

Yeah I have no issues with their GaN chargers but I haven't used any of their power strip products. Generally I avoid products that combine functionality like power strips that have integrated chargers in them; my logic being that I prefer products whose designers are focused on the specific purpose of the product and are not cutting corners on achieving each of its features to make an overall product affordable. As Anker has expanded their product lines there's more things I just am not interested in buying from them.

Glad OP figured it out. Whenever I get a new USB charger I will test it using an inline power meter to see what charging voltage and current it's negotiating with the device. They're rather inexpensive and can be handy for investigating charging issues.
