Question about Atra 6in1 Type C Stroke

Only one USB Type C

Is it not possible to edit the comments? I wanted to say that I tested this on the IPad Pro 11 inch (2018) :)

I have tested the following: HDMI to monitor, SD card, headphones via jack plug, USB storage device. Everything worked at the same time, I could access both the SD card and the USB storage device via the Files app. The screen was mirrored on the monitor and I could listen to music via the headphones. Unfortunately, I didn't have a micro SD card handy to plug in, but I assume that would work :)
Since I don't have a USB-C storage device, I could only test whether it could be charged at the same time, which was no problem :)
