I'm considering buying the REDMI Pad 2 11-inch (2025), Helio G100-Ultra, Wi-Fi, 4GB/128GB, for a wired touchscreen control panel.
Has anyone actually tested a USB-C hub with PD pass-through charging on this exact tablet, while a wired USB mouse, keyboard, USB drive, or USB serial device keeps working?
The required setup is:
PD charger -> hub PD input
USB peripheral -> hub USB data port
Hub host cable -> tablet's single USB-C port
The tablet needs to remain the USB data host while receiving power. Xiaomi's official documentation confirms OTG and PD 2.0 charging separately, but I haven't found a test confirming that combination.
If you've tried it, could you share:
- Whether the peripheral kept working while the tablet charged, and whether the battery percentage increased with the screen on.
- The hub model, charger model, and HyperOS version/build, if available.
- If measured: did it work at 5V, or did the tablet negotiate 9V? Results without a USB power meter are still very helpful.
Please specify the exact tablet model. This question concerns the 11-inch G100-Ultra version; the Pad 2 Pro, Pad 2 9.7-inch, Redmi Pad SE, and older Mi Pad 2 have different hardware.

Thanks for any first-hand results, including combinations that did not work.
