I want to buy a pen for the MediaPad, but many pens seem to be incompatible with the tablet. Does anyone have a pen for the device and can tell me which works, gladly with link.
Totally does not matter.
You need a capacitive stylus for your tablet. An active pen does not support it.
Models from the Mediapad M5 Lite or M5 Pro would support the active M-Pen from Huawei, but not the normal M5.
