Questions about Satechi Qi Charging Pad ST-WCPR

No, as far as I know, the Huawei P20 Pro does not support wireless charging and therefore does not work with a Qi pad.

Yes.

Good day This can be the case with Quick Charge 2.0, provided that it remains within reasonable limits. If you can no longer touch the device because it is so hot, then I would take a closer look.

No. I've had this charging pad for a year and use it for my iPhone 8. Charging works well, but you have to place the iPhone quite accurately. It has happened to me a few times that the iPhone was not charged because I had not placed it neatly in the middle of the pad. It also has a blue LED that changes to green on other devices when the device is charged. But this does not work on an iPhone (it also says so on the manufacturer's website). The LED stays blue and the device continues to charge, so I don't know if that's good for the battery in the longer term. The LED is also so bright that I had to tape it off (the charging pad is in the bedroom). The workmanship and design are good, but because of the points mentioned above, I don't recommend the charging pad for an iPhone.

Yes, it works. The iPhone X is explicitly listed as "compatible" on the manufacturer's website.

No idea how much power this part delivers in almost charging mode. Sorry!

No. An adapter is not included in the scope of delivery. I recommend using the adapter of your FastCharge smartphone.
