Review on Wireless Charger Xiaomi Mi 20W Wireless Charging Stand, Black by Nguyn Thng Qun  (Chu ᠌

A power supply of at least 2A is required for charging with the device at least turned on. Because of this, it will be able to provide a charging output of up to 5 watts. It will already be able to output up to 10 W when it is equipped with a QC2.0 or 3.0 power supply, and with QC3.0 class B, it will only be able to pour up to 20 W into the phone. To put it another way, the majority of power supply will not be able to deliver the 20 W as advertised. In certain circumstances, such as the pitaka magnetic case and other cases of a similar nature, it will not be charged since the case contains metal plates. When charging AirPods (in order for them to reach the coil, you need to add something), the charger will occasionally go into error and begin blinking. In general, fairly acceptable for the price that they pay.
