Review on Wireless Charger Xiaomi Mi 20W Wireless Charging Stand, Black by Koichiro Takahashi ᠌

To charge at least turned on, you need a power supply from 2A. With this, it will give out up to 5 watts for charging. With a QC2.0 / 3.0 power supply, it will already be able to output up to 10 W and, accordingly, with QC3.0 class B, it will only be able to pour up to 20 W into the phone. In other words, with most power supplies the declared 20 W will not be :) In cases like pitaka magnetic case and similar ones, it will not be charged due to the presence of metal plates in the case. When charging airpods (so that they reach the coil, you need to put something), the charger sometimes falls into error and starts blinking. In general, for their money - quite ok.
