Xiaomi has bumped up its Qi Wireless Charger to offer one of the fastest wireless charging up to 20 watts. Note the Xiaomi Qi charger only enables 20W wireless charging for certain Xiaomi phones like the Xiaomi Mi 9. Other non Xiaomi Qi-enabled phones can only get 5 watts of Qi Low Power charging using the Xiaomi Qi Wireless Charger.
The Xiaomi Qi Wireless Charger sports the Qi logo on the back of its box claiming to be Qi certified with 20W wireless charging support. The Qualcomm Quick Charge logo on the box also indicates the Xiaomi charger supporting Qualcomm Quick Charge based input charging meaning the charger can negotiate with a Qualcomm Quick Charge based charger for own power supply. Note that it does not seem to display the proper Quick Charge logo.
The Xiaomi Qi Wireless Charger comes with its own AC power adapter accessory with a separate USB Type-A to Type-C charging cable and documentation.
The Xiaomi Qi Wireless Charger uses a USB Type-A based Qualcomm Quick Charge 3.0 enabled charger for up to 20 volts charging in, supporting power profiles of 15 watts (5 volts @ 3 amps), 27 watts (9 volts @ 3 amps), 27 watts (12 volts @ 2.25 amps) and 27 watts (20 volts @ 1.35 amps).
Note if you happen to look for a AC charger to quickly charge your Xiaomi phones, you can opt for the 27W QC3 Charger by Xiaomi to get up to 27W power supply through Qualcomm Quick Charge 3.0 standard.
