The Huawei Wireless Charger was sold primarily by Huawei for the recent Huawei Mate20 Pro phone but the charger should also allow non-Huawei Qi-enabled phones to be charged as well. Note the Huawei charger only enables 15W wireless charging for the Huawei Mate20 Pro and certain Huawei phones. Other non-Huawei Qi-enabled phones will only get 5 watts of Qi Low Power charging from the Huawei Wireless Charger.
The Huawei Wireless Charger has the Qi logo on the back of its box indicating it may have been Qi certified.
The Huawei Wireless Charger comes with its own Huawei SuperCharge based AC power adapter accessory with a separate USB Type-A to Type-C charging cable.
The 40W based Huawei SuperCharger that came with the Huawei Wireless Charger uses its own proprietary SuperCharge charging up to 40W to power the Huawei charging pad. You will need to connect this Huawei Supercharger to the Huawei charging pad in order to keep it charged using 10 watts (5 volts @ 2 amps), 18 watts (9 volts @ 2 amps) and 40 watts (10 volts @ 4 amps) power profiles. The Huawei SuperCharger should also be connected using the supplied USB Type-A to Type-C cable for fastest charging.
For some reason the Huawei Wireless Charger states it supports inputs of 10 watts (5 volts @ 2 amps) up to 24 watts (12 volts @ 2 amps) although its Huawei SuperCharger accessory claims to supply up to 40W using SuperCharge to the Huawei charging pad.
