The Huawei Mate 10 Pro uses its own proprietary SuperCharge charging scheme like any other Huawei phones but fortunately the Mate 10 also supports standard USB Power Delivery 2.0 technology to expand its charging options. To demonstrate this we used the Anker PowerCore 13400mAh Nintendo Switch Edition PD Portable Charger to supply power to the Huawei Mate 10 Pro while the phone's battery was completely drained. The Anker power bank supports 22.5 watts based charging equivalent to the Mate 10's own Huawei SuperCharge charger but using USB Power Delivery over Type-C instead of Huawei SuperCharge over Type-A.  

After connecting both phone and power bank using a USB Type-C to Type-C cable, we could see the voltage began on a 5 volts rail as current was being pulled close to about 1 amps. The phone was initially charging at around 4.1 watts (5.1 volts @ 0.8 amps) over the first 80 seconds after which a hard reset happened and the current briefly dropped to near zero. The current quickly resumed to about 0.8 amps while the voltage rose up to a 9 volts rail. At this point the phone drew mostly around 7.3 watts (9.1 volts @ 0.8 amps) power but later pulled higher current to settle out charging at about 17 watts (9 volts @ 1.9 amps) with the power bank. Click here to download the trace captured by the GRL-A1 power analyzer to see more details.

The Huawei Mate 10 Pro was able to charge properly with the Anker PowerCore 13400mAh Nintendo Switch Edition PD Portable Charger over USB Power Delivery despite not reaching max 22.5W.
