Through Huawei's proprietary SuperCharge charging scheme, the Huawei SuperCharge MultiPort Charger claims to supply up to 22.5 watts (4.5 volts @ 5 amps or 5 volts @ 4.5 amps) to rapidly charge compatible Huawei phones like the Huawei P10. When tested previously we only observed 15W based charging rather than 22.5W using the Huawei SuperCharge USB Type-C to USB Type-A cable.

Using back the same setup to connect both the P10 phone and charger, this time we also linked up the FLIR C2 Compact Thermal Camera to the charger through the non SuperCharge based port. The FLIR camera was used to capture thermal images during charging while keeping itself charged at the same time. We then observed about 72 minutes of SuperCharge charging to take place starting from a dead battery on the phone.  

From initial plugin the VBUS could be seen to start up on a 5 volts rail as current was pulled below 1 amps. When the voltage transitioned at around 3.7-4.4 volts, the current began to ramp up to settle out charging at about 14.8 watts (4.5 volts @ 3.3 amps). After the first 10 minutes the phone was turned on which saw a decrease in current which then further reduced when the FLIR camera was being used resulting in around 9.9 watts (4.5 volts @ 2.2 amps) charging when approaching 50 minutes. When the battery was half full the current ramped down to almost 1.2 amps and later to about 0.8 amps after the voltage went up to about 5.2 volts. Similar charging could also be seen without connecting the FLIR camera where the power mostly stayed within 15W, which is a lot lower than 22.5 watts.
