The Huawei SuperCharge charger uses Huawei's own SuperCharge technology to charge the Huawei Mate 9 and Huawei P10, but let's see how well it works with the Google Pixel which supports USB Power Delivery technology. Huawei SuperCharge technology can supply up to 10 watts (5 volts @ 2 amps) to phones which don't support SuperCharge.

When we first connected the Google Pixel with the Huawei SuperCharge using the USB Type-A to Type-C cable that came with the charger, the phone took almost 2 hours to fully charge from a fully depleted battery. Note no USB Power Delivery contract was established given that the USB Type-A connector generally doesn't support USB Power Delivery. 

During the initial plug in the Google Pixel from zero charge started off drawing 5 watts (5 volts @ 1 amps) from the Huawei SuperCharge. After 2 minutes, the Google Pixel started to draw 10.5 watts (5 volts @ 2.1 amps) from the Huawei charger. After 54 minutes of charging we turned the phone on and while the phone was active the Google Pixel charged by pulling 8.5 watts (5 volts @ 1.7 amps). The current pulled then started to go down in the next 20 minutes from 1.7 amps to below 0.5 amps at 5 volts as the phone's battery filled up.

Overall it took about 120 minutes to fully charge the Google Pixel with the Huawei SuperCharge. While the Google Pixel only managed to pull power at most 10.5 watts over the entire power charging cycle, the phone is still able to charge with the Huawei charger despite the phone using USB Power Delivery and the Huawei charger uses SuperCharge technology for fast charging. In fact the Google Pixel can charge at a higher power with the Huawei SuperCharge than using its own USB Power Delivery based charger.
