If you happen to lose the charger that comes with your Google Pixel, you can still charge the phone quickly using other USB Power Delivery chargers like the Xiaomi MiBook Charger that is supplied with the Mi Notebook Air 13.3".

From the USB Power Delivery negotiations, we can see how well the Xiaomi MiBook Charger powers the Google Pixel on a well charged battery. When directly connected with a USB Type-C to Type-C cable, the charger can be seen to offer an initial 10 watts (5 volts @ 2 amps) charging power to the Google Pixel. 

The Google Pixel goes on to establish a 10 watts (5 volts @ 2 amps) power contract with the Xiaomi MiBook Charger.

Later the charger is also seen to follow up with four other power profiles of 18 watts (9 volts @ 2 amps), 24 watts (12 volts @ 2 amps), 45 watts (15 volts @ 3 amps), and 65 watts (20 volts @ 3.25 amps) in addition to the initial 10 watts (5 volts @ 2 amps).

We then observe that the Google Pixel requests to draw 18 watts (9 volts @ 2 amps) which the Xiaomi MiBook Charger accepts.

With the Google Pixel's battery being already well charged, the phone is observed to start pulling about 9 watts (9 volts @ 1 amps) at the beginning before it eventually charges at 4.5 watts (9 volts @ 0.5 amps).

We can confirm that the Xiaomi MiBook Charger can work well together with your Google Pixel over USB Power Delivery.
