Now let's look at how the Apple 13" MacBook Air (2020) can actually take advantage of higher than 30W by using the GRL-C2 USB PD Tester to emulate a 60W USB PD charger, This extended post "100%" battery charging could explain why the Apple 13" MacBook Air (2020) reports staying at 100% battery for about 13 minutes before the battery appears to start discharging.

Interestingly, we see that the Mac still appears to be charging for another 25 minutes after the Mac has reported 100% battery.

Using the GRL-C2 USB PD Tester and GRL-PSP Power Analyzer software from Granite River Labs, we can see it takes about 2.8 hours for the Apple 13" MacBook Air (2020) to report 100% battery, after starting to charge at close to 0% battery.

This Mac ships with a small Apple 30W USB-C Power Adapter. However, if you are running power hungry applications, 30W seems a bit low given that a lot of tablets are already in this range and even smartphones have started charging above 30W.
