When connected to a 60W USB PD charging source, we can see that the Apple 13" MacBook Air (2020) actually pulls a maximum of 47.5W for much of the 0 to 70% battery charging period. Initially the Mac max temperature on its surface gets up to a hot 50 deg C but settles to 40 deg C later.Īfter 70% charge, the Apple 13" MacBook Air (2020) starts to reduce its power to help improve battery life, and it takes about 104 minutes to fully charge the Mac.Īfter the Apple 13" MacBook Air (2020) is fully charged, the Mac uses just 14-22W while the Mac display is on without any significant power hungry applications consuming power. When Time Machine is used for backup, the Mac power consumption increases to 17-33W. 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. During this time, the Apple 30W USB-C Power Adapter gets quite hot, reaching and uncomfortable 63 degrees C. 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.

The Apple 13" MacBook Air (2020) is a great option if you need both affordability and portability ( or just want to avoid the Touch Bar).
