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).
