The MacBook Air M1 at the end of 2020 is the first Air series computer equipped with Apple's self-developed M1 chip, and the appearance of the new MacBook Air M1 has not changed much, and the side is still 2 USB4 interfaces, supporting data transmission, fast charging, and video transmission.
Apple equipped the MacBook Air M1 with a 30W PD fast charging head, but in the actual measurement of the charging head network, it seems that the 30W fast charging power cannot meet the power needs of the MacBook Air M1.
Charging compatibility testing
Yes, that's right, the Apple 5W charger can also charge the MacBook Air M1, of course, the power is only 4.7W.
Swap apple 18W PD charger to charge the MacBook Air M1, triggering a 9V PD fast charge gear with a power of 17.07W.
Charge the MacBook Air M1 with an Apple 20W PD charger at 19.19W.
Charge the MacBook Air M1 with an Apple 30W PD charger with 28.63W.
Charge the MacBook Air M1 with an Apple 61W PD charger with 40.83W of power.
Full test of charging
Above we have tested, Apple 5W to 61W charger can be MacBook Air M1 fast charging, let's take a look at the charging of the whole process of measured data.
In the actual test of the whole charging process, the MacBook Air M1 was first charged with an Apple 20W PD charger, and the power was in the input state of 19W 2 hours and 44 minutes ago, and then began to decline, and the charge ended in 3 hours and 28 minutes.
Replace the charger with the Apple 30W charger, which is also the standard charger of the MacBook Air M1, which was at 28W input before 1 hour and 18 minutes, and then began to decline, and the charging ended in 2 hours and 40 minutes, which was significantly higher than the charging speed of 20W.
This is the data change of the entire process of charging the MacBook Air M1 using the Apple 67W PD charger, and the whole power drops in a step-by-step manner, divided into four stages, and finally ends at 2 hours and 17 minutes.
Replace the charger with apple 96W PD charger, the whole test process can be roughly divided into four stages, charging ends in 2 hours and 18 minutes, compared with Apple's 30W charging time is also significantly shortened.
Finally, apple 140W gallium nitride charger was used to charge the MacBook Air M1, and the entire test process also went through four stages, ending in 2 hours and 20 minutes.
The five kinds of charging are drawn into a curve chart, and the overall difference is still very obvious. The first is the curve of the 20W charger, 1 hour charge 33%, 2 hours charge 65%, full takes 3 hours and 28 minutes, this standard iPad charger is still a little weak in the face of the MacBook Air.
As a standard 30W PD charger, half an hour charging 26%, 1 hour charging 52%, fully charged takes 2 hours and 40 minutes, but this is not the optimal solution. As can be seen from the curve chart, the 67W, 96W, 140W charging curves almost coincide, half an hour charging about 41%, 1 hour charging about 70%, fully charged takes about 2 hours and 18 minutes, compared to the MacBook Air standard 30W PD charger is faster, especially in the half hour and 1 hour time point is more obvious.
Charging head net summary
The above for everyone to test the different power size of the charger for the MacBook Air M1 charging the whole process of data changes, as a representative of lightweight laptop, MacBook Air has a thin and light body, M1 blessing makes its battery life more durable, equipped with USB-C charging interface and support USB PD fast charging.
A total of five different power sizes of chargers for the MacBook Air M1 charging data, overall, 20W PD charger can charge the MacBook Air M1, but obviously can not meet its fast charging needs; the original 30W PD charger will be faster, but there is still a lot of room for improvement; 67W and above PD charger for the MacBook Air M1 charging can get considerable fast charging effect. I believe that at this time, there are readers who want to ask, why not test the 65W, after all, there are so many 65W Gallium nitride chargers now. Quite simply, the chargers used in this test are all Apple's own fast charging products.
For the fast charging of the MacBook Air M1, if you are not in a hurry, you can choose the original 30W PD charger to use, but if you want to quickly restore the power in a short period of time, you can consider using a 67W and above PD charger.
