Introduction

Apple launched a new MagSafe charger to replace the old MagSafe charger launched four years ago. The appearance has not changed much, except that the cable has been changed to a woven one, which is more durable.

Today, ChargerLAB will use this new charger with the iPhone 16 Pro Max to conduct a wireless charging test to see what the actual charging power can reach.

Wireless Charging Test of New MagSafe Charger with iPhone 16 Pro Max-Chargerlab

Apple's official website claims that when it is paired with a 30W charger, it can provide 25W of wireless output power, which can charge the iPhone 16 and iPhone 16 Pro to half capacity in 30 minutes.

It comes in a white box with the Apple logo and product appearance.

The specs info is posted on the bottom of the box: length 1m, model: A2580.

The box contains the MagSafe charger and some documents. It uses a woven cable, and the magnetic module is smaller and thinner.

It can support input of 5V3A, 9V3A, and 15V3A.

We will use an iPhone 16 Pro Max for testing, with iOS version 18.0.

Wireless Charging Test

In addition to supporting 25W MagSafe charging, the iPhone 16 Pro Max also supports Qi2 15W wireless charging and Qi 7.5W wireless charging.

Using an Apple 30W charger and the new MagSafe Charger to charge the iPhone 16 Pro Max, the measured input power is about 14.96V 1.94A 29.03W. Excluding losses, the wireless charging power is about 25W.

Full Charging Test

Next, we'll use the MagSafe Charger with an Apple 30W charger to fully charge the iPhone 16 Pro Max. And put them into a 25°C (77℉) thermotank throughout the test.

The voltage is around 15V at first, and the charging curve can be divided into five parts. In the first part, the peak power stays at 29W for the first 5 minutes. Then, the power gradually drops to 21W, 10W, and 4W in turn. At 39 minutes, the voltage drops from 15 V to 9 V briefly and then increases to 15 V. At 55 minutes, the voltage drops from 15 V to 9 V. The final part begins at one hour and 16 minutes, the power slowly drops to almost zero. During this process, the voltage drops to 5V. It takes 2 hours and 23 minutes to be fully charged.

We also turn it into another curve. The new MagSafe Charger can charge the iPhone 16 Pro Max to 50% in 34 minutes. And it can reach 80% in 1 hour and 10 minutes, 100% in 2 hours and 23 minutes.

Temperature Test

Since wireless charging generates a lot of heat, temperature is something everyone is concerned about. So, we recorded the highest temperature on the front and back after charging for 15 mins, 30 mins, and 50 mins.

After 15 mins of charging, the maximum temperature of the contact surface between the phone and the wireless charger is 41.2℃ (106.16 ℉). At this time, the charging power is about 21W.

After 30 mins of charging, the maximum temperature is 39.4℃ (102.92 ℉).

After 50 mins of charging, the maximum temperature is 39.3℃ (102.74 ℉). At this time, the charging power is about 10W. Compared with the temperature at the 15th minute, the temperature dropped by about 1.9°C, but it was still relatively high.

Summary of ChargerLAB

Within 31 minutes, the new MagSafe Charger can maintain a charging power of 21 to 29W. The full charging time is 2 hours and 23 minutes, which is similar to the previous generation. As for the temperature, it was maintained at 39.3-41.2°C within 50 minutes. It’s similar to other magnetic wireless chargers, but it has higher power, so it performs well.
