MacRumors: “MagSafe Charger only charges at Full 15W Speeds with Apple’s 20W Power Adapter”

YouTuber Aaron Zollo of Zollotech tested several first and third-party power adapter options with the iPhone 12 Pro and a MagSafe charger using a meter to measure actual power output. Paired with the 20W power adapter that Apple offers, the MagSafe Charger successfully hit 15W, but no other chargers that he tested provided the same speeds.


For maximum charging speeds with the MagSafe Charger and an iPhone 12 or 12 Pro, Apple’s 20W power adapter is required, and older power adapter options won’t work as well. Third-party companies will need to come out with new chargers that use the particular power profile that Apple is using to provide the optimum amount of power before a third-party charger will be able to provide the full 15W with the MagSafe Charger.

Apple MagSafe – Which Charger is Fastest – Speed Test

Some might call this ‘confusing’, I prefer to call it as it is: another display of hypocrisy and greed on the part of Apple. Unless you buy the newest model from Apple, the charging speeds you get are significantly reduced – so much for the narrative that removing chargers from the iPhone package is meant to reduce environmental impact because people already have power adapters from other devices.

This sounds like it will all work great, but now I have a new phone, two new cables, and one new charging brick, but I didn’t get a charging brick with the iPhone because that was supposed to help reduce waste?

You got it. Thanks for buying the things our ads say you should buy, and enjoy your new iPhone.

And a giant middle-finger to Android users:

The same goes for Android phones. The MagSafe Charger technically supports Qi-based charging and can work with Android devices, but when paired with an Android smartphone, the MagSafe charger was outputting at 1.5W, which is slow enough that it’s nearly useless.
