- Apple discontinued 29W power adapter will not work with the MagSafe Duo Charger.
In the document, Apple recommends that you use a power adapter of at least 20 watts if you want the MagSafe Duo charger to perform correctly, but also encourages owners to use a higher wattage adapter as well.
It then notes that the 29W power adapter, which was replaced with the 30W power adapter a couple of years ago, will not work with the new wireless charger for the iPhone, Apple Watch, and AirPods.
The company also notes that charging with Lightning accessories, or charging the iPhone and Apple Watch at the same time, will result in slower charging times.
The basic idea is to use at least a 20W power adapter to get fast charging for your iPhone 12 as long as you are charging the phone by itself. The charger is also perfect for charging both the iPhone and Apple Watch at the same time overnight.
