MagSafe Duo, priced at $129, can charge iPhone and Apple Watch at the same time, and is small in size, which many people look forward to. And Bloomberg Mark Gurman noticed that Apple recently updated the information on the MagSafe Duo product page. It was found that even if MagSafe Duo uses the 20W USB-C power adapter recommended by Apple, it cannot use 15W wireless charging on iPhone 12, iPhone 12 Pro and iPhone 12 Pro Max (iPhone 12 mini itself can only use 12W at the fastest), and The maximum output is 11W.
If you want to charge faster, you need to use a 27W or above USB-C power adapter to reach 14W output. According to Apple's official website, MagSafe Duo has not yet confirmed its launch time and only shows coming soon.
