Apple’s MagSafe Duo Charger Can’t Charge iPhone 12 At Full 15W

Apple’s MagSafe Duo Charger isn’t yet available to buy but Apple says that it’s coming soon. But you might not want to buy the $129 charger for a couple of reasons, and that price is only one of them.

As spotted by Bloomberg’s Mark Gurman earlier today, the new charger can’t actually charge an iPhone 12, iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max at the maximum 15W allowed by the MagSafe specification.

Instead, it can only charge at a maximum of 14W. And even then, only if you pair it with a 27W or higher USB-C charger.

It’s worth noting at this point that Apple doesn’t ship the MagSafe Duo Charger with any adapter at all, and it doesn’t even sell a 27W charger, but a 30W one.

Here’s what Apple’s store page has to say about it.


-20W USB-C Power Adapter (sold separately) for faster wireless charging up to 11W
-27W or higher USB-C Power Adapter (sold separately) for faster wireless charging up to 14W

The differences between charging at 14W and 15W are minimal, of course. And it’s likely the extra power is being used to charge an Apple Watch seeing as the charger can power the two devices at once.

It’s still an interesting point, however. And one that will make the new wireless charger particularly costly depending on the power adapter you decide to pair it with.
