MagSafe for iPhoneĪpple also has MagSafe technology for the iPhone, but it works differently. The MagSafe 3 charging cables are not compatible with any other Macs, including older Macs that used MagSafe 2. MagSafe 3 charging capabilities are available for the 14 and 16-inch MacBook Pro models introduced in 2021 and the 2022 MacBook Air. The lower-end 14-inch machines ship with a 67W power adapter but can take advantage of a 96W power adapter, while the higher-end 14-inch machines ship with the 96W adapter. It's only 16-inch MacBook Pro models that max out at 140W, but the 14-inch machines also use MagSafe charging for cohesiveness.

16-inch MacBook Pro models can still be charged with USB-C cables, but not at the full 140W. When a MagSafe to USB-C cable is paired with the 140W USB-C Power Adapter that comes with the 16-inch MacBook Pro, the MacBook Pro can be charged at up to 140W, and it powers up quicker than it would with a USB-C based charging solution limited to 100W. Maximum Charging PowerĪpple transitioned to MagSafe largely for the 16-inch MacBook Pro, which is now able to charge at up to 140W, a charging speed not supported by USB-C cables. There's a USB-C port at the other end of the charging cable that is meant to plug into a power adapter to power the Mac. There's a small rectangular magnet-topped charging connector that fits into the five-pin charging slot, with the magnets securing the fit.

The new iteration of MagSafe for Mac is officially known as MagSafe 3, and it works exactly like the previous MagSafe implementation.

MagSafe, as the name suggests, uses magnets to connect a charger to a charging port on the Mac, with the idea that if a MagSafe cable is pulled, it disconnects safely without pulling the MacBook down from wherever it might be resting.Īpple swapped from MagSafe to USB-C in 2016, but at this point, the Mac's power needs have exceeded what's possible with USB-C, so Apple needed another solution, and that solution was a return to MagSafe charging. MagSafe for Mac is not a new technology, and it was previously used starting in 2012. The two MagSafe capabilities aren't related, but Apple is using the same MagSafe terminology for all of its latest charging technology.Īpple reintroduced MagSafe for the Mac with the launch of the 2021 14-inch and 16-inch MacBook Pro models, and we can expect to see MagSafe roll out across the Mac lineup. There are MagSafe charging pucks for the iPhone, and MagSafe 3 charging ports and cables for Apple's Macs. MagSafe is now a universal name that Apple uses for both iPhone and Mac charging.
