On the 14-inch MacBook Pro, these ports can be used for fast charging but fast charging the 16-inch MacBook Pro requires using MagSafe 3 and the 140W adapter because the Thunderbolt 4 predates the USB-C PD 3.1 standard and tops out at 100W. My colleague Sean Hollister, for example, has a Dell dock that outputs 130W, but it won’t work with other laptops because there previously wasn’t an open standard to support it.Īs well as its use of the USB-C PD 3.1 standard, Apple also confirmed that the brick is its first gallium nitride (GaN) charger, which means it’s using the material that allows companies to build higher-powered chargers that are smaller in size than their traditional counterparts.Īs well as the specs of the charging brick, Apple also confirmed that any of the new MacBooks’ Thunderbolt 4 ports can be used to charge the laptops. That hasn’t been the case with some USB-C laptop fast chargers in the past, which have had to go off-spec to offer charging speeds over 100W (the previous cap on the USB-C Power Delivery spec). The 140W charger has a single USB-C port. It also means that MacBook owners have the flexibility of using compatible third-party charging bricks with the new MacBooks. Using the USB-C PD 3.1 standard means Apple’s new charging brick will be cross compatible with other devices that use the same power delivery standard, which was announced earlier this year alongside the USB Type-C Release 2.1 specification. Meanwhile, the new 14-inch MacBook Pros come with 67W and 96W chargers, depending on the exact model. As well as being included with the new 16-inch MacBook Pro, the brick is available separately for $99 (not including the USB-C-to-MagSafe cable, which costs an extra $49). Apple’s new 140W charging brick, which works with a new MagSafe charging cable to power the new 16-inch MacBook Pro, uses the USB-C Power Delivery 3.1 standard, Apple has confirmed to The Verge.
