#WHAT WATTAGE CHARGER FOR MACBOOK AIR PRO#
In fact, the new fast charging capabilities on the 16-inch MacBook Pro not only require the 140W USB-C Power Adapter, but can also only run over the new MagSafe 3 port, as the standard Thunderbolt 4 / USB-C ports simply can’t transfer the necessary voltage. New MacBook Pro Fast Charging Requirements These charging speeds have long been supported on the iPhone, of course, but an iPhone battery is also a fraction of the size of the battery found in any MacBook, much less the one that’s the king of all MacBooks. The most powerful charger is particularly important considering Apple’s promise to allow a 16-inch MacBook Pro to fast charge up to 50% in about 30 minutes.
While early rumours suggested Apple would use this to make its iPhone chargers smaller, we can now see that it had something else in mind. While the 140W power brick is still something of a behemoth, it would be considerably larger if Apple were using traditional silicon rather than relying on GaN. What’s particularly notable about the new and more powerful 140W adapter is that it’s the first of Apple’s power bricks to take advantage of the new Galium Nitride (GaN) technology that it’s had in the works since early last year. By contrast, the 14-inch MacBook Pro comes with a 67W adapter in its base $1,999 configuration - the one with the scaled-down 8-core M1 Pro chip - however bumping that up to even the mid-range M1 Pro will net you the 96W USB-C power adapter instead.
