See this white brick? It provides a measly 30W of power for a single device, but Apple charges $50 for it. Please don’t buy one because we now have solid evidence that Apple is about to replace it with something much, much better – a 35W charger with two gates, likely powered by gallium nitride (GaN) technology that can also make it smaller.
That’s the word of 9to5Mac, who got this particular piece of information from by far the most trusted source of Apple leaks: Apple’s own website. Apparently, the company accidentally threw a support document live for an “Apple 35W Dual USB-C Port Power Adapter”, and 9to5 managed to take a screenshot before pulling it.

This is likely the “about 30W” GaN charger that analyst Ming-Chi Kuo tweeted last month, which he said would have “a new form factor design” and arrive in 2022.
You could quickly charge an iPhone 13 Pro Max and an Apple Watch at the same time with that power, or an M1 MacBook Air and a watch, or an iPad and an Apple Watch, or a pair of iPhones, or an iPad Pro and an iPhone in one. slower pace, or… it’s USB-C, so there’s a lot of options.
It wouldn’t be Apple’s first GaN charger — that would be the 140W power adapter that came with the new 16-inch MacBook Pro. But unless I’m mistaken, it would be the first two-port charger Apple has ever made and certainly the first with USB-C.
In fact, there is a double USB-C shaped hole that seems to be waiting for it in the Apple Store. Apple has Belkin chargers that: have a single USB-C port and a 32W charger with both USB-C and USB-A portsbut not Belkin’s Dual USB-C Charger — and that’s Apple’s main accessory partner we’re talking about. Of course, you can find quite a few dual-port USB-C chargers outside the Apple Store, including many with faster speeds.
Note that this device would provide 35W in total, not 35W per port. 9to5Mac says the support document states that each port can operate in one of four modes: 5VDC/3A, 9VDC/3A, 15VDC/2.33A, or 20VDC/1.75A. That should easily allow two devices to charge at 15W or one at 27W and one at 5W, but we’ll have to see what combinations of devices could work.
The support document does not suggest when the charger may arrive but does say no USB-C cable is included.
