It appears that Apple would likely launch a 30W GaN charger later this year. Kuo also said that the device would probably have a 'new' form-factor, although he didn't reveal anything else about it at that time.
As for the new charger that Apple is developing, its 35W output is fast enough to charge most of Apple's current mobile products, including the iPhone 13 Pro Max, which can charge at up to 27W. The dual USB-C ports also mean that s could also use it to charge multiple devices simultaneously, like an iPhone and an Apple Watch.
Apple this week published a document on its website, revealing that it is prepping the launch of a 35-Watt dual USB-C charger. The page has since been taken down, but not before 9t05Mac got a screenshot and copied much of the content. The now-defunct page reportedly had directions on how to use the power adapter, including basic tips on connecting it to the device that needs to be charged. As noted by the blog, if the adapter makes it to the market, it would mark the first time Apple has released a dual USB-C charger of any kind.
Apple's Plans For A Standalone GaN Charger
There's no more information about the charger itself, but this isn't the first time the media has reported on Apple's plans to launch a GaN charger this year. While the official document never identified the leaked product as a GaN charger, the report speculates that it will likely come with the GaN technology. That's because multiple reports from different sources over the past several months have claimed that Apple is working on a GaN charger. Apart from Kuo's claim mentioned above, the Taiwanese publication Digitimes last year also reported that Apple was developing new GaN chargers with USB-C connectivity. However, it did not say anything definitive about the launch date.
For those wondering, gallium nitride (GaN) chargers are more power-efficient than last year's 16-inch MacBook Pro. However, the latest developments suggest that it might not remain the only one for much longer.
