The next power supplies from Apple are expected to be smaller. According to Digitimes, Navitas Semiconductor is expected to receive an order from Apple for power supplies with GaN (gallium nitride) technology in 2021.
Using GaN should allow Apple to have smaller USB-C power supplies in the future. This should also allow for better efficiency, especially with a block that heats less. Some brands, including Anker and Belkin, are already using GaN for their power supplies. Xiaomi, Dell and Lenovo also use this.
Navitas is the creator of GaNFast, a gallium nitride solution that the company claims can be found in some of the world’s most popular high-speed power adapters. Last year the company announced that GaNFast-based solutions include models from 24 to 300W.
It’s true that there are already third-party models out there that are smaller than Apple’s but still deliver the same performance. Suffice it to say that it is remarkable, especially when it comes to transporting them. To see if Apple will be ready in 2021 or if it has to wait until 2022.
The iPhones have been delivered without a power supply since the iPhone 12. There is no reason to change the scenario with the iPhone 13. Smaller power supplies with GaN should therefore only be offered for sale separately.
