It is reported that Apple's official website stopped selling the 30W USB-C power adapter launched since 2018 this week, but the charger is still included with the 13-inch MacBook Air basic model and Apple Vision Pro.

For the past 7 years, the 30W USB-C adapter has been a common accessory for Apple's lightweight devices, and it is powerful enough to meet the daily charging needs of MacBook Air and a variety of iPads. The suspension of sales may be related to Apple's new generation charging product layout, but the official did not explain this.
