American manufacturing giant, Apple, has since released a 30W charger with model number MR2A2LL/A. However, in a surprising turn of event, this charger was taken off the shelf. The company then released a new 30W USB-C power adapter with model number MY1W2AM / A. However, at first glance, there is no difference between these chargers. If there is no difference, why discontinue the former and release the lattter?
Well, there is actually a little difference between the two chargers. According to a recent comparison report, the new version (MY1W2AM / A) is compatable with more devices. According to the report, there is no essential difference between the new and old Apple 30W chargers. The new model is slightly thicker than the old one. Both support the PD 2.0 protocol. The charging gears are 5V/3A, 9V/3A, 15V/2A, 20V/1.5A.
The difference is that the PD compatibility of the new 30W USB has been improved. The charging head net claims that Apple’s new 30W charger can work with most popular devices. The Apple 30W USB‑C Power Adapter offers fast, efficient charging at home, in the office, or on the go. While the power adapter is compatible with any USB‑C–enabled device, Apple recommends pairing it with the 13-inch MacBook Air with Retina display for optimal charging performance. You can also pair it with select iPhone and iPad Pro models to take advantage of the fast-charging feature.
