Therefore, the new 30W adapter is the most comprehensive charger in Apple’s history.

Second, Apple’s new 30W and the original 29W power adapter appearance comparison

The dimensions are identical and the shape is slightly different. The main differences are: housing, interface, AC plug. The voltage specification is the biggest difference: 30W specifications are 5V3A, 9V3A, 15V2A, 20V1.5A, with 4 specifications, which is by far the most complete charger for Apple. The specification of 29W is 5.2V2.4A and 14.5V2.0A, and there are only two specifications.

Third, Apple’s new 30W and the original 29W USB-C power adapter comparison evaluation

For the new 30W adapter, the ChargerLab POWER-Z KT001 portable tester was used for USB PD detection and found to support four specifications: 5V3A, 9V3A, 15V2A, 20V1.5A, which are identical to the parameters marked on the manual.

For the original 29W adapter, use the ChargerLab POWER-Z KT001 portable tester for USB PD detection, which only supports 2 specifications: 5V2.4A, 14.8V2A.

The 30W adapter tests the 13-inch MacBook Pro (2017 model) and uses the ChargerLab POWER-Z KM001C portable tester for detection. The charging power is 28.08W (20.02V/1.40A) and supports USB PD fast charging.

The 29W adapter tests the 13-inch MacBook Pro (2017 model) and uses the ChargerLab POWER-Z KM001C portable tester for detection. The charging power is 27.97W (14.73V/1.90A) and supports USB PD fast charging.

Apple’s original 29W USB PD adapter was first launched in 2015 and has a limited scope of application. After three years of development, USB PD fast charging has grown rapidly and formed a complete specification system. It can be seen that the 9V, 15V and 20V of the new 30W adapter are completely normal USB PD specifications. In addition, the new iPhone, which will be released in September this year, comes standard with an 18W adapter.
