The most controversial point of this new iPhone should be that the iPhone 12 is not equipped with a charging head. I thought it would come with a USB-C charging head that supports PD fast charging like last year. After all, 5V1A really can’t adapt to the current fast charging rhythm, but iPhone 12 is not equipped directly. The charging head is really surprising. So how to choose iPhone12 charging head, how much W is the charging power of iPhone12? Let's follow the mung bean to learn about iPhone12 charging knowledge.

1. What is the charging port of iPhone 12
When choosing the iPhone12 charging head, we need to understand the charging interface and the data line interface of the iPhone12, after all, the interface can be charged only after the corresponding interface.

First look at the charging interface of iPhone12: standard lightning interface (lightning interface). There have been rumors that Apple may use the USB-C interface to replace the lightning interface, because USB-C is almost the most powerful interface at present, supporting multiple audio and video protocols such as USB 3.1, Thunder 3, DP, MHL, and the maximum charging power is 100W , It can also multitask in parallel, and there is a trend of a unified interface. Apple has also used the USB-C interface on some models of MacBook and iPad. However, this time Apple did not equip the iPhone12 with a USB-C interface. There are two main reasons. The first is that the size of the lightning interface is smaller than that of the USB-C. This is an obvious advantage for the iPhone with an inch of space. Secondly, the lightning interface has Apple. A number of patents require a license fee for third-party use and must pass Apple’s MFi certification. This is part of Apple’s revenue. Therefore, the iPhone 12 continues to use the lightning interface as normal operation.

As for the iPhone12 data cable: the new USB-C to lightning fast charging cable. Apple supports PD fast charging from the iPhone8 series. PD fast charging requires a USB-C charging head + USB-C to lightning data cable, which means that the USB-C to lightning fast charging cable needs to be equipped with a USB-C interface charging head Use, so the original charging head of our old iPhone cannot be used with this line to charge iPhone12 (the interface is wrong, except for last year’s iPhone11Pro series). When choosing a charging head for iPhone12, you must choose the USB-C socket and support the PD protocol. In order to quickly charge the iPhone.
