As everyone knows, Apple has supported PD fast charging since the iPhone 8. But what is PD fast charging, are you clear?
PD is a fast charging standard developed by the USB-IF organization. The obvious advantages of the following three points are enough to be the reason for Apple to choose it.
1 unified for user convenience
The PD standard can support multiple voltages such as 5V, 9V, 12V, 15V, 20V, etc., and can intelligently match voltages according to the needs of different devices such as mobile phones, tablets, and notebooks. In other words, all digital devices such as mobile phones, tablets, and notebooks can be used with a single charging head, which is undoubtedly greatly convenient for the user's daily use.
2 charging speed to force. Under the USB PD power transfer protocol, the maximum output voltage is 20V, and the output current is 5A, which means that the current can be transmitted up to 100W.
3PD fast charging and unification is an industry trend
According to statistics, as of March 2019, the number of members of the USB-IF organization has reached 1,020, and more than 20 models on the market have adopted PD fast charging. In addition to Apple's mobile phones, Huawei, Samsung, Xiaomi, Nokia, Hammer, Sony, Meizu, Razer and many other mainstream mobile phones have also incorporated the PD fast charge protocol into the charging configuration of mobile phones.
It is believed that under the driving of Apple's mobile phone, which is one of the wind vanes of the mobile phone industry, there will be more brand mobile phones supporting PD fast charging, and PD fast charging is undoubtedly an industry trend.
