Adapter PD fast charging technology, full name is Power Delivery (PD), is a fast charging standard formulated by the USB-IF(USB Implementers Forum) organization. The core of this technology is to achieve an efficient and safe charging experience through intelligent adjustment of voltage and current. PD fast charging technology not only supports high-power charging, but also has a wide range of compatibility to meet the fast charging needs of various electronic devices.

## The working principle of 2. PD fast charging technology

The working principle of PD fast charging technology is mainly based on the intelligent adjustment of voltage and current. During the charging process, the device will communicate with the charger to inform it of the required voltage and current. After receiving this information, the charger will intelligently adjust the output voltage and current to meet the charging needs of the device. This intelligent adjustment method enables PD fast charging to reduce energy consumption and heat generation during charging while ensuring the charging speed.

PD fast charging adopts a communication protocol based on the USB-C port, and realizes the accurate matching of charging parameters through the information exchange between the device and the charger. The charger can provide different voltages such as 5V, 9V, 15V, 20V, etc., and different currents such as 0.5-2A, 1-3A, 3-5A, 5-10A, etc. according to the requirements of the equipment, so as to achieve a maximum charging power of more than 100W.
