There are two main power supply connections for the Type-C interface: USB Power Delivery (USB-PD) and Quick Charge (QC). USB-PD is a charging protocol based on the USB Type-C interface, which supports bidirectional charging, multiple voltage and current outputs, and high charging efficiency; QC is a fast charging technology launched by Qualcomm and is widely used in various mobile devices Medium, charging speed is fast.
USB Power Delivery (USB-PD) power supply connection method
USB-PD is a charging protocol based on the USB Type-C interface. It supports bidirectional charging and multiple voltage and current outputs, and can provide an efficient and safe charging experience for various devices. The USB-PD protocol defines a variety of voltage and current combinations, which can be intelligently matched according to the needs of the device to achieve fast charging. In addition, USB-PD also supports the function of charging and playing at the same time, which can provide power to the device while charging, improving the battery life of the device.
In practical applications, when using the USB-PD protocol for power supply connection, you need to pay attention to the following points: first, you need to choose a charger and cable that support the USB-PD protocol; second, you need to ensure that the device also supports the USB-PD protocol; finally, It is necessary to follow the instructions of the equipment for correct connection and operation.
Quick Charge (QC) power supply connection method
QC is a fast charging technology launched by Qualcomm and is widely used in various mobile devices. QC technology uses a unique charging algorithm and circuit design to quickly charge devices in a short period of time. QC technology continues to develop, and multiple versions have been launched so far, with charging speed and efficiency constantly improving.
In practical applications, when using QC technology for power supply connection, you need to pay attention to the following points: First, you need to choose a charger and cable that support QC technology; second, you need to ensure that the device also supports QC technology; finally, you need to follow the instructions of the device. Proper connection and operation. In addition, it is also necessary to note that different versions of QC technology may have compatibility issues and require corresponding adaptation and adjustment.
The Type-C interface power supply connection method has a variety of advantages and application scenarios, and can meet the charging and data transmission needs of various devices. In actual applications, it is necessary to select the appropriate power supply connection method according to the characteristics of the device and interface, and perform correct connection and operation.
