What are the differences between PD charging cables and ordinary charging cables?

The difference between pd charging cable and ordinary charging cable: 1. Charging speed; 2. Current conversion after charging is completed; 3. Voltage and current regulation; 4. Protocol support; 5. Charging protocol; 6. Charging power Density; 7. Heat generated during charging; 8. Openness of charging protocol. Detailed introduction: 1. Charging speed. The PD charging line integrates a quasi-resonant current mode controller and power MOSFET, which has the characteristics of high performance, low standby power consumption, low cost, etc., while ordinary charging lines generally have a charging specification of 5V2A. , using constant current and constant voltage charging, slower charging speed, etc.

There are significant differences between PD charging cables and ordinary charging cables in many aspects.

1. Charging speed: The PD charging line integrates a quasi-resonant current mode controller and power MOSFET, which has the characteristics of high performance, low standby power consumption, and low cost. Ordinary charging cables generally have a charging specification of 5V2A, using constant current and constant voltage charging, and the charging speed is slow.

2. Current conversion after charging is completed: The chip on the PD charging line can control the charging process and automatically stop charging once it is full, making the entire charging process safe and efficient. The ordinary 5V2A charging standard cable usually automatically switches to trickle charging state after the battery is fully charged.

3. Voltage and current adjustment: PD standard supports multi-level voltages such as 5V, 9V, 12V, 15V, 20V, etc., which can be adjusted according to the requirements of various devices such as mobile phones, tablets, and laptops. Intelligent voltage adjustment is required. In other words, all digital devices such as mobile phones, tablets, and laptops can share a charging head, which undoubtedly greatly facilitates users' daily use.

4. Protocol support: The PD standard is a fast charging protocol whose goal is to achieve efficient, fast and safe charging. Ordinary charging cables usually do not have such protocol support.

5. Charging protocol: PD charging cable adopts the latest USB-C interface and supports the latest USB PD (Power Delivery) protocol, which can achieve fast charging. Ordinary charging cables may only support the traditional USB charging protocol, and the charging speed is relatively slow.

6. Charging power density: The charging power density of the PD charging cable is higher than that of ordinary charging cables, which means that the PD charging cable can provide greater charging power and thus charge faster. Fully charge the device.

7. Heat generation during charging: Because the PD charging cable adopts the latest fast charging technology, it generates relatively little heat during charging, which can reduce safety hazards caused by heat. Ordinary charging cables may generate a lot of heat during charging, so you need to pay attention to heat dissipation issues.

8. Openness of the charging protocol: The PD charging protocol is open, which means that any device that supports the PD protocol can be charged using the PD charging cable. Common charging protocols may be proprietary or only supported by certain brands, limiting their widespread use.

To sum up, there are significant differences between PD charging cables and ordinary charging cables in terms of charging protocol, charging power density, heat generation during charging, and the openness of the charging protocol. These differences give PD charging cables higher advantages in terms of charging efficiency and safety.
