What is the difference between PD fast charging and general fast charging?

The differences between pd fast charging and general fast charging include charging speed, charging protocol, compatibility, multi-function and safety. Detailed introduction: 1. Charging speed. Compared with general fast charging technology, PD fast charging technology has faster charging speed. PD fast charging technology supports high power output, up to 100W, while general fast charging technology usually ranges from 18W to 30W. Between; 2. Charging protocol, PD fast charging technology is an open standard charging protocol that can adapt to different devices and power supplies. It can dynamically adjust the output power according to the needs of the charging device to achieve the best charging effect, etc. .

PD fast charging (Power Delivery) and general fast charging are two common methods in modern mobile device charging technology. While they both offer fast charging capabilities, there are clear differences in some key aspects. Below I will introduce the differences between these two fast charging technologies in detail.

Charging speed:

PD fast charging technology has faster charging speed than general fast charging technology. PD fast charging technology supports high power output, up to 100W, while general fast charging technology is usually between 18W and 30W. This means that using PD fast charging technology can transfer power to mobile devices faster, thus providing faster charging speeds.

Charging protocol:

PD fast charging technology is an open standard charging protocol that can adapt to different devices and power sources. It can dynamically adjust the output power according to the needs of the charging device to achieve the best charging effect. Generally, fast charging technology is usually a proprietary protocol developed by a specific device manufacturer and can only be used between the corresponding device and the charger.

Compatibility:

PD fast charging technology is more compatible in the market. Since it is an open standard charging protocol, more and more device manufacturers are beginning to support PD fast charging technology. Generally, fast charging technology is usually only suitable for specific brands or models of devices, and may not be available for other devices.

Multi-function:

PD fast charging technology can not only provide fast charging for mobile devices, but also charge a variety of devices through a single charging cable. For example, charging cables using PD fast charging technology can charge laptops, tablets, smartphones and other devices at the same time. Generally, fast charging technology is usually only suitable for specific devices and cannot provide charging for other types of devices.

Safety:

PD fast charging technology has higher safety during the charging process. Because PD fast charging technology uses more advanced communication protocols and energy management mechanisms, parameters such as current and voltage can be monitored and managed in real time, thereby better protecting equipment from problems such as overcurrent and overheating. Generally, fast charging technology may have some safety hazards during the charging process due to its lower power output.

To sum up, there is a clear difference between PD fast charging and general fast charging. PD fast charging technology has the advantages of faster charging speed, stronger compatibility, more functions and higher safety. However, general fast charging technology also has its applicable scenarios, especially for certain brands or models of devices. As a programmer, understanding these differences can help us make better decisions when developing software or hardware related to mobile device charging and provide users with a better charging experience.
