USB PD 3.0 Charger is a fast charging technology that was developed by the USB Implementers Forum. Because it’s an official part of USB technology, it can be supported by any manufacturer

In addition to 100-watt power, there are four other wattage levels: 7.5, 15, 27, and 45 watts are all supported. This makes the PD standard exceptionally versatile. Manufacturers can build a wide variety of devices, and still, get top-tier performance

• Provide more power
• Process data more efficiently
• Identify devices faster

The difference between the two types of PD charging lies in the amount of detailed information given by each. This includes reporting any malfunction or system change within the device, the temperature of the device, or what may be causing hold-ups or decreased charging speed, etc

Sources say that it's best to use USB PD 2.0 for simple devices that don't necessarily need extra or in-depth information presented. One should use USB PD 3.0 if the new features are required in your device's application
