QC30 fast charging and PD fast charging are two different fast charging technologies, which differ in usage scenarios, charging speeds, and charging devices.
Usage Scenario:
QC30 fast charging is commonly used for devices such as Android phones and tablets, while PD fast charging is mainly used for Apple series devices such as iPhones and iPads.
Charging speed:
The maximum output power of QC30 fast charging can reach 18W, supporting a charging speed three times faster than a conventional charger, but its speed is slightly slower than that of PD fast charging. The maximum output power of PD fast charging can reach 100W, which can quickly charge Apple devices in a short time, and its speed is faster than that of QC30 fast charging.
Charging device:
QC30 fast charging is a technology developed by Qualcomm, so only devices that support QC fast charging can enjoy the advantages of QC30 fast charging. While PD fast charging is a technology launched by the USB-IF (USB Implementers Forum) standardization organization. As long as the device supports the USB PD protocol, it can use PD fast charging.
Overall, both QC30 and PD fast charging are technologies introduced to quickly charge smart devices. However, they differ in terms of usage scenarios, charging speeds, and charging devices. Users need to choose the appropriate fast charging technology based on their own devices and usage needs.
