Power Delivery vs Quick Charge | ZONSAN

2023-01-14 Power Delivery (PD) and Quick Charge (QC) are both fast charging technologies that are used to charge electronic devices quickly. However, there are some key differences between the two.



Power Delivery (PD) is a fast charging technology developed by the USB Implementers Forum (USB-IF). It uses a USB Type-C connector and supports adaptive charging, which automatically adjusts the charging rate to match the device's battery capacity and condition. It can deliver power up to 100W, which allows for faster charging than the standard 5W charging. It also has advanced safety features such as temperature monitoring and protection against overvoltage, overcurrent, and short-circuiting to ensure safe and efficient charging. PD is designed to support a wide range of devices, including laptops, smartphones, tablets, and other portable electronic devices.

Quick Charge (QC) is a fast charging technology developed by Qualcomm. It uses a USB Type-A or USB Type-C connector and supports adaptive charging, which automatically adjusts the charging rate to match the device's battery capacity and condition. It can deliver power up to 18W, which allows for faster charging than the standard 5W charging. QC is compatible with a wide range of devices, including smartphones, tablets, and other portable electronic devices.

In summary, Power Delivery (PD) is a fast charging technology developed by USB-IF that uses a USB Type-C connector, supports adaptive charging and can deliver power up to 100W, it's designed to support a wide range of devices. Quick Charge (QC) is a fast charging technology developed by Qualcomm that uses USB Type-A or USB Type-C connector, supports adaptive charging and can deliver power up to 18W, it's compatible with a wide range of devices.
