What’s the Difference Between Type-C PD and Quick Charge?

With fast charging becoming standard in smartphones, laptops, and consumer electronics, two technologies are often mentioned: Type-C Power Delivery (PD) and Quick Charge (QC).
Although both aim to deliver faster and more efficient charging, they are quite different in terms of standards, compatibility, and application scenarios.

So, what’s the real difference between Type-C PD and Quick Charge, and which one is better for your device?

What Is Type-C Power Delivery (PD)?

Type-C Power Delivery, commonly known as USB-C PD, is a universal fast-charging standard defined by the USB-IF (USB Implementers Forum). It uses the USB Type-C connector and supports intelligent power negotiation between the charger and the device.

Key features of USB-C PD include:

• Power output up to 240W (PD 3.1)

• Bi-directional power flow

• Dynamic voltage and current adjustment

• Wide compatibility across multiple devices

Type-C PD is widely used in:

• PD chargers and wall chargers

• Laptop power adapters

• Smartphones, tablets, and monitors

• Docking stations and consumer electronics

Because of its versatility, PD has become the mainstream solution for modern switching power supplies.

What Is Quick Charge (QC)?

Quick Charge is a fast-charging technology developed by Qualcomm, mainly designed for devices using Qualcomm chipsets.

Main characteristics of Quick Charge:

• Typically uses USB-A to USB-C or USB-A cables

• Fixed or stepped voltage levels (5V / 9V / 12V / 20V)

• Common versions include QC 2.0, QC 3.0, QC 4.0

• Optimized for Android smartphones

Quick Charge technology is still commonly found in:

• Smartphone chargers

• Power adapters for legacy devices

• Cost-sensitive consumer electronics

Key Differences Between Type-C PD and Quick Charge

1. Standardization

• Type-C PD: An open, global USB standard

• Quick Charge: A proprietary technology by Qualcomm

PD is supported by more brands and platforms, including Apple, Google, Microsoft, and major laptop manufacturers.

2. Power Capability

• USB-C PD: Supports higher power levels, ideal for laptops, monitors, and high-power adapters

• Quick Charge: Primarily designed for smartphones and low-to-mid power devices

For applications above 30W–45W, PD power adapters are generally preferred.

3. Compatibility

• PD chargers work with a wide range of devices using a single Type-C port

• QC chargers require device-side QC support

PD offers better cross-platform compatibility, reducing the need for multiple chargers.

4. Cable and Connector

• Type-C PD requires a USB-C connector on both ends

• Quick Charge often uses USB-A ports

As USB-C becomes the industry standard, PD is more future-proof.

Which One Should You Choose?

• For laptops, tablets, and multi-device charging, Type-C PD chargers are the better choice

• For older smartphones or legacy systems, Quick Charge can still be effective

• For manufacturers and brands, PD power solutions offer better scalability and long-term value

As the industry moves toward USB-C standardization, Type-C PD is clearly becoming the dominant fast-charging technology.
