Understanding QC and PD: The Core Protocols of Fast Charging

To choose the right QC/PD car charger, you first need to understand what each protocol does, their differences, and how they work together to power your devices.

What is QC (Quick Charge)?

Developed by Qualcomm, Quick Charge (QC) is a proprietary fast-charging protocol designed primarily for devices with Qualcomm Snapdragon processors. It revolutionized fast charging by dynamically adjusting voltage and current to deliver power efficiently.

Key Specifications: Early versions (QC 2.0) topped out at 18W, but modern iterations like QC 4.0+ and QC 5.0 support up to 100W+ power output. QC 3.0 remains widely used, offering 38% higher efficiency than QC 2.0.
Working Principle: It uses a high-voltage, low-current approach (e.g., 9V/2A or 12V/1.5A) and adjusts voltage in stages based on the device’s charging needs.
Compatibility: Ideal for mid-range to high-end Android devices, including Samsung, Xiaomi, and Google Pixel models with Snapdragon chips. Most QC car chargers are backward-compatible with older QC versions and non-QC devices (charging at standard speeds).

What is PD (Power Delivery)?

USB Power Delivery (PD) is an open standard developed by the USB Implementers Forum (USB-IF), making it a universal protocol for modern electronics. It’s designed to handle higher power outputs and broader device compatibility.

Key Specifications: PD 3.0 supports up to 100W, while the latest PD 3.1 extends this to 240W, making it suitable for laptops and high-power devices. It operates on a 3V-48V wide voltage range and up to 5A current.
Working Principle: Uses real-time negotiation via the CC communication pin to dynamically match voltage and current to the device, reducing energy loss. It requires E-Marker certified cables to ensure safe power transmission.
Compatibility: The go-to protocol for iPhones, iPads, USB-C laptops (MacBooks, Dell XPS), and most premium Android devices. It’s also mandated by the EU for future electronic devices, solidifying its status as an industry standard.
