USB-C Power Delivery (PD) and Qualcomm Quick Charge (QC) are two different fast-charging standards that help a charger and device agree on how much power to send. The biggest difference is who defined the standard and where it’s most commonly used: USB-C PD is a USB-IF standard designed for USB-C devices across many brands, while QC is a Qualcomm technology most associated with many Android phones and certain chargers.
USB-C PD is built into the USB-C ecosystem and is intended to work broadly across phones, tablets, laptops, portable monitors, power banks, and hubs. PD negotiates power over the USB-C connection and can scale from low wattage charging up to higher-power profiles (commonly seen with 45W, 65W, 100W+ laptop charging). Many modern PD chargers also support PPS (Programmable Power Supply), which can fine-tune voltage/current for better efficiency and potentially cooler charging on compatible devices.
Quick Charge is a family of standards (QC 2.0/3.0/4/4+/5) primarily aimed at fast charging for phones. QC became popular on USB-A chargers, though newer QC versions can also run over USB-C and overlap with PD in some implementations. In general, QC focuses on phone-centric fast charging, while PD is the more universal “one charger for many devices” approach—especially when laptops are involved.
If you want maximum compatibility across USB-C gadgets—especially if you charge a laptop—prioritize a quality USB-C PD charger and a properly rated USB-C cable. If your phone specifically advertises Quick Charge and you already own a QC charger, it can still be a good option for fast phone charging, but it may not cover as many device types at higher wattages.
For a deeper breakdown of wattage, cable ratings (like 5A e-marked cables), and how PD 3.0 and QC 4.0 relate, see the full guide here: https://mrsmattie.com/blog/guide-100w-usb-c-to-usb-c-cable-pd-3-0-qc-4-0-5a-explained/.
Sometimes. Many modern chargers support both standards, but compatibility depends on the charger and the device negotiating a shared charging mode.
Apple devices primarily use USB-C Power Delivery for fast charging (for example, iPhones with a USB-C to Lightning cable and many iPads via USB-C). They generally do not rely on Qualcomm Quick Charge.
No. They are different fast-charging standards with different negotiation methods and typical use cases, even though some chargers and phones may support both.
