What is PD / QC Charging?

[ahr43]

Been wanting to upgrade my AA/AAA NiMH charger. Got this SkyRC product release Email.

NC3000 Pro

It requires a Power Delivery (PD), Quick Charge (QC) external supply. Is this like a cell phone charger, or a lead that feeds off a 5v/2.1A USB port? -AC

It's a high power wall charger.

Thanks, Kevin. Did a SkyRC search on Amain and found this. A suitable power supply? Also would it work as a power supply for the iSDT charger on my wish list? -AC

SkyRC PCH-158W

Yeah, that would be plenty powerful for the ISDT

Notice that first port says 18w. That's what the ISDT uses

Power Delivery (PD) vs. Quick Charge (QC) – Key Differences​

Both Power Delivery (PD) and Quick Charge (QC) are fast-charging technologies, but they differ in compatibility, speed, and power output.

---

USB Power Delivery (PD)​

• Developed by: USB-IF (USB Implementers Forum)
• Compatibility: Works with USB-C devices, including phones, tablets, laptops, and accessories.
• Power Output: Supports up to 240W (depending on the version).
• Voltage Levels: 5V, 9V, 12V, 15V, 20V (adjustable up to 48V in PD 3.1).
• Intelligent Power Negotiation: Adjusts power based on the device’s needs.
• Common Devices: iPhones (since iPhone 8), Android phones, MacBooks, iPads, Nintendo Switch.

Best for: Universal charging (phones, laptops, tablets, gaming consoles).

Qualcomm Quick Charge (QC)​

• Developed by: Qualcomm
• Compatibility: Works mainly with Qualcomm Snapdragon-based Android phones.
• Power Output: Up to 100W (QC 5).
• Voltage Levels: 5V, 9V, 12V, 20V (some versions allow dynamic scaling).
• Backward Compatibility: Older versions (QC 2.0, 3.0) still work with newer devices.
• Common Devices: Samsung Galaxy, Xiaomi, OnePlus, Motorola, some gaming laptops.

Best for: Fast-charging Snapdragon-powered Android devices.

Which One is Better?​

• If you need universal compatibility: USB-PD is better (works with laptops, iPhones, and more).
• If you have a Qualcomm Snapdragon phone: QC may charge faster for your device.
• If you want the highest power output: PD 3.1 (up to 240W) beats QC 5 (100W max).
