What is PD Charger?

A PD Charger (correctly termed PD Charger, where “PD” stands for Power Delivery) is a type of USB charger that supports the USB Power Delivery (USB-PD) specification. This technology enables faster and more efficient charging for compatible devices by delivering higher power levels compared to standard USB charging

Key Features of a PD Charger

1. High Power Output
   • Supports power delivery up to 100W (or 240W with USB PD 3.1), compared to standard USB chargers (typically 5-15W).
   • Voltage and current can dynamically adjust (e.g., 5V/3A, 9V/3A, 15V/3A, 20V/5A) based on the connected device’s needs.
2. USB-C Compatibility
   • Primarily uses USB-C connectors, which are reversible and support higher power/data transfer.
   • Works with smartphones, tablets, laptops, monitors, and other USB-C devices.
3. Dynamic Voltage Negotiation
   • The charger and device communicate to agree on optimal voltage and current, ensuring safe, fast charging without overheating.
4. Universal Use
   • Charges a wide range of devices (e.g., iPhones, Android phones, MacBooks, Windows laptops, Nintendo Switch, etc.).
   • Replaces proprietary chargers for many laptops (e.g., Apple’s MagSafe).
5. Safety Features
   • Built-in protections against over-voltage, over-current, overheating, and short circuits.
