What Is A PD Charger And How to Choose A PD Charger |ZONSAN
What Is a PD Charger?
PD stands for “Power Delivery”, a fast-charging technology using USB-C to supply higher power levels across a wide range of devices—phones, tablets, laptops, and more. In 2025, PD chargers remain a cornerstone for universal fast charging.
PD Protocol Versions – Updated to 2025
PD 1.0: Introduced around 2012, basic power delivery via USB.
PD 2.0: Around 2014, added higher wattages and wider device support.
PD 3.0: From ~2017, introduced PPS (Programmable Power Supply) for dynamic voltage/current.
PD 3.1: Released ~2021, supports up to 240W and high-power applications.
PD 3.2: Released ~2025.9, introduces protocols such as AVS (Adjustable Voltage Supply) (Apple launched a 45W AVS original Apple charger at the iPhone 17 launch event) and DPS (Direct Power Supply) for improved precision and compatibility.
Each new version is backward-compatible—so a PD 3.1 or 3.2 charger works with earlier devices.
How to Choose a PD Charger in 2025
When selecting a PD charger, consider the following factors:
1. Compatibility – Ensure the charger supports the required wattage for your device (phones vs laptops).
2. Output Power – Measured in Watts (W). For example: 20W, 25W, up to 100W or 240W.
3. Size & Portability – Compact chargers (GaN technology) are ideal for travel and everyday carry.
4. Brand & Price – Choose a reputable PD charger factory or OEM supplier for long-term reliability.
5. Additional Features – Multiple ports, smart chip technology, universal compatibility (PD + PPS + AVS).
6. Certifications – CE, RoHS, UL, KC, UKCA etc. are essential for global markets.
7. Future-proofing – With protocols like AVS and DPS emerging, a charger supporting PD 3.2 is more future-ready.
Modern Protocols & Compatibility
Today’s PD chargers often support multiple protocols:
• PD (USB-IF standard)
• PPS (used widely by Android brands)
• AVS (emerging for precision voltage control)
• DPS (high-power direct delivery)
A well-designed charger from a reliable factory will support these protocols, making it compatible with iPhone, Samsung, laptops, tablets and more.
FAQ
Q: Can a 20W PD charger fast-charge a laptop?A: Only basic laptops or tablets. For full laptop performance, 65W–100W or higher is recommended.
Q: Do I need a special cable for a PD charger?
A: Yes. Use a USB-C cable rated for the required wattage, ideally with E-mark for high-wattage.
Q: Will a PD charger work with older USB-A devices?
A: Yes via USB-C to USB-A cables/adapters, but you lose PD benefits; charging speed will be lower.
Q: Is PD better than proprietary fast-charging like VOOC or Warp?
A: PD offers broad compatibility across brands and devices; proprietary protocols may charge faster for that brand but lack universality.
In 2025, choosing a PD charger means thinking compatibility, power, and future readiness.
