What Is PD 3.1 and PPS?
2026-01-05 14:33

You buy a brand-new high-power charger, the box says 65W or even 100W, but your phone still takes two or three hours to fully charge.
What went wrong?
The truth is simple but often overlooked:
Fast charging is not only about power. It’s about communication.
Your charger and your device must “speak the same language.”
If they fail to recognize each other’s charging protocols, even the most powerful charger will slow down automatically to protect your device.
In this article, we’ll explain—in plain English—what PD 3.1 and PPS really are, how they unlock full charging speed, and why they matter for both consumers and B2B buyers.
What Is PD 3.1? How Is It Different from PD 3.0?
PD in Simple Terms
PD (Power Delivery) is the most widely used fast-charging standard in the world.
You can think of it as the “common language” of modern charging—used by phones, tablets, laptops, and more.
PD 3.0: The Old Mainstream
For many years, PD 3.0 was the industry standard.
Maximum power: 100W
Perfect for smartphones, tablets, and thin laptops
But increasingly limited when facing:
Gaming laptops
High-performance notebooks
Power-hungry new devices
PD 3.1: The Next Generation
PD 3.1 is a major upgrade—not a minor tweak.
Much more powerful
Maximum output jumps from 100W to 240W
More versatile
Supports not only phones and laptops, but also:
High-performance gaming laptops
E-bikes
Portable power stations
One-sentence summary:
If PD 3.0 is a family car, PD 3.1 is a high-speed train—faster, stronger, and built for the future.
What Is PPS and Why Is It So Important?
PPS Explained in Plain Language
PPS (Programmable Power Supply) is a feature inside the PD standard.
Instead of delivering power in fixed “big steps” (like 5V or 9V), PPS allows the charger to:
Adjust voltage in tiny steps (as small as 0.02V)
Continuously match the phone’s real-time battery needs
Think of PPS as an intelligent fine-tuning controller inside your charger.
Two Key Benefits of PPS
1. Less Heat, Longer Battery Life
Traditional charging jumps between fixed voltages, creating extra heat inside the phone.
PPS uses micro-adjustments to reduce internal power conversion, which means:
Lower temperature
Less battery stress
Slower battery aging over time
2. Unlocks “Hidden” Fast Charging
Many Android flagship phones—especially Samsung’s 45W Super Fast Charging—require PPS.
Without PPS support:
Your phone will charge
But it will fall back to normal speed
In other words, a charger without PPS may look fast, but act slow.
Why Do PD 3.1 and PPS Matter for B2B Wholesalers?
1. Fewer Complaints, Fewer Returns
No more:
“My Samsung doesn’t show Super Fast Charging”
“This charger doesn’t work with my laptop”
Protocol compatibility solves problems before they reach customer service.
2. Simpler Inventory Management
Instead of stocking:
Apple-specific chargers
Samsung-specific chargers
Laptop-only chargers
You can offer one PD 3.1 + PPS charger that works across brands.
3. Future-Proof Product Planning
As iPhone and Android flagships continue increasing charging power,
PD 3.1 chargers are positioned for the next 3–5 years, not just today.
