PPS vs AVS: What's the Difference and Which Fast Charging Technology Is Better? If Your Charger Supports PPS, Do You Still Need AVS? If you've been shopping for a new USB-C charger recently, you've probably noticed product descriptions mentioning terms like PPS, AVS, PD 3.1, or PD 3.2.
To many consumers, they all sound like different versions of the same thing.
In reality, they serve different purposes.
PPS and AVS are both intelligent voltage regulation technologies within the USB Power Delivery ecosystem, but they were designed for different generations of devices and different power requirements.
Understanding the difference can help you choose the right charger—especially if you're buying a charger for a flagship smartphone, a gaming laptop, or an AI PC.
What Is PPS? PPS stands for Programmable Power Supply.
It was introduced as part of USB Power Delivery 3.0 to improve charging efficiency for mobile devices.
Instead of supplying only fixed voltages such as:
• 5V / 9V / 15V / 20V
PPS allows the charger to adjust voltage in very small increments based on what the device requests.
This dynamic adjustment helps reduce heat while improving charging efficiency.
For smartphones, that's a significant advantage because lithium-ion batteries charge more efficiently when voltage can be fine-tuned. Related Reading: PD3.0 vs PD3.1 vs PD3.2 (AVS). ↗
Why PPS Became Popular Many Android manufacturers adopted PPS because it enabled:
• Faster charging
• Lower charging temperatures
• Better battery protection
• Improved charging efficiency
Today, PPS is widely supported by flagship smartphones, tablets, and many USB-C power banks.
What Is AVS? AVS stands for Adjustable Voltage Supply.
It was introduced with USB PD 3.1 as part of the Extended Power Range (EPR) specification.
Unlike PPS, AVS is designed to support much higher voltage levels required by larger devices.
Typical AVS voltage ranges include:
• Up to 28V
• Up to 36V
• Up to 48V
This makes AVS suitable for devices that require much more power than smartphones. Related Reading: What Is USB-C EPR? ↗

The key difference isn't which technology is "better."
It's what type of device you're charging.
Why AVS Matters for High-Power Devices Modern laptops demand far more power than smartphones.
For example:
• Gaming laptops
• Mobile workstations
• AI-enabled notebooks
• Professional monitors
These devices often require more than 100W.
AVS allows chargers to adjust voltage over a much wider range while maintaining safe and efficient power delivery.
Does AVS Charge Faster Than PPS? Not necessarily.
Charging speed depends on several factors:
• Device design
• Battery management system
• Charger output
• Cable capability
• Thermal conditions
A smartphone that supports PPS won't charge faster simply because it's connected to an AVS charger.
Likewise, a gaming laptop won't benefit from PPS if it requires AVS and EPR.
Can One Charger Support Both PPS and AVS? Yes.
Many modern premium GaN chargers support multiple protocols simultaneously, including:
• USB PD 3.0
• USB PD 3.1
• PPS
• AVS
• QC 4+
• QC 5
This ensures broad compatibility across smartphones, tablets, laptops, and future USB-C devices.
Which Devices Use PPS? PPS is commonly found in:
• Android flagship phones
• Tablets
• USB-C power banks
• Some portable gaming consoles
For these devices, PPS delivers excellent charging efficiency and helps reduce battery heat.
Which Devices Benefit from AVS? AVS is designed for higher-power equipment, including:
• Gaming laptops
• AI PCs
• Professional laptops
• USB-C docking stations
• High-resolution monitors
• Future 140W–240W USB-C devices
The Future of USB Power Delivery USB-C charging continues to evolve toward:
• Higher power
• Better efficiency
• Smarter voltage regulation
• Universal compatibility
Rather than replacing PPS, AVS expands the USB Power Delivery ecosystem to support an even wider range of devices.
In the future, it's likely that premium USB-C chargers will support both technologies by default.
Final Thoughts PPS and AVS are not competing technologies.
They solve different challenges.
• PPS improves charging efficiency for smartphones and tablets.
• AVS extends intelligent voltage regulation to high-power devices using USB PD 3.1 and EPR.
As USB-C becomes the universal charging standard, understanding both technologies will help consumers choose chargers that are compatible with today's devices—and tomorrow's.
FAQ Q1: What is PPS charging?
PPS (Programmable Power Supply) is a USB PD 3.0 technology that dynamically adjusts voltage to improve charging efficiency and reduce heat, especially for smartphones and tablets.
Q2: What is AVS charging?
AVS (Adjustable Voltage Supply) is part of USB PD 3.1 EPR and enables intelligent voltage adjustment at higher voltage levels, supporting up to 240W charging for laptops and other high-power devices.
Q3: Is AVS better than PPS?
Neither is universally better. PPS is optimized for mobile devices, while AVS is designed for high-power devices such as gaming laptops, AI PCs, and monitors.
Q4: Does AVS replace PPS?
No. AVS complements PPS rather than replacing it. Many modern USB-C chargers support both technologies.
Q5: Can one charger support both PPS and AVS?
Yes. Many high-quality GaN chargers support USB PD 3.1, PPS, AVS, and other fast charging protocols, allowing them to charge a wide range of devices.
Q6: Do iPhones use PPS or AVS?
Current iPhones primarily use USB Power Delivery (PD) and do not require PPS or AVS for fast charging. PPS is more commonly used by Android devices, while AVS targets higher-power USB-C equipment.
Q7: Do I need AVS for a gaming laptop?
If your gaming laptop supports USB PD 3.1 or requires charging above 100W, an AVS-compatible charger and an EPR USB-C cable are recommended to achieve optimal charging performance.
Q8: Will AVS become more common?
Yes. As more laptops, monitors, AI PCs, and USB-C accessories adopt USB PD 3.1 and 240W charging, AVS is expected to become a standard feature in premium USB-C chargers.
