AVS vs. PD vs. PPS: What Charger Buyers Need to Know
AVS (Adjustable Voltage Supply) is a new feature introduced in USB Power Delivery 3.2.
• It allows fine voltage adjustments in 100mV steps.
• Instead of using fixed steps (5V, 9V, 15V, 20V), AVS lets the charger provide more precise voltage output.
• The result: higher efficiency, less heat, safer charging.
Apple’s iPhone 17 40W charger is the first major product to use AVS protocol, delivering up to 60W peak output with stable voltage control.
👉 AVS is becoming the new standard for high-power USB-C fast charging.
🤔 2. Is AVS a Private Charging Protocol?
Unlike proprietary fast charging protocols from smartphone brands (such as Xiaomi HyperCharge, Huawei SuperCharge, OPPO VOOC, OnePlus Warp Charge, Samsung Super Fast Charge), AVS is not private.
• AVS is part of the official USB-IF standard under PD 3.2.
• Proprietary protocols (like VOOC or Warp) require brand-specific chargers and cables.
• AVS works with any compatible charger and device, provided both support USB PD 3.2 AVS.
So, while Huawei 66W charger or Xiaomi 120W HyperCharge are limited to brand ecosystems, AVS chargers will be cross-brand compatible in the future.

⚡ 3. AVS vs. PD vs. PPS
| Protocol | Full Name | Introduced | How It Works | Devices Supported |
| PD | Power Delivery | USB-IF, PD 2.0/3.0 | Fixed voltage steps (5V/9V/15V/20V) | Laptops, smartphones, tablets |
| PPS | Programmable Power Supply | PD 3.0 | Adjusts voltage & current dynamically in real-time | Samsung Galaxy S/Note, some Androids |
| AVS | Adjustable Voltage Supply | PD 3.2 | 100mV fine voltage steps, higher efficiency | iPhone 17, future Apple/USB-C devices |
👉 In short:
·PD = the foundation.
·PPS = dynamic adjustments (great for Android).
·AVS = finer precision, better efficiency (pushed by Apple).
🏭 4. What Should Charger Manufacturers & B2B Buyers Do About AVS?
For Charger Manufacturers (OEM/ODM Factories):
• Adopt AVS in GaN chargers (45W–140W) to stay compatible with iPhone 17 and future Apple devices.
• Add multi-protocol support (PD, PPS, AVS) to cover both iOS and Android markets.
• Highlight certifications (CE, RoHS, KC, FCC) to reassure distributors and retailers.
For B2B Buyers (Brands, E-commerce, Wholesalers):
• PD/PPS — many Android brands still rely on PPS.
• Invest in AVS-compatible chargers to prepare for Apple’s dominance in premium markets.
• Offer hybrid SKUs: e.g. 65W GaN AVS+PPS charger, ensuring wide compatibility across devices.
• Watch for 100W 140W 240W GaN multi-port chargers — the future of laptops + phones fast charging hubs.
👉 Bottom line: AVS isn’t a replacement for PD/PPS yet, but a strong complement.
✅ 5. Conclusion
AVS is not a proprietary protocol but an official extension of USB PD 3.2, starting with Apple’s iPhone 17 charger.
• PD remains the global standard.
• PPS dominates Android fast charging.
• AVS is Apple’s path forward and will likely expand in future laptops, iPads, and third-party chargers.
For factories, OEMs, and wholesalers, the winning strategy is clear: produce AVS+PD+PPS multi-protocol GaN chargers (from 20W to 240W) to serve both Android and iOS markets.
FAQ: AVS vs. PD vs. PPS
Q1: Is AVS the same as PD?
A1: No. PD (Power Delivery) is the broader standard, while AVS (Adjustable Voltage Supply) is a new feature in PD 3.2, offering finer voltage control for safer, more efficient fast charging.
Q2: Does AVS replace PPS?
A2: Not exactly. PPS (Programmable Power Supply) adjusts voltage/current dynamically, mainly used in Android fast charging (e.g., Samsung). AVS focuses on precision voltage steps (100mV) and is being pushed by Apple. They will co-exist.
Q3: Can I use a PD charger with iPhone 17?
A3: Yes, any USB-C PD charger will work with iPhone 17. However, only PD 3.2 AVS chargers (like Apple’s new 40W adapter) will unlock the full fast charging performance.
Q4: Are AVS chargers cross-brand compatible?
A4: Yes. Unlike proprietary fast charging (Huawei SuperCharge, Xiaomi HyperCharge, OPPO VOOC), AVS is part of the USB-IF standard, so future Android and Apple devices may both support it.
Q5: What should OEM charger manufacturers focus on?
A5: Charger factories should design GaN chargers with multi-protocol support (PD + PPS + AVS). This ensures compatibility across iPhone, Samsung, Huawei, Xiaomi, and laptops — boosting B2B sales and wholesale orders.
