Introduction
On September 10, 2025, Apple held its 2025 Fall New Product Launch event, unveiling the iPhone 17 series along with a series of major new products.
At the same time, Apple launched a 40W dynamic power adapter on its official website, which supports fast charging and is fully compatible. Its peak power can reach 60W, dynamically adjusting the output power according to the device’s needs to enhance charging speed.
Online leaks have already disclosed the parameters of this adapter, showing that it can achieve 40W wired fast charging through AVS technology.
The specific parameters obtained from the CQC China Quality Certification Center are as follows:
Model: A3365
Input: 100-240V~, 50-60Hz, 1.5A (USB PD)
Output:
(AVS) 15.0-20.0Vdc, 2.0A [3.0A DPS]
or (AVS) 9.0-15.0Vdc, 2.67A [3.0A DPS]
or 9.0Vdc, 3.0A
or 5.0Vdc, 3.0A
Maximum total output power 60W
(Only applicable below 5000 meters altitude)
Apple claims that with this charger, the iPhone 17 series models can charge up to 50% in about 20 minutes. This suggests that the new iPhone continues to support fixed voltage levels of USB-PD and has likely added compatibility for AVS.
AVS is a new adjustable voltage feature added to USB-PD since the PD3.1 standard, previously mainly used in high voltage/high power scenarios (EPR), specifically for power levels of 140W and above.
However, since the update of the PD3.2 standard in October 2024, the AVS mechanism has also been extended to the SPR standard power range (27W–100W), allowing devices to precisely match various terminal charging needs with a minimum step of 100mV between 9V and 20V, effectively improving energy conversion efficiency and reducing heat loss.
Charging Head Network has previously compiled a history of the development of USB-PD charging standards, which can provide a better understanding.
Next, Charging Head Network will recommend several AVS-supported protocol chips available on the market. Using these AVS-supported chips will allow chargers to accurately adjust output voltage and power according to the real-time needs of terminals such as the iPhone 17 series, thereby improving charging efficiency, reducing heat, and enhancing the charging experience.

Next, Charging Head Network will provide detailed introductions of these AVS-supported protocol chips.

This technology announces the adjustable voltage range at the source end and initiates precise voltage requests as needed at the sink end, allowing the charger to supply power at a voltage closer to the system’s optimal point, thereby reducing conversion losses and improving heat and efficiency, which is one of the underlying supports for Apple’s emphasis on a faster wired charging experience.
The release of this charger and the compatibility of the iPhone 17 series with AVS will undoubtedly drive the industry chain. In the past, many compact chargers positioned in the 20–45W range relied more on fixed PDO or PPS in their solution selection, and protocol chips and reference designs did not universally consider AVS as a default feature. The compatibility of the iPhone 17 series with AVS also means that future protocol chips, control firmware, and testing items will have to upgrade to support AVS, prompting chip manufacturers, OEMs, and the supply chain to reassess their solutions and cost structures.
