Apple has recently launched a revolutionary charging accessory alongside the iPhone 17 series - the "Apple 40W Dynamic Power Adapter with 60W Max", becoming the world's first charger to support the USB PD 3.2 AVS protocol. This compact 40W charger delivers advantages comparable to some 60W chargers through its innovative adjustable voltage technology, though it's not yet available on Apple's official Hong Kong website.
Technical Breakthrough Enables More Precise Charging Experience
The charger's most notable feature is its adoption of AVS (Adjustable Voltage Supply) technology, which provides a more precise voltage regulation range. Unlike traditional chargers with fixed voltage stages, AVS technology enables more granular voltage output adjustments, allowing devices to control charging power more precisely when the battery is nearly full.
This technology makes the charging process for smartphones and laptops safer and more efficient. When the battery approaches full charge, the charger gradually reduces charging speed, and AVS technology allows the power supply to provide voltage that perfectly matches the device's needs, thereby improving charging efficiency and extending battery lifespan.
Essential Accessory for iPhone 17 Fast Charging
For iPhone 17 Pro and Pro Max users, this charger is not just an optional accessory but a necessity to unlock the phone's fast charging capabilities. Apple claims that the new iPhone 17 can charge up to 50% in just 20 minutes, but users must use an AVS protocol-compatible charger to achieve this performance.
Key Features of AVS Technology
- More precise voltage regulation for optimal charging efficiency
- Enhanced battery health through tailored power delivery
- Support for a wide range of devices up to 100W power delivery
Market Leadership and Pricing Considerations
Currently, Apple's charger is the only product on the market that supports the USB PD 3.2 SPR AVS specification, giving the company a leading edge in this emerging technology field. Priced at $39 in the US, users also have the option to wait for compatible USB PD 3.2 AVS chargers from other brands like Anker.
