Apple Unveils World’s First Revolutionary iPhone Charger
▼ Summary
– Apple launched the world’s first charger supporting USB PD 3.2 AVS protocol, called the Apple 40W Dynamic Power Adapter with 60W Max.
– The AVS protocol provides granular voltage options for more precise and efficient charging of smartphones and laptops.
– This technology speeds up charging by delivering a voltage closer to the device’s ideal needs during the charging cycle.
– The charger can only maintain its peak 60W rate for 18 minutes, making it suitable for iPhones but not for power-hungry devices like MacBook Pros.
– Users need Apple’s $39 adapter or a future third-party AVS-compatible charger to achieve Apple’s claimed fast charging speeds for iPhone 17 models.
Apple has quietly introduced what it claims is the world’s first charger supporting the USB PD 3.2 AVS protocol, bundled with its latest iPhone 17 models. Dubbed the Apple 40W Dynamic Power Adapter with 60W Max, this compact unit promises some of the performance benefits of a larger 60W charger while maintaining a smaller 40W footprint.
The key innovation lies in its use of Adjustable Voltage Supply (AVS) technology, which enables the adapter to offer highly granular voltage options. This allows for more precise and efficient power delivery to compatible devices like smartphones and laptops. By matching the ideal voltage required at different stages of the charging cycle, the charger can speed up the process without compromising safety or battery health.
Batteries in modern electronics don’t charge at their peak input rate throughout the entire cycle. Instead, charging slows down as the battery fills to preserve longevity. With AVS, the power source can dynamically adjust voltage to stay closer to the optimal level, reducing energy waste and shortening charge times.
It’s important to note, however, that this adapter isn’t a full 60W unit. Testing by users on platforms like Reddit’s r/UsbCHardware community shows it can only sustain its peak 60W output for around 18 minutes. That makes it well-suited for quickly topping up an iPhone 17, but not for powering a MacBook Pro under heavy load. Hence, Apple markets it as a 40W charger “with 60W Max” rather than a true 60W model.
For now, achieving Apple’s advertised fast-charging claim, up to 50 percent battery in just 20 minutes with the iPhone 17, requires this specific $39 adapter. Third-party alternatives from brands like Anker may eventually support the USB PD 3.2 AVS standard, but for the moment, Apple’s offering stands alone.
