Alongside the iPhone 17 launch, Apple quietly introduced a new charging accessory that could reshape how we think about powering our devices. The Apple 40W Dynamic Power Adapter with 60W Max is the first charger in the world to support the USB PD 3.2 AVS (Adjustable Voltage Supply) protocol, a major step forward in efficient, safe, and faster charging.
What Makes AVS Special?
Traditional chargers deliver power at predefined voltage levels, which means devices often receive less-than-optimal charging efficiency. The AVS technology in Apple’s new adapter changes that by offering more granular voltage control. This allows the charger to deliver exactly the right amount of power that a device needs at any given time, reducing heat buildup and increasing battery health over time.
For users, this translates into faster charging speeds without overheating, particularly beneficial for iPhones and other portable devices.
40W Charger with 60W Boost
Despite being marketed as a 40W charger, the new adapter can deliver up to 60W of power — though only for short bursts of about 18 minutes, according to real-world tests shared on the r/UsbCHardware subreddit. This is enough to support Apple’s official claim of charging the iPhone 17 to 50% in just 20 minutes, but not enough to fully power larger devices like a MacBook Pro over sustained use.
That explains Apple’s careful branding: it is a 40W charger “with 60W Max,” rather than a true 60W replacement.
Why It Matters for iPhone 17 Users
For iPhone 17 owners looking to unlock the fastest charging speeds promised by Apple, this new charger is almost a necessity. While third-party brands like Anker may eventually release compatible USB PD 3.2 AVS chargers, Apple’s $39 Dynamic Power Adapter is currently the only option designed to fully support the iPhone 17’s new charging standard.
Apple’s move signals a wider industry shift. As more device makers adopt USB PD 3.2 AVS, we could see a new generation of smarter, more efficient chargers that adapt to the exact needs of every gadget, from phones to laptops.
For now, the Apple 40W Dynamic Power Adapter stands as both a world first and a glimpse into the future of mobile power — one where charging is faster, safer, and more efficient than ever before.
