As reported by The Verge.
Together with the iPhone 17 lineup, Apple introduced not only smartphones but also a new charger that became a world first: a 40-watt dynamic power adapter with a peak power of up to 60 W. The compact body allows convenient use via USB‑C and charging various gadgets at home or on the go.
The adapter supports the USB PD 3.2 AVS protocol, where AVS stands for Adjustable Voltage Supply – adjustable voltage delivery. This enables the power source to deliver more precise voltage levels and charge smartphones and laptops more efficiently.
Thanks to AVS, charging becomes faster and more convenient: the device delivers voltage closer to the battery’s needs, saving charging time and reducing heat.
However, it’s important to understand that this is not a fully 60-watt adapter. The GaN adapter from Apple cannot sustain a 60 W peak continuously – roughly 18 minutes according to tests in the r/UsbCHardware community. This format is suitable for fast charging the iPhone 17, but not intended for prolonged operation of a MacBook Pro at maximum load.
If you need a full 60 W fast charging implementation for the iPhone 17 and larger devices, perhaps you should consider Apple’s official Dynamic Power Adapter for $39 or await compatible solutions from other manufacturers, such as Anker, which also integrate USB PD 3.2 AVS.
Impact on daily use
The new 40-watt adapter with AVS offers a convenient solution for daily use with the iPhone 17 and other devices, allowing you to quickly top up the battery. However, for laptops or users who require a stable peak load, consider options that actually deliver a full 60 W.
In summary, the compact adapter’s convenience and fast charging are its main advantages, while the wish to obtain maximum 60 W of power for sustained use is better realized through other solutions with full capability.
