According to Kuaitech on September 13th， Apple has significantly boosted charging power with the iPhone 17 series officially supporting 40W fast charging.
Interestingly， Apple appears to have implemented a strategy of “under-promising and over-delivering” with the actual peak charging power reaching up to 60W. This approach deviates from previous charging capabilities and sets a new benchmark for iPhone charging speeds.
ChargingHead.com reports that the iPhone 17 series is the first to adopt charge pump technology. This technology is known for enhancing charging efficiency and reducing heat generation， a welcome improvement for users.
Apple has also released a 40W dynamic power adapter with a price tag of 329 yuan. This new adapter signifies Apple’s commitment to providing higher power solutions for its devices.
This charging head supports the AVS fast charging protocol， which can be viewed as an upgraded version of PPS. While it can achieve overclocked power of up to 60W， this performance is conditional on the device and charger successfully negotiating the AVS protocol handshake.
The specific specifications are as follows:
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. The maximum total output power is 60W (only applicable at altitudes of 5000 meters and below).
Apple officially claims that this charger can charge various iPhone 17 models up to 50% in about 20 minutes， and the iPhone Air up to 50% in approximately 30 minutes. These figures represent a significant improvement， potentially reducing user waiting times for crucial power top-ups.
However， following Apple’s historical practices， the actual real-world charging experience， including sustained peak power output duration， remains a point of speculation. Actual performance figures will likely only be confirmed after thorough hands-on testing following the device’s release.
