Over the years, Apple has been improving the charging capabilities of its iPhone models, aiming to strike a balance between safety and efficiency. While it is possible to produce super-fast chargers, Apple still has to consider temperature control to protect battery life and quality.

Despite the many benefits, the new fast charging technology on the iPhone 17 is not without its drawbacks, especially compatibility. Specifically, to achieve the highest charging speed, users need to use a compatible charger, like the new charger released by Apple. This is a compact charger with retractable plugs, supporting the USB Power Delivery 3.2 standard.

The only fast charging option for iPhone 17 users right now

Apple's charger has a maximum output of up to 60W, called the Apple 40W Dynamic Power Adapter. This is one of the first chargers to use the USB PD 3.2 SPR AVS standard. Although the name may seem complicated, it shows the ability to adjust the power flexibly. SPR (Standard Power Rate) and AVS (Adjustable Voltage Supply) allow the charger to adjust the voltage in 100 mV increments, so the device is charged with the exact amount of power needed.

Thanks to this technology, Apple can charge the iPhone 17 battery to 50% in just 20 minutes without wasting or generating unnecessary heat. Apple's charger is equipped with a single USB-C port. With the support of the open USB Power Delivery standard, other accessory manufacturers will soon launch compatible power supplies. The problem is that users who buy the iPhone 17 at this stage can only choose the 40W charger from Apple to experience the best fast charging feature.
