Apple provides powerful assistants for the iPhone 17.

Apple has drawn attention with its new fast charging technology on the iPhone 17, allowing users to charge 50% of the battery in just 20 minutes.

However, few people know that to take full advantage of the fast charging technology on the iPhone 17, users need to own the new charger from the company, which sells for $39.

Over the years, Apple has continuously improved the charging capabilities of its iPhone models, aiming for a balance between safety and efficiency. While it is perfectly capable of producing super-fast chargers, Apple still needs to consider temperature control to protect battery lifespan and quality.

Despite its many benefits, the new fast charging technology on the iPhone 17 also has drawbacks, particularly regarding compatibility. Specifically, to achieve the highest charging speed, users need to use a compatible charger, like the new charger released by Apple. This charger has a compact design with retractable prongs and supports the USB Power Delivery 3.2 standard.

The only fast charging option available to iPhone 17 users right now.

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

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