Apple has introduced a new compact charger called the 40W Dynamic Power Adapter, designed specifically for users who want powerful charging in a very small form factor. This new adapter represents a significant step in charging technology, though it comes with a notable tradeoff related to its power delivery.
The key innovation is its support for the USB PD 3.2 AVS protocol, which stands for Adjustable Voltage Supply. This allows the charger to dynamically adjust its power output to match the specific needs of a device at different stages of its charging cycle. While its base rating is 40W, it can temporarily boost its output to a maximum of 60W for short bursts. According to user testing, this peak power of 60W is available for a limited time, approximately 18 minutes, making it ideal for a quick battery top-up.
This dynamic power capability is engineered to work with Apple’s latest iPhone 17 models, enabling significantly faster charging speeds. Apple states that when paired with an iPhone 17, the charger can reach a 50 percent battery level in roughly 20 minutes. It also works with the iPhone Air, achieving a 50 percent charge in about 30 minutes.
The primary advantage of this charger is its physical size. It is remarkably small for its power capabilities, with a footprint not much larger than the most compact 40W chargers currently available. It features fold-down prongs, making it extremely portable and easy to slip into a pocket without adding noticeable weight or bulk. This addresses a common pain point for travelers and professionals who dislike carrying heavy, large power bricks. For comparison, popular third-party options like Anker’s Nano II 65W GaN charger are about twice the physical size of Apple’s new model.
However, there are limitations to consider. The temporary nature of the 60W boost means this charger is not suitable for consistently powering energy-hungry devices like laptops, which require a sustained high wattage. It is optimized for smartphones and similar small devices. The other significant consideration is the price. At forty dollars, the Apple 40W Dynamic Power Adapter is almost twice the cost of many capable third-party alternatives, including the aforementioned Anker 65W model.
In summary, Apple’s new charger offers a compelling solution for iPhone users who prioritize portability and ultra-fast charging speeds for their phone. Its intelligent, dynamic power delivery and incredibly small size are its main selling points, but buyers must accept that it is designed for specific Apple devices and comes at a premium price compared to the broader charger market.
