Apple’s 40W Dynamic Power Adapter can briefly deliver up to 60W using advanced PD 3.2 and AVS technology, then automatically reduces output to 40W to manage heat and ensure safety. This dynamic power behavior enables faster initial charging for high-demand devices while maintaining long-term stability, reflecting a broader industry shift toward intelligent, adaptive GaN charging solutions.

What Is Apple’s 40W Dynamic Power Adapter with 60W Capability?
Apple’s 40W Dynamic Power Adapter is a compact charger designed with intelligent power management that allows temporary output peaks up to 60W. This is achieved through dynamic voltage scaling and real-time load detection. Once internal temperatures rise, the charger stabilizes at 40W to ensure safe and efficient operation.
From a China-based OEM manufacturing perspective, this reflects a clear evolution toward adaptive charging. At Wecent, similar designs are already implemented in GaN charger production, where smart ICs and firmware enable controlled peak power delivery without increasing device size or compromising safety.
How Does the Charger Reach 60W and Then Drop to 40W?
The charger reaches 60W by dynamically increasing voltage and current through AVS under high-load conditions. Once internal sensors detect rising temperatures, the system reduces output to 40W to prevent overheating and maintain performance stability.
In practical factory testing, this involves:
-
Load-triggered power ramp-up
-
Real-time thermal monitoring
-
Automatic power curve adjustment
Wecent applies similar calibration processes in its Shenzhen factory, ensuring every OEM charger meets both performance expectations and international safety standards.
Why Does Apple Use Thermal Throttling in Power Adapters?
Thermal throttling is used to protect internal components from overheating by reducing power output when necessary. This ensures product longevity, user safety, and compliance with certifications such as CE and FCC.
In high-density GaN chargers, heat concentration is unavoidable during peak loads. Chinese manufacturers like Wecent address this challenge through advanced thermal structures, including optimized PCB layouts and heat-resistant materials. This ensures stable operation even in compact designs.
What Is AVS and Why Is It Important in PD 3.2 Chargers?
AVS, or Adjustable Voltage Supply, allows chargers to continuously adjust voltage levels instead of relying on fixed steps. This improves efficiency, reduces heat generation, and enhances compatibility with modern devices.
Below is a comparison of traditional PD versus PD 3.2 with AVS:
Wecent integrates AVS into its OEM GaN chargers, enabling clients to deliver premium charging performance tailored to Apple and other high-end devices.
Which Devices Benefit Most from 60W Peak Charging?
Devices that require high initial power input benefit the most from temporary 60W output. These include laptops, tablets, and large-capacity power banks that demand rapid energy intake during early charging stages.
In contrast, smartphones such as iPhones typically operate below 35W, meaning they gain minimal advantage from higher peak output. This highlights the importance of dynamic power allocation in multi-device charging environments, a key focus in Wecent’s product development strategy.
How Do Chinese OEM Manufacturers Replicate This Technology?
Chinese OEM manufacturers replicate this technology by combining GaN semiconductors, intelligent power management ICs, and PD 3.2 protocol support. Firmware customization plays a critical role in defining how power is delivered and controlled.
At Wecent, production includes:
-
GaN chip integration for high efficiency
-
Firmware tuning for dynamic voltage response
-
Thermal stress testing under full load
-
Certification compliance for global markets
This end-to-end manufacturing capability allows global brands to launch competitive charging products with advanced features.
Can GaN Chargers from China Match Apple’s Performance?
High-quality GaN chargers from experienced Chinese factories can match or exceed Apple’s charging performance, especially in multi-port and high-wattage configurations. The key lies in engineering precision and component selection.
