Introduction
Qi2 is the next-generation wireless charging technology standard launched by the Wireless Power Consortium (WPC). The Qi 2.0 standard was released in 2023, introducing MPP and increasing wireless charging power to 15W. According to the latest information, the WPC released the newer Qi 2.1 standard at the end of 2024 and plans to introduce the Qi 2.2 standard in 2025.
The Qi 2.1 standard introduces auto-alignment functionality and magnetic phone case technology, significantly improving device alignment accuracy and compatibility, while also optimizing performance for specific scenarios like in-vehicle wireless charging. The Qi 2.2 standard, breaking new ground, increases charging power to 25W, once again upgrading wireless charging speed and providing robust technical support for building a more efficient, safer, and more flexible wireless charging ecosystem.
As a leading enterprise in the wireless charging industry, NuVolta has participated in advancing the Qi2 standard and was among the first globally to have self-developed modules pass Qi2 certification. Recently, they launched two wireless charging modules based on the latest Qi 2.2 standard. ChargerLAB provides a detailed introduction below.
NuVolta Qi 2.2 Modules
NuVolta's MPP 25W fast charging module series primarily includes two core products: the Nu300 and Nu325. These modules support multi-protocol modes compliant with the latest wireless charging technology standards, including MPP 25W/15W and EPP 15W. Through high-power output and advanced magnetic design, these modules provide an efficient and convenient wireless charging experience for end devices like smartphones.
Nu300
The Nu300 module supports input voltages of 5V/3A, 9V/3A, and 15V/3A, with a maximum output of up to 25W, making it suitable for modern high-power demand devices. The module has a diameter of 58.56mm and a thickness of only 7.9mm, with an adsorption force of up to 900gf, ensuring a stable connection during charging while preventing accidental slippage of the device. Its design balances performance and appearance, making it suitable for various portable and fixed wireless charging application scenarios.
Nu325
Building upon the Nu300, the Nu325 module is further upgraded with an integrated active cooling system to optimize temperature management during charging, enhancing overall efficiency and safety, and providing greater durability. The Nu325 is slightly larger, with a diameter of 65.2mm and a thickness of 8.9mm. It also supports input voltage levels of 5V/3A, 9V/3A, and 15V/3A, and can achieve an output power of up to 25W. Its maximum adsorption force is also 900gf, ensuring a stable magnetic attachment. This product is suitable for scenarios requiring sustained high-power output, such as desktop fast charging stations or in-vehicle wireless charging devices.
Furthermore, this series includes related accessories like the NU325-PAD aluminum series and the NU325-FAN super cooling system, offering different color options (e.g., black, green, purple, etc.), adding personalized choices beyond functional practicality. The design of these modules and accessories combines high performance, compatibility, and aesthetics, meeting the current wireless charging market's demand for high efficiency and diversified products.
