1、 Technological innovation: Gallium nitride efficiency revolution, fast charging power repeatedly breaking records

Gallium Nitride Technology Breaks Efficiency Ceiling
Global power semiconductor company Transphorm and Weiquan Electronics jointly launch 100W USB-C PD power adapter, using innovative SuperGaN ®  SiP technology achieves a peak efficiency of 92.7% (under 264VAC full load conditions) in a quasi resonant flyback topology, improving energy efficiency by more than 15% compared to traditional solutions. This technology simplifies circuits through integrated design without the need for additional protective components, reducing the cost of 100W adapters by 30% and providing a cost-effective solution for consumer electronics and AI data centers. Fast charging technology reaches new heights
In the field of consumer electronics, the USB-C PD 3.1 standard now supports 240W power output, compressing the charging time of smartphones and ultrabooks to within 15 minutes.
Advanced gaming equipment: By 2025, the power of gaming laptop adapters may exceed 400W to meet the power demand of high-performance GPUs.
Industrial and Data Centers: NVIDIA AI servers are driving up power density, with a surge in demand for 5.5kW AC/DC modules. It is expected that the market size will reach 34.3 billion yuan by 2025, with a compound annual growth rate of over 150%.
Testing technology patents enhance quality standards
The "Swing Testing Method and Equipment" patent developed by Jiangxi Haoliwei Electronics can accurately predict potential fault points by dynamically simulating adapter usage scenarios, combining sound monitoring and swing frequency analysis, reducing mechanical durability evaluation errors to less than 5%, and providing a new paradigm for industry quality control.
2、 Market size: Asia as the main engine, with explosive growth in segmented fields

Global demand continues to rise
Total volume: The global adapter market is expected to exceed 18.5 billion US dollars by 2025, with a year-on-year growth of 8.2%.
Regional differentiation: The Chinese market accounts for over 40%, while demand growth in India and Southeast Asia reaches 12%; The European and American markets focus on high-end customized products, such as medical equipment adapters, with an annual growth rate of 18%.
Emerging application scenarios emerge
New energy vehicles: The demand for 800V high-voltage fast charging pile adapters and on-board power supplies has surged, and modular design supports a power output of 350kW.
Whole house intelligence: The popularization of Matter protocol is driving the growth of smart home adapter shipments, expected to reach 230 million units by 2025.
Industry 4.0: The stability requirements for automation equipment have increased, and the demand for customized power sources has grown by 25%. The medical and communication base station fields have become the main battlefield.
3、 Policy driven: Upgrading energy efficiency standards and accelerating green transformation

The new version of China's energy efficiency national standard has been implemented
The GB 20943-2025 standard will be fully implemented in 2027, mandating the use of third-generation semiconductor devices for adapters, with energy efficiency levels divided into four categories, and the addition of multiple load combination tests. Compliant products must pass Level 3 energy efficiency certification, and those that do not meet the standards are prohibited from being listed. This move will raise the industry entry threshold by 30% and is expected to eliminate 20% of low-quality production capacity. Global environmental regulations are becoming stricter
EU: The ErP directive requires adapters to have a standby power consumption of less than 0.1W, forcing companies to adopt low-power chips.
The United States: DoE energy efficiency standards are mutually recognized with GB 20943-2025, reducing the cost of certification for Chinese products going abroad.
Domestic "dual carbon" target: Government procurement prioritizes the use of 80 Plus certified products, and the market share of green adapters is expected to soar from 15% in 2024 to 35% in 2025.
4、 Manufacturer dynamics: Local enterprises rise, technology cooperation deepens

Top manufacturers accelerate layout
Leyong Times, Runzhong Electronics, Xinsibao, and others will release 330W ultra-high power adapters at the 2025 Asia Charging Expo, supporting AI notebook fast charging and passing 12 international certifications such as CQC and ETL.
Eurofins plans to mass produce 400W gallium nitride adapters by 2025, aiming to capture 20% of the gaming market share.
Hangjia has reached a cooperation agreement with Nvidia to provide 5.5kW liquid cooled power modules for AI servers, with an expected annual revenue contribution of over 500 million yuan.
International cooperation promotes technological upgrading
Transphorm: The gallium nitride solution jointly developed with Weiquan Electronics has obtained supply chain certification from Xiaomi and Lenovo, and is expected to ship 5 million chips by 2025.
Jiangxi Haoliwei: Swing testing patent attracts Huawei and Dell to participate in equipment procurement, with order volume increasing fourfold compared to 2024.
5、 Future outlook: Intelligence and sustainability become the core tracks

Technology Trends
AI Empowerment: The adapter is equipped with an intelligent chip that supports device recognition and dynamic power allocation, improving charging efficiency by 10% -15%.
Wireless charging: Long distance wireless charging technology is gradually being commercialized, and the adaptive power may exceed 50W.
Market pattern
Domestic substitution acceleration: Domestic enterprises rely on cost advantages and technological breakthroughs, and are expected to occupy 50% of the global market share by 2025.
Emerging market breakthrough: Africa and South America have huge demand growth potential, and Chinese manufacturers are expected to contribute 10% increase through the "the Belt and Road" layout.
