Analysis of the industry chain, supply and demand status, and development trends of China's power adapter industry in 2025

1. Power adapter industry

A power adapter refers to an accessory device that comes with electronic products or an electronic device purchased separately that can be used to charge certain household appliances. In general, it is an electrical accessory product whose main function is to convert alternating current (AC) into low-voltage direct current (DC).

II. Industrial Chain of the Power Adapter Industry

The upstream of the power adapter industry chain mainly includes semiconductor devices, magnetic components, passive components and structural parts, and auxiliary materials. Among them, magnetic components include transformers, inductors, magnetic rings, etc., while passive components include capacitors, resistors, fuses, etc. Structural parts and auxiliary materials include plastic casings, heat sinks, insulating materials, cables, etc. The midstream involves the design, production, and assembly of power adapters. The downstream terminal applications include consumer electronics, communication equipment, new energy and automotive electronics, industry, and healthcare.

III. Current supply and demand situation of the power adapter industry

In recent years, with the rapid development of technologies such as intelligence, the Internet of Things, and 5G communication, the demand for power adapters from various intelligent terminal devices has continued to rise. The large user base and demand for electronic products have become the foundation for the expansion and development of power adapter products. According to statistics, as of 2024, the output of China's power adapter industry was 1,512,675,000 units, and the demand was 1,439,690,000 units.

IV. National Supervision and Random Inspection

With the diversification of intelligent electronic products and the increase in the autonomy of online shopping, consumers have raised higher requirements for the quality and safety of power adapter products. Product safety has also become the core issue of primary concern for consumers. In 2024, the State Administration for Market Regulation conducted a spot check on 69 batches of products from 52 sales units in six provinces (cities) including Jiangsu, Guangdong, Zhejiang, Beijing, Anhui, and Hebei. The products involved were manufactured by 68 production units in eight provinces (cities) including Guangdong, Beijing, Zhejiang, Shanghai, Fujian, and Hunan. The spot check found that six batches of products were unqualified, with an unqualified rate of 8.7%.

V. Trends in the power adapter industry

1. Miniaturization

With the widespread use of portable electronic devices, there is an increasing demand for power adapters with higher portability. The application of new semiconductor materials such as gallium nitride (GaN) and silicon carbide (SiC) will drive the development of adapters towards smaller size and higher power density, making them more convenient to carry and use.

2. Intelligentization

Power adapters are gradually evolving towards intelligence, integrating smart chips to enable functions such as device recognition and power adjustment. In the future, power adapters may also connect to the Internet, enabling remote monitoring, intelligent adjustments, and more, providing users with a more convenient and intelligent charging experience.

3. Emergence of emerging fields

With the continuous growth of the consumer electronics market, the rapid development of the new energy vehicle market, and the widespread adoption of smart grids and smart home applications, the application scenarios of power adapters will continue to expand. Furthermore, the advancement of human-computer interaction technology, novel sensing technologies, and data fusion techniques will also spur the emergence of more emerging electronic products, presenting new growth opportunities for the power adapter market.
