Global AC-DC External Power Supply (EPS) Market Growth 2025-2031

The global AC-DC External Power Supply (EPS) market size is predicted to grow from US$ 10990 million in 2025 to US$ 10580 million in 2031; it is expected to grow at a CAGR of -0.6% from 2025 to 2031.

An AC-DC External Power Supply (EPS) is a device that converts alternating current (AC) from a mains power source into direct current (DC) to power electronic devices. Typically housed in a separate unit from the device it powers, an EPS provides the necessary voltage and current required for operation. Commonly used for laptops, smartphones, and other consumer electronics, it ensures safe and efficient power conversion while often incorporating features like over-voltage protection and energy efficiency compliance.

Global AC-DC External Power Supply (EPS) key players include Delta(Eltek), Lite-On Technology, Acbel Polytech, Salcomp, Chicony Power, etc. Global top 5 manufacturers hold a share over 20%. Asia-Pacific is the largest market, with a share about 58%, followed by North America and Europe, with a share about 25% and 12%.

The market drivers for AC-DC External Power Supplies (EPS) primarily stem from the continuous growth in global demand for electronic devices, particularly the widespread adoption of smartphones, laptops, tablets, IoT devices, and consumer electronics. Additionally, the push for energy conservation and emission reduction policies, along with the enhancement of energy efficiency standards (such as Energy Star and the EU ErP Directive), has encouraged manufacturers to adopt more efficient and environmentally friendly power solutions. Meanwhile, the popularity of fast-charging technologies and the diversification of portable devices have further fueled the expansion of the EPS market, with increasing consumer demand for high-efficiency, lightweight, and multi-functional adapters.

The AC-DC External Power Supply (EPS) market is moving towards higher energy efficiency, miniaturization, intelligence, and wireless capabilities. With the application of new semiconductor materials like GaN (gallium nitride) and SiC (silicon carbide), the power density and efficiency of EPS have significantly improved, while their size and weight have been reduced. Furthermore, the rise of smart power adapters, which support dynamic power adjustment and remote control functions, meets the needs of IoT and smart home devices. The rapid development of wireless charging technology has also brought new growth opportunities to the EPS market. In the future, the market will place greater emphasis on green environmental protection, multi-functional integration, and enhanced user experience.
