According to a new report from Intel Market Research, global AC-DC External Power Supply (EPS) market was valued at USD 10,310 million in 2024 and is projected to reach USD 9,865 million by 2032, declining at a CAGR of -0.6% during the forecast period (2025–2032). This slight contraction is influenced by several factors, including the gradual integration of power supplies directly into devices and extended life cycles for many electronics.
An AC-DC External Power Supply (EPS) is a power adapter designed to supply electric energy by converting line voltage alternating current (AC) input into regulated lower voltage direct current (DC) output for powering consumer electronics, IT equipment, and industrial devices. An EPS unit serves as the intermediary between a wall outlet and an electronic device, ensuring safe and efficient power conversion while meeting global energy efficiency standards. These devices are essential for smartphones, laptops, network equipment, and numerous other applications where device-specific power requirements exist.
This report provides a deep insight into the global AC-DC External Power Supply (EPS) market covering all its essential aspects—from a macro overview of the market to micro details such as market size, competitive landscape, development trends, niche markets, key drivers and challenges, SWOT analysis, and value chain analysis.

1. Proliferation of Electronic Devices and Connectivity
The explosive growth in consumer electronics—including over 1.5 billion smartphones shipped annually—creates continuous, high-volume demand for compatible power adapters. The increasing number of connected devices per household and continued innovation in product features necessate reliable external power solutions, sustaining the market despite overall contraction trends.
2. Stringent Global Energy Efficiency Regulations
Regulatory mandates from bodies like the US Department of Energy (Level VI standards) and the European Commission's Ecodesign Directive compel manufacturers to produce more efficient EPS units. This regulatory push drives replacement of older, inefficient power supplies, with estimates suggesting regulations could prompt the upgrade of over 500 million units globally in the next five years, providing a counterbalance to market decline through forced obsolescence cycles.
Early market developments have shown promising outcomes in:
Power-Dense Design Convergence – The adoption of wide-bandgap semiconductors like GaN enables development of smaller, lighter adapters without sacrificing performance, particularly for laptop and gaming applications where portability is paramount.
These regulatory and technological factors highlight the EPS market's ongoing evolution toward higher efficiency and compact form factors, maintaining relevance despite integration trends.
Market Challenges
Intense Price Competition and Commoditization Pressure – The highly competitive landscape, especially in Asia, leads to intense margin pressure. Because the market is often viewed as a commodity space, it becomes challenging for companies to differentiate based on features beyond price.
Complex Global Compliance Landscape – Manufacturers must navigate varying regional safety, EMC, and energy efficiency standards (UL, CE, CCC, KC), representing a significant operational and financial burden.
Rise of Integrated and Universal Power Solutions – The trend toward USB Power Delivery (USB-PD) as a universal standard could gradually reduce demand for device-specific external power supplies.
Emerging Opportunities
The power supply market is adapting to new technological paradigms. While integrated solutions present challenges, they also create opportunities for manufacturers who can innovate within emerging sectors. Key growth enablers include:
Implementation of wide-bandgap semiconductor technologies (GaN/SiC)
Expansion into Electric Vehicle (EV) Supporting Infrastructure – This includes portable EV chargers and various auxiliary power supplies needed for EV charging infrastructure.
Formation of strategic alliances with regional distributors, healthcare institutions, and academic partners across developing regions.
Collectively, these industry shifts are expected to maintain specialized demand, drive innovation in premium segments, and open new application areas beyond traditional consumer electronics.
