External AC-DC Power Supply Market was valued at 10320 million in 2024 and is projected to reach US$ 9584 million by 2032, at a CAGR of -1.1% during the forecast period.
An External AC-DC Power Supply is a type of external power supply (EPS) unit designed to convert alternating current (AC) line voltage input into a lower voltage direct current (DC) output. These devices are critical for powering a vast array of consumer electronics, IT equipment, and industrial applications, providing a safe and efficient method to deliver electric energy externally to a device.
This projected market contraction is primarily driven by increasing regulatory pressure for energy efficiency and a growing industry shift towards integrated power solutions that eliminate the need for external bricks. However, the market remains substantial due to the sheer volume of existing devices that require them. The market is highly concentrated, with the top two players, Delta (Eltek) and Lite-On Technology, collectively holding approximately 40% of the global market share. Geographically, China dominates as the main production and consumption hub, accounting for about 50% of the global market. In terms of product segmentation, low-power units (Up to 10W) are the predominant type, representing nearly 60% of the market, largely driven by their use in mobile phones and other portable electronics. The Mobile Communications sector is the leading application segment, holding a significant share of about 40%.
