Approximately 4% current share reflects the region's smaller manufacturing base, but demand growth is supported by expanding technology adoption. High ambient temperatures also increase the importance of thermal efficiency and reliable component design in external power supplies.

Africa remains at an earlier stage of EPS adoption but offers long-term potential as mobile connectivity, broadband access, digital payments, healthcare electronics, and distributed energy systems expand. South Africa, Egypt, the United Arab Emirates, and Saudi Arabia are among the more developed markets for electronic equipment and power-conversion products. Telecom devices and consumer electronics remain major demand drivers, while medical and industrial applications provide higher-value opportunities. Approximately 12% of recent regional product demand growth is associated with networking, surveillance, and connected infrastructure equipment. Distribution reliability and product authenticity remain important challenges in some markets, creating opportunities for established suppliers with certified products and stable channels. Middle East & Africa is therefore expected to expand gradually as digital infrastructure improves and demand shifts toward more efficient, compact, and standardized AC-DC external power supply solutions.
