Power Adapters (USB-C, etc.): Market Size & Forecast 2026

The global power adapter market for USB-C and AC-DC wall chargers sits at approximately USD 28.5 billion in 2025, growing to roughly USD 45.2 billion by 2032 at a 6.8 percent CAGR. The market is structurally tight between rising GaN-based fast-charger demand, the EU common charger mandate taking effect in April 2026, and concentrated upstream semiconductor supply. The dominant supply-side constraint is not chassis or passive components; it is GaN power semiconductor availability, where three primary wafer suppliers anchor roughly 70 percent of global epi-wafer capacity. The US landed-cost structure faces a combined Section 122 (10 percent) plus Section 301 List 3 (25 percent) ad valorem tariff stack on China-origin adapters and subassemblies under HTS 8504.40. > **Analyst Take.** The consensus 7 percent-plus CAGR on this category deserves pushback. A 7 percent CAGR implies value doubling
