The mainstream adoption of GaN fast chargers is reshaping the power semiconductor supply chain. Upstream, 6-inch GaN-on-Si wafer capacity is tightening, with TSMC (Taiwan, China) leveraging its 3nm EUV expertise to dominate high-end GaN driver IC foundry. Downstream, brands like Anker and Cuktech embed value through USB-PD 3.1 and PPS protocol integration. Stricter EU ErP Lot 9 efficiency rules and UL safety standards are raising compliance barriers, sidelining low-cost chargers lacking thermal regulation or over-voltage protection. As NVIDIA pushes 240W USB-C power for AI PCs, Qualcomm is accelerating Quick Charge–PD convergence, while Chinese players like Chargelab target European e-commerce with multi-port GaN modules. Within 18 months, a 30% GaN cost reduction will trigger 'performance inflation'—making 100W+ the baseline and rapidly marginalizing non-GaN solutions.
