GaN Semiconductors Shrink Laptop Chargers by Up to 50 Percent

Executive Briefing

• Replaces silicon semiconductors, GaN technology enables laptop chargers to shrink 40–50% while delivering 40W–150W
• Offers up to 99% efficiency versus ~85% for silicon, reducing heat and enabling faster charging speeds
• Adopted widely by Apple MacBook Pro, Lenovo, Dell, and accessory makers like Anker for premium models
• Costs more than silicon chargers currently, though price gap is narrowing as mass adoption accelerates
• Provides added benefits including multi-device USB ports, furniture-friendly compact size, and improved energy efficiency
