Laptop chargers are becoming significantly smaller and lighter due to the adoption of Gallium Nitride (GaN) semiconductor technology. GaN semiconductors are more efficient than traditional silicon, allowing for more compact components and reduced heat generation. This advancement enables GaN chargers to deliver higher wattages (40W-150W) with up to 99% efficiency, compared to silicon's 85%. While GaN chargers can be more expensive, their prevalence is increasing across major laptop manufacturers and accessory brands, making bulky chargers a relic of the past. AI
