100W USB-C GaN Charger (20V 5A PD) for Laptops and High-Power Devices

The 100W USB-C GaN Charger is a high-efficiency power adapter designed for modern high-power USB-C devices. Built with advanced GaN (Gallium Nitride) technology, it delivers stable and efficient power output up to 100W with support for 20V/5A USB Power Delivery (PD 3.0).

Compared with traditional silicon chargers, this GaN charger offers higher power density, lower heat generation, and a significantly more compact design, making it ideal for both portable use and OEM integration.

Learn more about the differences between GaN and traditional silicon chargers in our detailed guide: “GaN vs Silicon Chargers – Key Differences and How GaN Works”.

It is widely used for high-performance laptops, USB-C docking stations, and industrial electronic devices requiring reliable high-wattage USB-C power delivery.
