In recent years, gallium nitride PD fast charging chargers have sprung up like mushrooms on the market, and various brand manufacturers have launched their own gallium nitride USB PD chargers. But for ordinary users, they have very little knowledge about gallium nitride chargers and cannot distinguish the difference between ordinary chargers and gallium nitride chargers. Why is the price of gallium nitride chargers, which have the same appearance as ordinary chargers, much higher than that of ordinary chargers?

Gallium nitride is a new type of semiconductor material with characteristics such as wide bandgap, high thermal conductivity, high temperature resistance, radiation resistance, acid and alkali resistance, high strength, and high hardness. It was widely used in new energy vehicles, rail transit, smart grids, semiconductor lighting, and new generation mobile communication in the early days, and is known as the third-generation semiconductor material. With the breakthrough of technology and cost control, gallium nitride is still widely used in consumer electronics and other fields, and chargers are one of them. Simply put, gallium nitride has a wider bandgap, which means that gallium nitride can withstand higher voltages than silicon and has better conductivity. Under the same volume, chargers using gallium nitride technology have higher output efficiency than ordinary chargers. For example, a charging head made of gallium nitride material, with a volume similar to that of an Apple 5W charger, can achieve more output power.
