Different materials
Ordinary chargers: use silicon as the core semiconductor material. Silicon is the traditional and mature technology, but under high frequency and high voltage, it is less efficient and generates more heat.
Gallium Nitride Charger: Gallium Nitride is used as the core semiconductor material. Gallium nitride is a new type of semiconductor material with excellent characteristics such as large forbidden band width, high thermal conductivity, high voltage resistance and radiation resistance.
It is this difference in the core material that gives rise to all the differences in user experience below.
1. Volume and weight (the most intuitive difference)
Ordinary chargers: Due to the physical limitations of the silicon material, in order to achieve high power output, it is necessary to use a larger volume of transformers and capacitors and other components, resulting in a large and heavy charger. Our former laptop “big brick” charger is a typical representative.
Gallium Nitride chargers: Gallium Nitride components can operate at higher frequencies, which means smaller transformers and capacitors can be used. As a result, at the same power, GaN chargers can be made 30% - 50% smaller than normal chargers, making them very lightweight and easy to carry.
