Gallium nitride is actually GaN Is a compound of nitrogen (N) and gallium (Ga) A new type of semiconductor material that can replace silicon and germanium

The characteristics of gallium nitride can effectively reduce the volume ︑ reduce heat generation ︑ increase efficiency ︑ reduce loss The difference between GaN chargers and traditional chargers is that they are small in size and high in power.

First of all, we must first understand from the material Gallium nitride is a new type of semiconductor material From the first generation of silicon (Si), the second generation of gallium arsenide (GaAs), To the third generation of silicon carbide (SiC) and gallium nitride (GaN) The third generation of semiconductors is also known as wide band gap semiconductors Compared with previous semiconductors, it can withstand high temperature ︑ high voltage ︑ high frequency ︑ high current
Therefore, it can achieve the effect of reducing volume ︑ reducing heat generation ︑ improving efficiency ︑ reducing loss



Although our main purpose in this article is to mention the relationship between gallium nitride and charging But the characteristics of high power and small size are not only used in charging related There are many other application areas What I want to emphasize here is: GaN is not only used as a charger!

Then again... what are the characteristics of GaN in the charger? If you want to know what the features are, you must first have a little idea about the existing charger!

Let’s first discuss the devices that need to be charged in daily life. Take Apple users as an example: mobile phones︑laptops︑tablets︑Airpods The required charging wattage is as follows



Generally, there are also devices that may be used: Power Bank︑Bluetooth Audio︑Switch If you are a user who often needs to bring several devices or more


Do I need to bring a lot of charging combinations to go out? The charging cable is small because of its small size and light weight

The problem is the charging head. The higher the wattage, the larger the charging head. Take two or three sets when you go out, a backpack may be full

At this time, the gallium nitride charger is a great choice!!! The volume of the charging head is definitely smaller than the average

The number of charging holes is definitely more than the original charging head Practicality is also much higher


As long as you have a gallium nitride charger, almost all devices are suitable In the future, you won’t have to take many chargers out of the house.
