What Is GaN Charger? Exploring the GaN Technology.

Hey, guys. It’s Welink there. We hope you have a nice day today.
What are you thinking about now when you see here?
What Is GaN Charger?
Okay, It is the question where we start. Let’s see.

What is GaN Technology?

Gallium Nitride (GaN) is a compound of Nitrogen and Gallium with specific semiconductor characteristics. It belongs to the same periodic group of elements as semiconductor silicon. Gallium Nitride (GaN) is a new type of semiconductor material, which has the characteristics of wide bandgap, high thermal conductivity, high temperature resistance, radiation resistance, acid and alkali resistance, high strength and high hardness.

Applications of GaN

In the early days, due to significantly improved efficiency and higher switching frequencies, Gallium Nitride (GaN) was widely used in the aerospace, new energy vehicles, rail transit, smart grid, semiconductor lighting, and new-generation mobile communications. It is called the third-generation semiconductor material.

With technological breakthroughs and cost control, Gallium Nitride (GaN) is also widely used in consumer electronics and other fields, and chargers are one of them. In the charger, it is mainly integrated with Gallium Nitride MOS tube, which can be adapted to small transformers and high-power devices.

Why is Gallium Nitride (GaN) Superior to Silicon?

At present, silicon is reaching its limits in terms of efficiency and power levels. The Industry has begun to work hard to find more suitable substitutes. So, we added GaN technology.

As GaN Systems, a manufacturer that specializes in Gallium Nitride (GaN), explained:
“All semiconductor materials have what is called a bandgap. This is an energy range in a solid where no electrons can exist. Simply put, a bandgap is related to how well a solid material can conduct electricity. Gallium Nitride (GaN) has a 3.4 eV bandgap, compared to silicon’s 1.12 eV bandgap. Gallium Nitride (GaN)’s wider bandgap means it can sustain higher voltages and higher temperatures than silicon.

A higher bandgap efficiency means the current can pass through a GaN chip faster than a silicon one. This could result in faster processing capabilities in the future. Simply put, chips made of GaN will be faster, smaller, more power-efficient, and (eventually) cheaper than those made of silicon.

The Advantages of GaN Charger

Reduced Size

GaN chargers are physically smaller than current silicon chargers. Compared with silicon chargers, GaN chargers require fewer components and the Gallium Nitride MOS is much smaller in size than traditional silicon-based.

Increased Efficiency

GaN chargers are more efficient in transferring current and conserving energy. Conserved energy enables a better flow to the charging device, resulting in quicker charge times. High efficiency and less charging time.

Improved Heat Dissipation

Semiconductors and chargers made with Gallium Nitride (GaN) tend to be smaller and more efficient, making them less vulnerable to heating up.

Saved Electricity

A bit of money might be saved on power bill since more efficient chargers mean less wasted electricity energy.

The Future of GaN Charger

As a new third-generation semiconductor material, Gallium Nitride (GaN) has high requirements for the synthesis environment. In terms of manufacturing process, gallium nitride has no liquid state and is synthesized purely by gas reaction. Therefore, the cost of Gallium Nitride (GaN) is higher and the price of GaN chargers on the market is also higher than that of the traditional silicon chargers.

At present, GaN semiconductors generally cost more than the silicon kind. However, due to improved efficiency, there’s a reduced reliance on additional materials, like heatsinks, filters, and circuit elements. With the development of Gallium Nitride (GaN) technology, the cost of GaN Charger is coming down gradually.


In short, The chargers made of GaN can provide faster charging speed, higher power efficiency and better thermal efficiency all in a smaller size than traditional silicon chargers. GaN is becoming a new charging technology used in the GaN chargers to greatly enhance power efficiency. In fact, the GaN charger has already become a growing player in the fast charging space. After all, it’s smaller, more power-efficient and safer than its predecessor.

Although its price is a bit higher, it’s still worth being your next smartphone charger. So if you do decide to enjoy its charging benefits, give it a try.

The advantages of GaN Charger can be summarized as follows:

  • High charging conversion rate
  • Fast charging speed
  • Small size and light weight
  • Less heat when charging
  • Low loss during charging and discharging
  • High efficiency and less charging time
