What is GAN techolonogy for the chargers?

To put it simply, a small body with high power.

Gallium nitride (GaN) chargers made a big splash at the International Consumer Electronics Show, and this modern silicon alternative means that smaller, more efficient chargers and power supplies are coming out.

GaN chargers are physically smaller than current chargers, because GaN chargers do not require fewer components than silicon chargers. This material can conduct much higher voltages than silicon over time. GaN chargers are not only more effective in transferring current, but also mean less energy is lost to heat. Therefore, when components are more efficient in transferring energy to the device, fewer components are usually needed. As a result, with the widespread popularity of technology, GaN power supplies and chargers will be significantly reduced. There are other benefits, such as higher switching frequency can achieve faster wireless power transmission.

Gallium nitride is a semiconductor material that became the focus of attention in the 1990s by manufacturing LEDs. GaN was used to create the first white LEDs, blue lasers and full-color LED displays that can be seen during the day. In Blu-ray DVD players, GaN produces blue light, which reads data from the DVD.

It seems that GaN will soon replace silicon in many areas. Silicon manufacturers have worked tirelessly for decades to improve silicon-based transistors. According to Moore's Law, the number of transistors in integrated silicon circuits doubles approximately every two years. This observation was made in 1965 and has been basically correct for the past 50 years. However, in 2010, the development of semiconductor technology fell below this speed for the first time. Many analysts (and Moore himself) predict that by 2025, Moore's Law will be obsolete.

The production of GaN transistors increased in 2006. The improved manufacturing process means that GaN transistors can be manufactured in the same type of equipment as silicon. This can reduce costs and encourage more silicon manufacturers to use GaN to produce transistors.
