Part 1: What is a Gallium Nitride (GaN)) Charger?

You might be curious about this new noun which looks and sounds so unfamiliar to most people -- a Gan Charger. To put it more seriously, it is a GaN Charger, using gallium nitride as a semiconductor that is able to produce chips for electronics. GaN itself is a transparent crystalline material, which, in its early stage, has been used frequently in LEDs production since it's capable of producing violet laser diodes. So, why is GaN now used in the field of chargers?

Let's put this simply, a charger applies a current to a battery in an attempt to reverse a chemical reaction inside each one while gallium nitride is so capable of delivering high quantities of power to devices. So it is obvious that using gallium nitride in a charger does benefit you in some ways, like it does a better job preventing overcharging to safeguard the battery, on the other hand, it delivers a fast charging and a large amount of power while staying a compact size itself. All this just meets the needs of a practical and high-performance charger nowadays. This very new Gan Charger is cut out for the job in lieu of early chargers.
