One of the most innovative recent technologies is the refill GaN, that is the one that allows us to charge our devices (mainly smartphones and PCs) with more efficiency and speed. There are many companies that have started to use it and among these we cannot mention Oppo e Xiaomi. The first of these two uses the technology in question on the 65W SuperVOOC Fast Charge 2.0; the second, on the other hand, presented numerous chargers of this kind, with more or less variable powers. But please, how it works and what is this technology? Let's try to understand it together.

Everything you need to know about Gallium Nitride GaN technology: how it works, what it is, disadvantages and advantages
The recharge GaN we can say that it will be standards of the future, before normal becomes wireless. But let's go in order and start from the definition. The is not an acronym but the chemical formula of gallium nitride, semiconductor used in electronic devices. As it is easy to guess is the material used in the chargers for smartphones and PCs. Initially this material was used for the manufacture of LED but then he also worked for solar panels.
Gallium nitride is a crystal-like material from the point of view of internal construction, but capable of conduct a much higher voltage. Current can pass through gallium nitride components faster than silicon components, resulting in even faster processing time.
What are the advantages of GaN?
We will certainly have understood that the advantage is not just one. We list them below:
- space: if there are several elements inside a transistor (i.e. a component of the charger), it means that these can be close together and this results in a reduction in the measurements of the charger itself
- power: as we said the power increases by virtue of the ability to pass more electric current
- time: directly proportional to the power, it is the time factor. This is clearly reduced to make a device (smartphone or PC that is) recharge faster
- connector: Another advantage of chargers of this type is that they can charge all mobile devices via a USB Type C port
- life: by increasing the resistance and therefore decreasing the temperature, the life of the chargers increases considerably
Is my smartphone compatible?
Most smartphones are equipped with a temperature control. This means that if a device with support for maximum charging 18W is connected to a 65W GaN charger, the device will warn that a problem is in progress. compatibility. Anyhow we strongly advise against using such a charger on a smartphone that does not support ultra-fast charging.
most GaN chargers integrate the technology USB-C PowerDelivery. This allows us to offer faster recharging for i compatible devices. Most smartphones today support a fast charging standard, and more and more devices will offer this option in the future.
