New chargers based on GaN technology

Today, the most digitized people carry tablets, smartphones, notebooks and wireless headphones in their backpack and all these devices need their own power supply. Therefore, all these technological products have both a significant weight and size.  

Some electronics companies such as Aukey, Eggtronic and Anker have already launched on the market some innovative chargers that are based on GaN (Gallium Nitride) technology. But let’s see why these chargers could conquer users and revolutionize the world of power supplies. As it is well known, these devices are usually made of silicon and are also quite bulky and heavy, but recently another element that could replace it has come into play, we are talking about gallium nitride. 

GaN is a very useful semiconductor in the production of electronic devices and already used in the military and aerospace industries. But what are the positive aspects of this element? It is true that, compared to silicon, it is more expensive, but it has many characteristics that should not be underestimated. First of all, it promises a higher charging speed, does not overheat and is more efficient as it consumes less energy, unlike silicon which dissipates a large amount of heat into the environment. According to a physicist at the University of Bristol, there could be a reduction in energy consumption between 10% and 25% if all the devices worked with gallium nitride technology. 

To help reduce environmental impact, Apple was the first brand to eliminate power supplies from the packaging of the latest iPhone models. Despite this, the Cupertino company, but also the famous Samsung and Huawei ones, are working to design new chargers based on GaN technology. Whereas Xiaomi, a Chinese company, has already launched a charging device on the market that is able to fully charge a Mini Note 10 Pro in only 45 minutes and another very interesting aspect is the fact that this power supply, compared to a “classic” one, has a reduced volume of almost 50%. 

If GaN will become the “silicon of the future”, as many people state, then not only will users have lighter, more efficient and less bulky devices, but also the environment around us will benefit from it.
