How to choose 2021 Gan charger? Evaluation and recommendation of practical Gan charger

It has to be said that the chargers on the market are too big. Every time you go out, you have to take up a large part of the space. It's really inconvenient to carry, especially the multi port chargers. The larger the power, the larger the volume. People really want a compact multi port charger. Now due to the rapid development of technology, gallium nitride charger has appeared, which helps us solve the problem of excessive volume. Of course, I also believe that some people don't know much about gallium nitride, so I will give you a detailed explanation today. If you are interested, you can have a look.

It is simple from these aspects:

1、 The difference between Gan charger and common charger
2、 What are the advantages of Gan chargers?
3、 Recommended Gan charge
1、 The difference between Gan charger and common charger
1. The materials used are different. According to the data, the basic material used by ordinary chargers is silicon. Although silicon is a very important material in the electronic industry, with the increase of people's demand for charging, the fast charging power becomes larger and larger, so the volume of the fast charging head is larger. Even some high-power chargers charge for a long time, it is easy to cause the heating of the charging head, resulting in unsafe phenomenon, so we should pay attention to it We found a suitable alternative charger material: Gan.


2. What is gallium nitride? In short, Gan is a semiconductor material. Also known as the third generation semiconductor materials. Compared with silicon, it has better performance and is more suitable for high-power and high-frequency power devices. At the same time, the frequency of Gan chip is much higher than that of silicon, which can effectively reduce the volume of internal transformer and other components; the excellent heat dissipation performance also makes the internal components layout more precise. Therefore, Gan chargers have more advantages than traditional chargers in volume, heating and efficiency conversion, especially in high power + multi port.

2、 What are the advantages of Gan chargers?


1. Small size. If you have an ordinary charger and a GaN charger at the same time, you will find that the Gan charger is really much smaller, so we need to use it more conveniently.
2. More power. In my opinion, there are many Gan chargers on the market that provide 65W high power and meet a variety of fast charging protocols, so that even the notebook at home doesn't have to worry about charging problems. What's more, the market also provides a multi port charger, which can meet the charging needs of multiple devices.
3. It's safer. From the above explanation, gallium nitride has super thermal conductivity and better heat dissipation function, so gallium nitride charger will be safer to use.

3、 Multi port Gan charger recommended. (I believe you have a lot of equipment at home, so I'll go straight to the topic and recommend many brands. Of course, if you want to single port, you can skip this section and see the recommendation of the next section!)


Bess 100W Gan four port fast charging
In the aspect of modeling design, it can be seen from the figure that Beisi provides four interfaces. They are two type-C ports and two USB ports, which can charge four devices at the same time. And its overall size is not big at all, even smaller than the original charger of Apple's 61W MacBook Pro notebook. At the same time, in order to further save the space of the charger, this charger uses a folding pin design, which can not only save space, but also avoid the damage of the charger pin in the extrusion environment.

Secondly, in terms of charging speed, Bess Gan fast charging is also very strong. The double type-C blind charging is 100W, which can meet the needs of most notebook PD fast charging; the double USB blind charging is 60W, which supports the fast charging of mainstream models such as Huawei, Samsung and Xiaomi. If multiple devices are charged together, this 100W four port charger is perfect. Of course, I'd like to show you in detail which fast charging protocols are supported by Bess Gan fast charging, as shown in the figure below:

Finally, Bess Gan fast charging is very safe to use. When multi-channel charging, Bess will adopt intelligent dynamic distribution technology to ensure safe charging, and has six safety protection measures, such as overvoltage protection, overcurrent protection and short-circuit protection, which also make us feel more at ease.
Nubia 65W Gan charger
Nubia this is a square column shape, the overall body is silver gray with black bottom shell, it looks quite atmospheric, and its volume has been streamlined again, compared with similar three port charger, it is more compact.
Its output is equipped with 2c1a three interfaces, each interface is printed next to the logo to distinguish, more intimate. Moreover, both C ports support power blind plug-in function. If you plug in any usb-c interface separately, you can get the same performance, so you can use it freely. Usb-a port supports a variety of fast charging protocols, so the speed is not slow at all.
In addition, Nubia adopts neocharger heat dissipation technology to accelerate heat diffusion and efficiently dissipate heat. And I especially like its trickle mode. Whenever the mobile phone is nearly full, it will automatically switch to protect the battery health, so that the mobile phone can be used for a long time.
Gan X65 Gan charger
The design of lvlian is more square and compact. It is said that laser texture processing is adopted on the front and back to increase the feel and aesthetic feeling. And it provides four interfaces, which support qc2.0/3.0, AFC, FCP, SCP, MTK PE + 2.0 fast charging protocol. Usb-c1 / C2 port has 5v3a, 9v3a, 12v3a, 15v3a, 20v3.25a and 3.3-21v/3a voltage range. The overall compatibility of the product is very good, which can meet the charging requirements of most mobile phones and thin laptops.
In addition, as can be seen from the internal structure diagram provided by Greenlink below, this Gan charger of Greenlink does not pursue the ultimate small size, but adopts the traditional tile circuit board structure design. Compared with the stacked circuit board structure, the tile structure has the advantage of leaving a certain space between the various parts to avoid heat accumulation, improve the overall heat dissipation effect, and achieve the goal of low temperature and fast charging Yes.
summary
The above is my recommendation! It can be said that each has its own characteristics and advantages, and they are very easy to use. In addition, I think it is necessary to buy a multi port Gan charger to save a lot of energy if you often travel on business or travel or have more equipment at home. If you don't have much equipment and don't go out much, the original equipment will be enough. Of course, if you like gallium nitride charger, I'm not asking you not to buy it. In short, I'll decide according to the demand.
