How about the green link charger?
1、 Gallium nitride (GAN) era: charger volume increases instead of decreasing?
In recent years, the most popular concept in chargers is Gan, the third generation semiconductor material. GaN has high stability. After Gan is used in rectifiers of chargers, it can reduce switching loss and driving loss, increase switching frequency, and reduce waste heat generation incidentally, so as to reduce the volume of components and improve efficiency.
The application of Gan materials in chargers has directly driven the great development of PD charger industry. Major manufacturers have also launched their own Gan chargers. In the face of these colorful chargers, are you at a loss and don't know how to start. In particular, many chargers often have multiple power versions, such as 18W, 22W, 30W, 45W, 65W, 87W, 100W and so on. Different power corresponds to different equipment. 18w-22w is mainly for mobile phones, 30w-45w is mainly for tablets / switches, and 65W is mainly for laptops, but they are also downward compatible.
In addition, in the same power, there are differences in interface specifications. Some are composed of one usb-c, others are composed of multiple usb-cs and usb-a, such as 2a1c, 2c1a, 3c1a and so on. Today, we will talk about how to choose suitable Gan Gan Gan chargers with the help of two different types of 65W PD chargers of Greenlink.
2、 Appearance design of green link Gan Gan 65W PD charger
I first used lvlian 65W PD charger with single usb-c interface. Later, I found that lvlian updated a 3c1a version, and the price was only 20 yuan, so I started with it later.
There are obvious differences in volume and weight between the two versions, 1c version weighs 120g, 3c1a version weighs 172g. I think there is still room for improvement in the volume control of the 1C version.
The charger adopts a similar mesh texture on the front. The front is a classic logo of "ugreen". The recognition of the product is still very high. The charging interface is located at the top. It can be seen that the 3c1a version is relatively compact, while the 1C version is somewhat loose.
Both versions of the charger use a folding pin design, which is easy to store and can avoid the abrasion of the plug. At the same time, the protocol specification of the charger is printed on the side of the pin. We will talk about it later.
