Mobile phone / Notebook Charger head / charger Selection Guide

With the iPhone 12 no longer free charging head, people's demand for additional charging head began to increase.

There are more and more electronic products in hand, such as laptops, mobile phones, e-books, game machines, etc. As most devices can support fast charging, if the traditional charging head is still used, not only the charging efficiency can not be improved, but also it is large and heavy, which can not meet the demand of charging multiple devices at the same time.

If you just buy a charging head for the iPhone 12, you can choose a smaller one. Single port, small size, easy to carry. It is recommended to choose Anker's pd20w, the top selling product of double 11 in 2020.


If you need to provide fast charging for multiple devices at the same time to meet the demand of notebook, mobile phone and other fast charging at the same time, it is recommended to choose gallium nitride charging head, which is small in size and high in charging power. Now many brands of mobile phone charger are also gallium nitride chargers, which can greatly reduce the size and weight of the charger while meeting the demand of device charging

For some mobile phones, there is a private fast charging protocol. In order to achieve fast charging, the mobile phone needs its own charger and data cable. Data line is also an important factor to realize fast charging. Ordinary data line can not realize fast charging because of its limited current.

Switch charger

The charger we are using now belongs to switch charger. The principle is as follows. Comparison of linear charger and switch charger

The ancient linear charger, the historical mobile phone, all use this charger, which is big and heavy, and the output voltage and current are very low.

With the switch charger, the charger starts to become smaller and more powerful.

Fast charging technology

Fast charging technology supported by different manufacturers

Different manufacturers, the charging protocol supported is different. As long as the charging head supports the corresponding fast charging protocol and matches the charging line, the mobile phone can support fast charging normally.

Gan Gan Gan charging head

Gan, known as gallium nitride in Chinese, is a new type of semiconductor material. It has the characteristics of large band gap width, high thermal conductivity, high temperature resistance, radiation resistance, acid alkali resistance, high strength and high hardness. It is widely used in new energy vehicles, rail transit, smart grid, semi conductor lighting and new generation mobile communication in the early stage, and is known as the third generation semiconductor material. With the technology breakthrough cost being controlled, Gan is widely used in consumer electronics and other fields, and charger is one of them. The charger with Gan components is characterized by high efficiency, low heating, large power but small volume.

The characteristics of gallium nitride charging are small volume, light weight and high power. Comparison of the size of gallium nitride and traditional charging


The general Gan charging head is selected, and multiple ports are selected as far as possible. The notebook, mobile phone and other devices can be charged simultaneously. Although charging at the same time, it can not realize the fast charging of all connected devices, but the total time of simultaneous charging can be saved.


Now, the cost of Gan chargers is still relatively high, notebook manufacturers have not given them at random. Xiaomi 11 has begun to give gallium nitride chargers. Apple has also entered the gallium nitride market. In the future, there should be more high-quality and low-cost Gan chargers.

Anker Anker 20W charging head

Anker is a well-known supplier of charging head, and it used to be an overseas market. And Apple's partner.

This charging head is a hot-selling product of Anker, which is the same volume as Apple's traditional five Fu An charging head, but it realizes 20W charging power. It uses Apple original chip to support all models after the iphone8. Support pd3.0, qc3.0, and can be used for quick charging of millet, Huawei, Samsung, oppo and other models.

100 million color 20W charging head

It supports 20W fast charging and iPhone 8 models, but it is not as good as Anke, which is a high cost-effective option.

Gallium bisitride


In 2019, Beth launched its first 2c+1a charging head, winning the 19-year double 11 championship. As the second generation 65W multi port Gan 2 Pro charger of Beisi, the appearance of the charger is designed by family ID. all the internal and external parts are redesigned. The compact volume is equipped with a new heat dissipation technology and bpsii charging technology, and the volume is further reduced. The volume is 5mm shorter than the previous generation. There are also Lite versions, 1c+1a, which are cheaper.

Small meter Gan charging head


It supports 65W maximum power, and can charge notebook, millet mobile phone, apple mobile phone, etc. in the package, there is also a 5A data line with a length of 1m and equipped with e-marker chip to ensure high-power fast charging.


Pins cannot be folded, only one C-Port.


Fast charging data line


Because fast charging requires a higher charging current, you need to choose a charging line that supports 5A or buy a suit of charging head and data line. It is best to select the data line with e-marker chip. Only the data line equipped with e-marker chip can support the current of more than 5A and realize the fast charging of more than 65W. That is, you can charge your laptop.


The notebook charging is a cable with double C port, mobile phone charging and A-port cable. Or choose a 3-in-one quick fill line.
