With the continuous maturity of gallium nitride technology and the promotion and popularization of gallium nitride chargers, charging plug-ins have also ushered in a new generation of gallium nitride plug-ins. Thanks to the material characteristics of gallium nitride, compared with traditional plug-ins, gallium nitride charging plug-ins have a smaller volume and higher power. Currently, the author uses a Rubik's Cube converter on his desktop. Although it is not large in size and has 3 U ports, the maximum output power is only more than ten watts, which is basically difficult to meet the current fast charging needs of electronic devices. Therefore, the U port is basically in a semi-idle state, and the Rubik's Cube plug-in is also filled with various chargers.

Recently, Bisi has launched a new gallium nitride fast charging plug-in line, with multiple interfaces of 2U+2C, and supports up to 65W power output and supports multiple fast charging protocols. Because I have been exposed to BeSi's power supply products before, I am quite confident about BeSi's quality, so I decided to take advantage of this GaN3 Pro desktop plug-in board. Whether the desktop charger can be terminated this time depends on it.

I saw the promotional picture of this product online before and thought it would be quite large. However, after unboxing, this plug-in board is much smaller than I expected and can be easily held with one hand.

plug-in board is a small rectangle with a square cross-section. The MAX 2500W logo is printed on the upper left corner of the front, indicating that the total power of this plug-in board is 2500W, and the small volume and large energy are the best interpretation of it. The four edges are all designed with large rounded corners, and you can't hold them and don't cut your hands. If you need to carry them out, you don't have to worry about scratching other items.

times SiGaN3 Pro plug-in board wire material is very sufficient, the wire core adopts a size of 1mm², and the outer diameter of the wire is relatively thick, which is in sharp contrast to the compact size of the plug-in board. Some people may think that the material is too useless, but this is not the case. This plug-in board supports up to 2500W of total power, Type-C single port supports up to 65W output, and USB single port supports up to 60W. Using thicker wire cores can further reduce heat generation and have a higher safety factor.

plug-in board length is about 1.5m, with sufficient length and easy to connect to power. The plug is a 10A high current plug, and fingertip grooves are carefully installed on both sides, making it easier to plug and unplug.

In addition to this set of plug-in boards, Beisi GaN3 Pro is also equipped with a C to C data cable about 1m long, which can be used for fast charging output of Type-C port. Don’t underestimate this data cable. From the end position, you can see that this charging cable supports up to 100W fast charging and can be used for fast charging of most devices, including laptop .

biSiGaN3 Pro plug-in board is a 5-hole socket design that can meet the electricity needs of daily equipment. The jack has a built-in 75N safety protection door to prevent children from touching their fingers from causing electric shock. This design is quite considerate. If there is an additional set of holes on the front, it may be more widely used.

charging ports are distributed on the end surface of the plug-in board. The top two are Type-C interfaces, and the bottom two are USB ports. Friends with sharp eyes will soon find that the color of the socket is different. In order to distinguish the fast charging port from the ordinary port, Beisi designed the fast charging port to orange, which is clear at a glance. A light blue indicator light is provided above the interface, which can be used to determine whether the plug-in board is currently powered on.

Both Type-C interfaces support 65W fast charging output, which can quickly charge laptops, mobile phones and other devices. For example, the Redmibook14 I currently use currently supports up to 65W fast charging, iPhone12 is 20W, and Xiaomi 9 has a maximum of 27W, which can basically meet the fast charging needs. When using a single port with a PD fast charging cable, the iPhone 12 can be charged 46% in 30 minutes, and the Xiaomi 9 can be charged 64%.

black USB interface is a standard charging interface, supporting up to 5W power output, suitable for charging bracelets, watches, Bluetooth headsets and other small-power devices. The orange U port supports up to 60W fast charging output, which can basically meet the fast charging needs of most electronic devices at present. When using the U2 port output, the iPhone 12 can be charged 42% in 30 minutes and Xiaomi 9 can be charged 62%, both of which are within the normal range.

and above are all single-port output tests, but in actual life, multiple ports are generally used at the same time. When the number of access devices is different, the output power of each interface is also different. The official gives the power output by each interface when using different interfaces.

As can be seen from the figure, the Type-C1 port and the USB1 port should each occupy independent channels, and the Type-C2 port and the USB2 port should share a fast charging channel. Therefore, when the Type-C2 port and the USB2 port are put into use at the same time, the output power will be greatly reduced, with a maximum of only 15W. When used in combination, the Type-C1 port will drop to 45W, while the USB1 port will remain unchanged by 5W.

is tested according to the author's normal usage mode. When the Type-C1 port is connected to a 65W laptop, the Type-C2 port or USB2 port is charged, the data performance is basically the same as the above-mentioned single port output. When the Type-C2 port and USB2 are connected to two devices at the same time, the power will be significantly reduced. The details are as follows. From this, it can be seen that the Type-C2 port charges relatively faster when connected at the same time.

Therefore, when I use it normally, the Type-C1 port is often used to connect to laptops. The Type-C2 port and USB2 port are used to charge mobile phones, power banks and other devices. The USB1 port is a low-power interface, which generally charges watches, headphones, etc.

Thanks to the material characteristics of gallium nitride, when charging multiple devices at the same time, the surface of the plug-in board is still in a warm state, and the heating area is mainly concentrated in 1/3 of the plug-in board. The Besi GaN3 Pro shell uses 750℃ flame retardant material , which has passed the national 3C certification and is safe and secure.

For daily use, this gallium nitride charging plug can indeed replace most charging plugs, and in terms of the size of the plug-in board, it does not take up much space on the desktop. When multiple interfaces are used simultaneously, the output power can also meet the fast charging needs of most devices. The wire part has a larger proportion than the overall size, so the portability is relatively poor. There are fewer plug holes, only one set, if you want to use some other equipment, you need to use other plug-ins.
