Some time ago, considering the needs of business trip and online office, I bought a laptop for my work. The lightweight book not only provides lightweight attributes, but also retains the full functional experience of PC, compared with the tablet + keyboard office solution, its advantages can be said to be very obvious.

However, after a few weeks of use, the small shortcomings of the lightweight book itself were also exposed. For example, the experience of keyboard and trackpad is not good, and there are too few interfaces. After connecting to the mouse, keyboard and other devices, if you want to connect other peripherals, the interface that comes with the lightweight book is somewhat stretched.

There is no doubt that the preferred solution for interface expansion is to expand the dock. After some selection, I got this Green Federation's 9-in-1 multi-port dock. There are two core reasons to start with this product: first, good sales and more positive comments; second, sufficient interface, which can effectively solve the "interface anxiety" of this thin book. Next, let's talk about the experience of using this product.

Let's start with the interface. This expansion dock has nine interfaces, including three commonly used USB-An interfaces, and another HDMI interface (supporting 4K@30Hz display) and VGA interface (supporting 1080P@60Hz display), which can be used to connect projectors, monitors and other devices, which is a must for office workers. The other three interfaces are SD card reading slot, TF card reading slot, gigabit network port and USB-C-shaped PD charging port. An expansion dock solves the needs of data reading, peripheral connection, wired Internet access, fast charging, and so on. Coupled with the compact and portable shape, it is very convenient for business trips or daily commutes.

Besides, appearance and workmanship. The overall texture of this expansion dock is relatively online, with silver-gray spray paint on the surface, a little frosted texture, and a delicate feel. The distance between interfaces is also reasonable, and there will be no "fighting" when connecting multiple devices. The shell is made of aluminum alloy, and the aluminum shell will play a more obvious heat conduction effect when the product is used, which is conducive to the heat dissipation of the internal chip, so the dock will feel a little warm, and it also belongs to the normal category. However, the daily use of keyboard and mouse, or plug in U disk to transfer small files, basically will not warm up.

There is another important reason, which has become an opportunity for me to get this expansion dock, that is, the stability of use. When a dock is not purchased, devices such as a wireless mouse or Bluetooth headset are used directly on the computer, and there are times when the device is connected abnormally, such as increased mouse delay, disconnection of the headset, and so on. often this situation will still occur after rebooting the computer. It is understood that this situation is caused by the interference of the equipment from the external signal.

Whether it is Bluetooth devices, 2.4G wireless devices or other electronic devices with the ability to send and receive signals, many of them work in the 2.4GHz signal band. However, the carrying capacity of the same frequency band is limited. Devices with relatively weak signal strength, such as wireless keyboard and Bluetooth headset, are easily disturbed by external signals, resulting in the equipment can not be used normally and stably. And what does this have to do with the dock? Of course there is. The Green Union 9-in-1 expansion dock I got added a design called "omni-directional shield", which is the key to solve the problem that the equipment is disturbed by external signals.

Through the disassembly diagram searched, we can see that the omni-directional shield wraps the PCB board to eliminate the interference of external signals. In this way, the wireless devices and Bluetooth devices connected to the extension dock can be used stably. According to the actual measurement, even if the extension dock is connected to devices such as wireless mouse and Bluetooth headset at the same time, all the devices can be used stably without interference. From a personal point of view, compared with the cool appearance and lighting effects of other dock products, a humble but critical design such as a shield is more worthy of attention.

On the whole, this is a product with solid workmanship, rich interfaces and outstanding performance in terms of stability in use. For a large number of frivolous books with fewer interfaces, the office originally said that this is also one of the best solutions to solve the "interface anxiety". Friends who need to expand the dock should pay attention to it.
