There are many digital devices around, almost all of which are charged with universal USB interfaces. Mobile phones, tablets, USB desktop fans, LED lights, Bluetooth headsets, sports bracelets, mobile power supplies, game consoles, etc., slowly find that USB interfaces seem to be insufficient, and frequent alternate plugging and unplugging makes the data cable damage faster. One product just meets my needs. It is a charging station product launched by Qingmi Technology a few days ago. It is a multi port USB power adapter with many bright spots.

Qingmi Technology is the manufacturer of Xiaomi's plug-in board, USB data cable and other products in the ecological chain. It has launched Xiaomi 3-port USB plug-in board, Qingmi intelligent plug-in board, vehicle inverter power and other products.

The outer package is simple and plain, with the consistent style of Xiaomi. A grey blue rice logo is printed in the middle of the front, and product parameter information and relevant information of blue rice technology are printed on the back. There is partition inside the box to separate the adapter body and accessories.

Qingmi charging station is a five port USB charging adapter, equipped with QC2.0 fast charging, rated output power of 65W MAX, and output modes of 5V/2A, 9V/1.8A, 12V/1.5A, 20V/1.5A. The biggest highlight is that the charging station can supply power to the notebook.

Qingmi charging station has complete accessories. In addition to the power adapter body, it also has Qingmi dual U laptop adapter, power cord, U-shaped bracket, thread transfer head, fabric storage bag and product manual.

The standard voltage/current of most notebooks is about 19V/3A, and the single interface of Qingmi charging station is 20V/1.5A. The parallel connection method can indeed increase the current, and the output terminal can reach 20V/3A. This reminds me of the old style mobile hard disk. Due to the lack of power supply from the USB socket of the computer, there was a strike from time to time. Later, I directly DIY a dual port data cable, cut the other USB cable, and connected the four cables in parallel to a complete USB data cable. After that, the mobile hard disk can also be used normally, which also makes my goose sister want to apply what I have learned.

Considering the different interfaces of laptops on the market, Tsingmi Technology provides six common adapters, five DC round adapters, and the popular ThinkPad square adapter, covering the charging interfaces of most computers on the market, which can basically be applied to mainstream models of laptops, but Apple laptops and Samsung notebook series that need ID protocol cannot be matched at present.

The power line of the charging station is a splayed tail power line in yellow and gray color, and the other end is a two end plug with an input voltage of 100-240V. It supports the global wide grid and can be used normally when traveling abroad. The power cord is a PVC wire provided by Volex, which is about half a meter long, and is placed on the desktop, suitable for placing near the power socket.

The two U-shaped supports can stand up when they are stuck on one side of the charging station. The two U-shaped supports are slightly loose when they are stuck in the middle. The two U-shaped supports are just tight when they are stuck on both sides of the head and tail. The charging station will not fall down when it is moved.

There are many accessories in the charging station, which is really inconvenient to carry. The cloth storage bag is also a more considerate reflection. When fully deployed, it is twice the size of the charging station. The seal is tied by a rope, and a small plastic block is fixed at the end of the rope, with the logo of Qingmi Technology on it. There is also a small partition inside the storage bag, which can be put into the charging station and then put other lines into it to distinguish.

Qingmi charging station is actually a multi port USB power adapter, which is made of flame retardant polycarbonate material and is 110 * 81018.3mm in size. The overall appearance is very simple. Except for the relevant parameters and certification marks at the bottom, there is no marking information on other surfaces. From the side, it is not difficult to find that the adapter is very thin and portable.

The USB panel adopts light gray color, and the output supports 5V/2A, 9V/1.8A, 12V/1.5A, 20V/1.5A voltage and current. The five way USB output adopts independent separation design, and can achieve QC2.0 output when used at the same time. It supports rapid charging of five mobile phones at the same time, and also supports simultaneous charging of laptops and mobile phones. If the total power exceeds the rated power, the system will automatically allocate charging power according to the equipment.

If the Qingmi charging station works with super power for a long time, it is not difficult to find that the body temperature rises relatively quickly. Try to power up my old notebook Lenovo Y450, and the temperature rises sharply. After 10 minutes, the measured temperature is about 46.7 degrees Celsius, and there is a slight burning sensation when you touch it with your hands. It is now the autumn of October, and the daytime room temperature in Guangzhou is around 30 degrees. It is inevitable that the fuselage temperature will soar. It is recommended to use it in an air-conditioned room or ventilated environment.

Qingmi charging station is small, light and thin, which is very convenient for travel. One power adapter can solve the problem of laptop and mobile phone charging at the same time, eliminating the different charging adapters of many digital products such as mobile phones and tablets. The most important thing is that you don't need to take the big piece of laptop charger to travel any more. It is such a novel and humanized design, It brings us electronic device enthusiasts fresh and interesting experience.

Finally, the advantages and disadvantages of Qingmi multi port USB power adapter are summarized.

1. Small size, light and thin;

2. It can charge both the mobile phone and the notebook;

3. Complete accessories and user-friendly design.
