Simple Converter to multi-functional Docking station -5

In addition to the mainstream multi-screen extensions, there is necessarily more than that.

SD interface: essential for photography players

Speaking of SD / TF cards, this is also a memory of an era, early laptops also have such interfaces, but with the emphasis on the principle of overall integrity, they gradually disappeared in the history of notebook interfaces.

 But for photography users, the SD interface is indispensable. SD card slot is divided into standard SD card slot and Micro SD card slot, corresponding to standard SD card and Micro SD card;

And most of the current notebook with SD card slot interface for UHS-I interface, there are faster UHS-II on the market, transmission speed is greater, but support UHS-II SD card price is also relatively high. For docking stations, if not special requirements, the transmission speed of 80 MB/s is enough.

 Gigabit network port: game players do not drop the line

 Although the speed and stability of wireless network has been little different from the wired connection, for the game players who attach great importance to the network Ping value, a little network fluctuation may determine the outcome, so it is also a must for users with high network speed and stability requirements.

At present, the mainstream docking station is the RJ 45 Gigabit network port, which can adapt to 10Mbps, 100Mbps and 1000Mbps bandwidth.

3.5mm audio port: The memory of The Times is echoing

 Since the release of iPhone 7 in 2016,3.5mm has gradually become a memory of an era. Although people still like to call it "several advanced 3.5mm ports", but it has actually become a thing of the past.

But for the 3.5mm audio port, it is still an indispensable part of the current desktop host, used to connect wired headphones, audio, microphone and other sound devices, compared to wireless, the connection is more convenient, universal and stable.

 PD fast charge: more efficient endurance

 As the charging protocol of USB Association, PD has been developed in three versions, PD / PD2.0 / PD3.0, among which PD2.0 and PD3.0 are the most common. PD provides various types of power supply specifications according to different electricity consumption, so it supports a variety of devices, from mobile phones to tablets to laptops.

PD 3.0 currently supports 5V3A, 9V3A, 12V3A, 15V3A and 20V5A output, with a maximum power of 100W, which basically meets the fast charging of some smart phones. However, with the development of fast charging in recent years, the era of 100 watt flash charging has arrived.

 The PD 3.1 standard is divided into the standard power range and the extended power range. Among them, the standard power range is the current mainstream USB PD3.0 PPS fast charging standard on the market, and the maximum charging power is still 100W unchanged;

 The newly added three voltages of 28V, 36V and 48V belong to the expanded power range. The maximum output current corresponding to the three voltages is 5A, and the power is corresponding to 140W, 180W and 240W. For mobile phones, the second charging era is within reach.

 But for the docking station, the PD100W is enough, charging enough for some lightweight laptops, and the higher 240W is still conservative for now, since there is a difference between laptops and phones.

 From this point of view, whether it is a splitter only focusing on USB interface expansion, or a multi-interface all-around expansion dock, the constantly upgraded interface speed and specifications are all designed to provide users with faster and more convenient office and entertainment experience.

 Users can choose products that are more in line with their own scenarios according to their own needs, so as to better unify economic efforts and efficiency output. Video high-definition, audio lossless, picture refinement, also greatly improve the transmission threshold of the cable device and docking station, "fast transmission" will be a constantly upgraded concept.

For the use of high-end scenarios, different industry level will bring higher requirements, such as Vcan Networking 12 and 1 docking station with high-speed transmission, screen expansion products will be more and more, more screen use scene will gradually from a scarce scene to daily, in order to open the new situation of "future vision".
