Although Apple MacBook prices have become more and more close to the people, but for most users is still relatively expensive, especially the MacBook interface is relatively small, user expansion has to buy additional accessories. After browsing Apple's official website, it is absolutely amazing. How much does it have a docking station including DP, Thunderbolt 3, USB3.0, headphone jack and network RJ-45 interface? More than RMB 2,800, no kidding, and no card reading yet. Device.
As a result, the third-party Audio & Vedio adapter became the top choice. Although there are too many expansion docks for Apple in the market, many users who have a mixed dock are unable to choose. After all, the price is tens of dollars, and the price is not worth it. Instead of being dilemma, it is better to choose the Kingston Nucleum USB-C Multi-Function Hub directly!
The STC USB-C multi-function hub is very compact, even if it contains data lines, it is only 276.4mm long, and the weight is only 92.4g, which is very convenient for carrying.
The hub is connected to the MacBook via a Thunderbolt 3 interface, and then provides up to 7 common interfaces, including 2 USB 3.1 type A interfaces, 1 USB 3.1 type-C interface, and a USB-C charging port ( Up to 60w), one HDMI (v1.4) interface supporting 4K output, one TF card slot (UHS-I) for one SD card slot (UHS-II).
1 lightning 3 interface with 7 devices, many people are worried about whether it will affect the speed, in fact, do not worry, because the speed of the lightning 3 interface can reach 40Gbps, and the theoretical speed of USB3.1 is only 10Gbps, the actual effective bandwidth is only 7.2Gbps In addition, the theory of HDMI (v1.4) is 10.2Gbps, so a lightning 3 interface with more than 7 expansion ports is more than enough. After all, there is no one who can simultaneously play 4K video with HDMI and then copy data with 3 USB3.1. SD and TF cards also transmit data at the same time.
I have to say that the market is currently filled with a lot of USB3.0 interface docking station, although UBS3.0 and USB3.1 seem to have little difference, the actual size of the specification is more than 1 times.
USB 3.0 is 8b/10b encoding, that is, for every 10 bits of data transmitted, only 8bit is the real data, and the remaining 2bit is used as the check code, so the entire bandwidth will have a loss of up to 20% (2/10); USB 3.1 uses 128b/132b encoding. In 132bit data, only 4bit is used as the check code, and the transmission loss rate is greatly reduced to 3% (4/132), so USB 3.1 is not only to increase the bandwidth, but even Transmission efficiency has also improved a lot.
In addition, USB3.0 provides a 5V/0.9A power supply, while USB3.1 provides a 20V/5A power supply with a maximum power supply of 100W. So, don't look at the same appearance of USB3.0 and USB3.1, there is only a little difference in the naming, in fact, the gap is very big. For example, copying a video, regardless of the hard disk factor, if USB3.0 takes 1 minute, USB 3.1 only takes 30 seconds.
PPT commercial demonstration HDMI is more calm
In the commercial field, PPT has become commonplace, and often requires external devices. The devices are generally divided into two categories. One is a traditional projector, which usually has a VGA or HDMI interface, and the other is a large-size TV with an HDMI interface. .
However, for the Apple MacBook, there is no video output interface. The VGA or HDMI of the lightning port is expensive and has a single function. Fortunately, the Kingston Nucleum USB-C Multi-Function Hub provides a 4K output HDMI (v1.4) interface. For most projectors or TVs, 4K resolution can provide the clearest picture at the moment. Stay at 720P or 1080P.
Of course, its biggest benefit is to save trouble. For business travellers, there are often keyboards, mice, and a small fan with a USB interface. In the past, these devices needed to be plugged into the computer, and now all peripherals are connected to the Kingston Nucleum USB-C. The function hub is then connected to the computer via its data cable. And, for the data line that is often plugged and unplugged, Kingston will also use the silicone package to interface, which greatly increases its toughness and ensures a longer life.
At present, the STC USB-C multi-function hub is priced at only RMB199 yuan, which is much cheaper than Apple's peripheral products. It also has Kingston's gold-plated signboard and 2-year warranty. Users can purchase and use it with confidence.
