SD/TF interface:
It is mainly to read the camera SD card/driving recorder TF card. The mainstream transmission speed of the docking station equipment is generally SD 3.0 version, and the transmission speed is 80MB/s; the high-end part is SD 4.0, and the transmission speed is 300MB/s;
USB interface:
USB3.0: (also known as USB3.1Gen1, USB 3.2 Gen1): 5Gbps (625MB/s), support 4.5W power supply;
USB3.1: (also known as USB3.1Gen2, USB 3.2 Gen2x1): 10Gbps (900MB/s), support 100W power supply;
USB3.2: (also known as USB 3.2 Gen 2x2): 20Gbps, support 100W power supply;
USB4: The maximum transmission rate is 40Gbps (5000MB/s) and supports 100W power supply.
At present, the USB interface on the market is mainly USB 3.0, up to the USB4 version.
DP interface:
DP1.4, bandwidth 32.4Gbps, supports 8K 60Hz, 4K 120Hz;
DP2.1, bandwidth 80Gbps, support 16K 60Hz, 8K 120Hz;
PD fast charging interface:
PD is the current mainstream standard fast charging protocol. The maximum power supported by USB-C is 15W (5V/3A) by default. If it supports PD 3.0 protocol, it can reach 100W (20V/5A), and the latest PD 3.1 can reach 240W;
5. Network connection: If your environment does not have Wi-Fi signal coverage, the docking station can provide a wired network interface (Ethernet port) to connect your laptop to the network.
Product features
The speed has no attenuation. Due to the use of hardware protocol conversion, after the pci device is connected to the notebook, the data of the pci bus has no attenuation and delay. Different models of docking stations can be plugged in half-length card and full-length card, half-height card and full-height card, 32-bit pci card, 64-bit pci card, and pci-x. Cards, different types of docking stations can be plugged in 1, 2, 4, 6, 7 or even 13 pci cards.
It is small and easy to carry. All-aluminum shell, good heat dissipation and light weight. Suitable for office workers.
What is wireless charging?
Wireless charging technology is a wireless charging technology that uses the principle of electromagnetic induction to charge the device by transmitting electrical energy. It avoids the trouble of traditional wired charging that requires plugs, making the charging process more convenient, beautiful and efficient. Wireless charging technology is widely used, including smartphones, tablets, headphones, smart watches and other portable electronic devices. Wireless charging technology works by transferring energy through a magnetic field between the charger and the receiver. The charger generates a magnetic field. When the receiver is placed in the magnetic field, it generates an eddy current, which generates another smaller magnetic field. Due to the principle of electromagnetic induction, this smaller magnetic field will generate a voltage in the charger to realize the transmission of electrical energy.
There are many ways to realize wireless charging technology, such as magnetic induction charging, magnetic resonance charging, radio wave charging, etc. Among them, magnetic induction charging is the most common wireless charging technology. It uses a magnetic field to transmit energy, with higher energy transmission efficiency and lower cost. Magnetic resonance charging uses magnetic field and capacitance coupling to achieve wireless charging, with higher charging power and smaller volume. Radio wave charging transmits energy to the receiver through radio waves, but it requires more complex circuit design and higher cost.
The advantage of wireless charging technology lies not only in its convenience, but also in its efficiency. Compared with traditional wired charging, wireless charging can avoid wear and tear caused by plugging in the charger, and also reduce potential safety hazards caused by loose charging cables. In addition, wireless charging technology can provide a more beautiful charging experience without worrying about the winding of charging cables and messy wires, making charging more convenient and fast.
Although wireless charging technology has been widely used in recent years, there are also some limitations. For example, there is still a certain gap between the transmission efficiency and charging speed of wireless charging compared with wired charging, and the cost of wireless charging devices is relatively high. Therefore, in future development, the transmission efficiency and cost reduction of wireless charging technology need to be further improved in order to be more widely used in various devices.
Use
The notebook docking station is an external device that can provide more interfaces and functions to expand the ability of laptops. The following are some common uses:
1. Extended connection interface: Many modern laptops have only a few USB ports, HDMI interfaces, etc., while the docking station can provide more interfaces, allowing you to connect more external devices at the same time, such as mice, keyboards, printers, monitors, etc.
2. Multi-screen support: Some advanced docking stations support connecting laptops to additional monitors. In this way, you can work on the main display and consult information or perform other tasks on the auxiliary display.
3. Data transmission speed enhancement: Some docking stations are also equipped with high-speed USB 3.0 or Thunderbolt 3 interfaces, which can provide faster data transmission speed. This is particularly useful for users who need to frequently copy large files or process a large amount of data.
4. Charging function: Some types of docking stations also have charging function, which allows you to charge multiple devices at the same time (such as mobile phones, tablets, etc.) through a hub, which is convenient and space-saving.
