The difference between USB HUB and USB docking station
USB HUB, also known as a USB hub, refers to extending multiple USB interfaces from one USB interface.
USB docking station, also known as port replicator, refers to a device that expands other interfaces from the USB interface (such as audio input and output interfaces, video output interfaces, Bluetooth, COM or LPT interfaces, card readers, network cards, power adapters, printers, etc.) and many more interfaces). But this kind of thing is relatively rare, and the price is not cheap (hundreds or even thousands, which is equivalent to integrating various devices such as USB sound card, USB network card, USB external graphics card, card reader, USB HUB, etc.), and also Only after the emergence of USB3.0, there are a small number of products (USB2.0 is also available, but it is rarer, and there are more 2 USB card readers, Bluetooth and several additional USB interfaces, due to the bandwidth and bandwidth of USB2.0 Power supply is more of a problem). Therefore, the difference between them is that the USB docking station can expand other interfaces except USB, while the USB hub can only expand USB interfaces.
Frequently asked questions about USB HUB and USB docking station
The USB Hub expansion dock will generate heat, the difference is the degree of heat generation.
According to the test results of the previous Hengping, we have concluded a rule: the docking station with a small size (such as a five-in-one docking station) has a limited heat dissipation area, and the heat will be more serious, and the heat can reach more than 50 degrees; the volume The large (10-in-1 docking station) docking station has a large heat dissipation area, the heating temperature is generally lower, and the temperature is stable below 50 degrees.
The manufacturer of the expansion dock refers to the standard GB4943.1-2011 in terms of heat generation (the temperature of the metal material held for a short time should not exceed 60 degrees). From the results of our test, no matter the size, the heat generation of the expansion dock is average. Between 45 degrees and 55 degrees, they all meet this standard. If you are worried about the heating of the docking station, it is best to connect it directly with a cable. In addition, it is recommended not to charge the laptop through the type-c expansion dock, because first, it will increase heat generation, and second, it will increase the risk.
2. Wi-Fi, Bluetooth interference
The reason for the disconnection of Wi-Fi and Bluetooth is that the signal shielding of the docking station is not done well. This kind of problem mainly occurs on domestic docking stations of small and medium brands, because these docking stations basically do not do signal shielding. Take the best Apple converter made of signal shielding as an example. Apple wraps the PCB board of the converter with a metal shielding layer 360 degrees without dead ends, thus avoiding the problem of Wi-Fi and Bluetooth interference. Domestic small and medium-sized brands do not take signal shielding seriously, and basically do not take signal shielding measures, so Wi-Fi or Bluetooth disconnection is common during use.
3. Burn the motherboard
Judging from the exchanges on various websites, the problem of burning the motherboard basically involves charging the laptop through the USB expansion dock.
How to minimize the probability of burning the motherboard? First of all, we must avoid poor quality expansion docks, and secondly, we should not charge the laptop through the USB docking station. It is best to plug in directly for charging.
