USB HUB is a USB port expansion for multi-USB port devices. There are various USB HUBs on the market. In addition to the differences in appearance and jacks, these HUBs also have some functional differences. How to choose a better one? USB HUB with power supply?
When choosing a USB HUB with power supply, you can consider the following aspects:
1. Understand the types of USB HUB
First of all, it is clear that the USB HUB with power supply is an active HUB. This type of HUB is equipped with an external power supply and has more sufficient power supply. It can connect multiple mobile hard disks and other high-power-consuming devices. Compared with passive HUB (that is, HUB without external power supply), active HUB has significant advantages in stability and power supply capacity.
2. Consider power supply needs
Power adapter specifications: Active HUB is usually equipped with a 5V or 12V power adapter. The 12V power adapter provides more sufficient power and is suitable for connecting multiple high-power-consuming devices. The 5V power adapter is suitable for connecting some low-power USB devices.
Independent power supply interface: Some high-end active HUBs also provide independent power supply interfaces, allowing users to provide additional power support for specific devices to meet the power supply needs of different devices.
3. Pay attention to the number and type of interfaces
Number of interfaces: Select the appropriate number of interfaces according to actual needs. If you need to connect multiple devices, you can choose a HUB with a larger number of interfaces.
Interface type: Pay attention to whether the HUB supports USB 3.0 or higher interfaces, because USB 3.0 and higher interfaces have higher transmission speeds and better compatibility.
4. Check product performance and stability
Chip quality: High-quality chips are the key to ensuring the performance and stability of USB HUB. You can pay attention to the chip model and brand mentioned in the product introduction.
Heat dissipation design: Using USB HUB for a long time may cause heating problems, so heat dissipation design is also one of the factors that needs to be considered. Choosing a HUB with good heat dissipation design can extend the service life and improve stability.
5. Refer to user reviews and brand reputation
User reviews: Check other users’ reviews and usage experiences to understand the product’s advantages, disadvantages and scope of application.
Brand reputation: Choose products from well-known brands. These brands usually have better quality control and after-sales service.
