In this issue, the editor will bring you what usbhub means. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

UBS HUB is called USB hub.

To put it simply, USB HUB is a device that can divide a USB port into many USB. It is usually used when the USB interface of the user's computer is not enough, and more USB devices can be connected outside.

USB HUB can be divided into USB2.0 HUB, USB3.0 HUB and USB3.1 HUB according to the USB protocol to which you belong. Of course, you need the USB support you receive.

USB HUB can be divided into power supply and no power supply:

HUB with power can support high-power USB devices, but not without power.

It is recommended to connect the external power supply, which is helpful to the stable operation of USB.

The maximum output current of the USB2.0 interface of the computer is 500mA, and the output voltage is 5V, which translates to the theoretical output power of each USB2.0 interface of the computer is 2500mW, and the splitter itself also has part of the loss, so when the output power of the USBhub splitter is greater than 2500mW, it needs an external power supply. The computer also has a USB3.0 interface, usually the output current is about 750mA, individual models can reach 1A, the output voltage is also 5V. Similarly, the external output power (according to the maximum) reaches 5W, if it exceeds it, it will be connected to the external power supply. In this case, whether USB2.0 or USB3.0 is used through the splitter, no matter how many interfaces there are, your input and usage will determine whether or not to connect the external power supply.

The commonly used USB high-power devices are:

Smartphone, USB stereo, USB fan, USB hand warmer, portable battery, mobile hard drive

The above is the meaning of the usbhub shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
