Many times, we are faced with the dilemma of not being able to connect multiple devices at the same time due to the limited number of USB ports on our computers, which is really annoying. But fortunately, USB hubs provide us with a solution. This article will take a deep dive into the knowledge of USB hubs, including their types, functions, features, and considerations when purchasing.
What is a USB hub?
USB hubs are essential devices in modern technology. They can expand the number of USB ports on computers, smartphones, tablets, and game consoles. With USB hubs, users can plug multiple USB devices into one port and enjoy the convenience of multi-port connection. Although multiple device connections may slightly increase latency, the difference is usually imperceptible.
Types of USB hubs
USB hubs are mainly divided into two types: active and passive:
Active USB hubs
Active USB hubs are usually connected to the mains power supply and equipped with a built-in AC adapter to power the plugged-in external devices. They are suitable for connecting high-voltage devices such as printers, scanners, and external hard drives. They are particularly useful in the workplace, but the price is relatively high. Also, since it needs to be plugged into a power outlet, make sure there is a power source nearby when using it.
A passive USB hub does not require an external power source and relies on the computer or device it is connected to for power. Therefore, it is suitable for devices with lower voltage requirements, such as smartphones, keyboards, flash drives, and game controllers. Passive USB hubs are more affordable and convenient for travel or when power is not available.
Benefits of USB Hubs
USB hubs provide many benefits whether they are powered or not:
Improved data sharing: Easily connect multiple devices and transfer data.
Improved workstation: Professionals such as creators and musicians who need to work with a large number of devices can connect all their devices through a USB hub.
Easy gaming: Provides additional ports for gaming laptops to connect gaming keyboards, headphones, and other devices.
Convenient data storage: Allows multiple storage devices to be connected at the same time without frequent plugging and unplugging.
How to use a USB hub
Using a USB hub is very simple. For a powered USB hub, plug in the AC adapter first, then connect to the computer via a USB cable. Once the device is plugged into the hub's USB port, the computer will automatically recognize it and be ready for use.
Buying Tips
When buying a USB hub, make sure it matches the type of ports on your computer. Also, buy from a reputable tech gadget store, such as Anker's website, to enjoy the warranty and customer service.
In short, USB hubs are ideal for expanding the number of USB ports on your computer. Understanding the different types of hubs and their functions will help you make an informed purchasing decision.
