USB hubs

Currently manufactured stationary PCs and laptops are usually equipped with at least 2 USB A-type ports. Thanks to this, we can connect various external devices to the computer, such as a mouse, keyboard, flash disk, MP3 player, MIDI-to-USB interface, mobile phone and many more. The problem appears when we want to connect many devices to the computer at the same time - then there are no free USB connectors. In such a situation, for example, we must stop charging the battery in our portable MP3 player to be able to use the wireless mouse. However, there is a simple solution to this problem, which is to connect a USB hub to the computer. Thanks to this device, the problems related to the parallel use of several USB devices at the same time disappear. Our offer includes USB hubs diversified in terms of practical additional functions, such as switches for individual USB ports, LED backlight, and micro SD memory card readers. In terms of power supply, the Botland store offers USB hubs powered directly from the computer's USB port, as well as active USB hubs that require an external AC adapter. Unlike passive USB hubs, active USB hubs provide very high power efficiency. The USB hubs available in our offer are compatible with the USB 2.0 and USB 3.0 standards.

USB hub - the easiest way to increase the possibilities of computer cooperation with external hardware

Similarly to a power strip, it allows you to power several electrical devices from a single AC 230V electric socket, on the same principle, a USB hub allows you to connect several devices to a computer using its single USB port. Depending on the model, the number of USB ports in a single hub ranges from 3 to 7, while the data throughput is determined by the supported USB standard, ie USB 2.0 or USB 3.0. The USB hub is not only increasing the possibility of parallel operation of many devices at the same time, but also facilitating access to them. You can place the USB hub on your desk and thus you will not have to constantly disconnect and connect devices to the USB ports in the computer's central unit, which is located with a connector plate to the wall or if access to it is otherwise difficult.

USB hub - how it works

The USB hub works immediately when plugged into a USB port. The USB hub allows you to extend the basic possibilities of cooperation between the computer and external equipment and facilitates the use of the computer. There are three types of USB hubs. The first is a passive USB hub. It is the simplest and cheapest construction. Such a USB hub is powered with + 5V voltage directly from the computer USB port and does not have an external power supply, therefore it cannot be used to power devices with increased power demand, such as external HDD drives. The second type is an active USB hub, which is equipped with an independent power source - the AC adapter. Unlike a passive USB hub, an active USB hub is larger, costs a little more and takes up more space, but usually has more USB ports and, due to its independent power supply, allows you to connect and operate more USB devices, including those with high current draw. There is also a mixed design that includes the features of a passive and active USB hub. Such a USB hub can function with the use of power from the USB port of the computer, but also with its independent power supply.

What should you consider when buying a USB hub?

USB hubs can not only be divided in terms of the basic type of design (passive vs active vs hybrid), but also in terms of other parameters that can play a key role when buying. Among the important factors, it is also worth considering the type of supported plugs. Usually, USB hubs can support USB A-type plugs in the USB 2.0 data transmission standard, and more expensive models can support USB C-type plugs, in a higher data transmission standard - USB 3.0. The type of plugs should be selected following the cooperating devices and their number. The hub can also be equipped with additional connectors, such as a reader for SD and micro SD memory cards, an RJ45 connector for wired data transmission in the Ethernet network, as well as micro USB B-type connectors and a headphone jack.
