What is it, types, uses, advantages

What a USB dongle offers is the ability to connect it to your computer and give it a kind of connectivity that it does not have, such as Bluetooth or WiFi to a specific device. It is useful to use it on old computers that you want to reuse and do not have WiFi, for example. Or to give Bluetooth connection to your TV or your computer and connect controllers of consoles or portable and wireless keyboards that you have at home.

There are several types and it is one of the most comfortable devices that we can have if we want to reuse an old computer or simply if we have mounted our computer without taking this into account. Whatever it is, we review what it is, what types are there or which ones you can buy

What is a USB dongle?

As we have explained in previous paragraphs, it is a physical device similar to a pendrive or USB key that connects to the port of the laptop, desktop or television and that is capable of giving you a type of connectivity that it does not have. It is not a pendrive as such with which we can transfer files but it has the possibility of connecting our computer with Bluetooth, with WiFi or ANT + to connect it to certain types of sensors such as heart rate monitors or speed sensors.

It will depend on the model and what we need. They are usually affordable and very small in some cases and you just have to plug them into your computer’s USB port and configure them. They are not as frequent today as they were years ago because most of the devices that surround us already include all kinds of technologies such as Bluetooth, WiFi, GPS, etc.

What types of USB dongle are there?

The most common are for Bluetooth and for WiFi But there are also ANT + receivers that allow us to synchronize our watch or activity bracelet with a computer if we want to transfer the training data. There are also some that work as security USB to protect the device from unauthorized access or there are those that allow us have GPS technology on the computer although they tend to be less than others. But, usually, the two most useful and necessary are the Bluetooth and the WiFi connection. If your laptop does not have Bluetooth, a USB dongle is a key element to be able to use your headphones, your wireless keyboard or any other device that you can think of.

Bluetooth Dongle

Bluetooth technology is useful to transfer files between two devices quickly and we do it with mobiles before WhatsApp, Dropbox or Google Drive arrived. But it can also be really practical if you have a computer without a Bluetooth connection and you have bought a new wireless keyboard. Usually the mice you buy carry the USB plug-in in a dongle format but this is not the case with other devices such as keyboards or headphones or any other gadget that you want to connect. A Bluetooth USB dongle will only cost you about ten or eleven euros at Amazon and they are designed so that you can transmit whatever you want.

Another of the recommended delusions is that you use it for the car: if your car has a USB connection the safest thing is that it also has Bluetooth but if you cannot use this type of tiny device to connect it and thus send the music from your mobile phone without having to download it physically or put it on a CD. It is very useful and we can also use it on televisions if we want them to have Bluetooth, etc. It can save us on many occasions and we will only have to make sure that the operating system that we are going to use is compatible with that of the purchased USB device.

WiFi Dongle

Another of the most recommended and frequent uses is that of WiFi through a USB dongle that allows us to provide a wireless connection to a computer that does not have it or to any other device that does not have it. If you need to connect wirelessly instead of cable, you can have this USB that will save us installing an internal WiFi card in the computer case. Just plug in the USB to the corresponding port, it takes up little space and automatically, once you configure it, it will be able to detect nearby networks and you will be able to connect without difficulty.

In the case of Wi-Fi, we should normally look at more things, when buying one, than if you are going to buy a Bluetooth double USB. Usually we will look first at the nomenclature of the WiFi standard but also at the band in which it works because some will find that they work in both bands. Others, only in 2.4 GHz that offer us slower connections but with greater coverage.

We must also have consider if it is USB 2.0 or USB 3.0 but you should look at the device you are connecting it to and as long as it is compatible with a higher model. Other important aspects are security to see what it allows us and as long as they are, at least, compatible with WPA. Beyond this you can look at the size, whether or not they are tiny and easy to carry, but there are also some with antennas or without an antenna, etc.

USB Dongle


As we can see, there are many advantages that having a USB dongle offers us but we review some of the most important if you are thinking of buying one:

  • It is cheap, barely exceed 15 or 20 euros making it a solution suitable for any pocket.
  • Easy to install because just plug it in and sometimes configure it.
  • It is universal because any computer has USB port but also many televisions, many cars or any other device you want.
  • Comfortable to travel or to get you out of trouble.
  • We can connect whatever we want: a printer, a telephone, keyboards, mice, headphones, a portable speaker without the need for cables …
