There is nothing wrong with buying a USB hug considering how they have become a necessity for many rather than just a component that people used to buy because they are looking for ports. Nowadays, devices, especially laptops are limited to very few USB ports and that is a problem that people need to work on.
That being said, it is important that whenever you are buying a gaming USB hub or a simple one, you make sure that you know that the one you are looking for is a good one. You do not want to invest in something that is not even going to be useful for you in the long run.
USB 3.0 or Higher
USB 2.0 is a standard that is old, but for some reason, the cheaper options are still using this standard. If you really want to avoid that, you should always invest in a hub that offers USB 3.0 or higher. This way, you will not have to worry about getting slow transfer speeds or anything else that will be coming in the way.
Make Sure It is Low Profile
With the devices becoming slimmer, there is no point in buying a USB hub that is chunky. Especially if you plan on carrying it with you because you do need those ports. Now when you are doing that, you need to make sure that the hub you are getting is low profile.
The benefit of that will be the fact that you can easily tuck it in your backpack when the need arises, and once it is connected to your computer or laptop, you will not have to worry about something taking up a lot of space on your desk or in your bag.
