When it comes to modern laptops, they have improved on nearly every single thing that older laptops have done. That said, with fast progress, there comes a problem where other types of devices are not quite ready and that leads to compatibility issues.

In this case, we’re talking about how most laptops these days have many USB-C ports, but they’re missing USB 3.0 ports. Most laptops now have few USB 3.0 ports and that leads to having trouble connecting the devices that you want to your laptop. Not all external devices are compatible to use with USB-C, and most of the time using a USB 3.0 port is convenient.

That’s why in this review we’re taking a look at this Alxum 4-port USB 3.0 port Hub. This is likely one of the simplest USB port hubs that you can find, and that’s completely fine because it solves a simple issue and it’s very effective at doing so.

An abundance of USB 3.0 Ports

There are a total of four USB 3.0 post on this Alxum hub, and the uses a USB 3.0 cable that you use to connect to your laptop. So to connect this to your laptop, or your computer, you must have at least one USB port available.

The expansion of four USB 3.0 ports is useful and we highly recommend this Alxum hub as each of the four ports allows you to connect smartphones, tablets, flash drives, and any other devices that you would be able to connect directly to your laptop or computer. In our case, we connected two smartphones and two flash drives to the Alxum hub. We were able to easily access files on a Lenovo Flex 5 laptop, as easily as we would be able to access them as if they were directly plugged into the laptop itself.

There is also a Micro-USB port on this hub, and you may find a use for it if you want to connect higher powered devices such as an External Hard Drive.

Size and Design

The size of this Alxum hub is very small, the hub has a length of 4.2 inches, a width of 1.2 inches, and a thickness of 0.4 inches. It won’t be taking up much space at all, and the better part is that the hub’s cable is 4 feet long so you’re not restricted on where you want to place the hub.

When it comes to using the hub, it’s simple, as you only have to plug it into a USB port on your computer or laptop, and you’re ready to use it. There is a blue LED power light to show that it’s on, and all the ports can be found to the sides of the hub. The Micro-USB port is found right next to the cable.


We think that this Alxum hub provides base reliability when it comes to a USB hub. What we mean is that you won’t find any SD card, Power Delivery ports, HDMI, or VGA ports on this hub. You have the bare essentials of four USB 3.0 ports and a Micro-USB port, and that may be what most people need, as the USB 3.0 port is still the most used port for connectivity and sharing files.

If you’re looking for more things from a hub, then this is not the one.


This Alxum 4-Port USB 3.0 hub is simple and we think that is completely fine. Most of the time simple is the solution, and being able to connect four smartphones at the same time or connecting four USB flash drives at the same time to share files is exactly what this USB port hub is made for.
