Alxum 8-in-1 USB-C hub review

alxum 8 in one usbc hub 01

REVIEW – I truly miss having vital ports on my laptop, so I make do with USB-C hubs. Alxum has a few of these hubs, one of which is the 8-in-1 USB-C hub which I was able to review. It has eight ports: an Ethernet port, a VGA port, a USB-C data/100 W Power Delivery 3.0 port, an SD card slot, two USB 3.0 Type-A ports, an HDMI port, and a 3.5 mm audio jack. I was able to test all connections except for the VGA because I don’t have a VGA cable to connect our monitor to the hub (we use the HDMI connection instead). All worked well for me and I liked the flexibility of being able to use the USB-C port to transfer data or charge up to 100 W using the USB-C passthrough charging.

What is it?

The Alxum 8-in-1 USB-C hub is one of those necessary peripherals that allow you to connect eight external devices to your USB-C equipped laptop or tablet. It contains the following ports: Ethernet port, VGA port, USB-C data/100 W Power Delivery 3.0 passthrough charging port, SD card slot, two USB 3.0 (or USB 3.1 Gen 1 or USB 3.2 Gen 1) Type-A ports, HDMI port, and 3.5 mm audio jack.

Design and features

alxum 8 in one usbc hub 03The Alxum 8-in-1 USB-C hub has an outer aluminum housing and is fairly attractive as far as USB-C hubs go. This side of the hub shows (from left to right) the USB-C data/100 W Power Delivery (PD) 3.0, an SD card slot (microSD cards will need an adapter), two USB 3.0 (or USB 3.1 Gen 1 or USB 3.2 Gen 1) Type-A ports, and an HDMI port.  alxum 8 in one usbc hub 06The bottom of the hub has labels for each of the ports.

One end of the hub has a VGA port and an Ethernet port with LEDs, while the other end of the hub has a 3.5 mm audio jack.

Performance

I was able to use all of the ports simultaneously (with nothing connected to the VGA port). I connected my Lenovo Yoga 730 13″ laptop to my LG TV using the HDMI port (see “Note” below), I opened a photo on my SD card, I opened a Word document file on one of my USB-A flash drives, I played a video from another USB-A flash drive and listened to it using my headphones that were plugged into the 3.5 mm jack, I used a 65 W wall charger to charge my laptop using the USB-C port, and I searched Amazon using my Ethernet connection. All of them worked well for my purposes.

Note: I was able to mirror my laptop’s screen on our TV as well as extend my laptop’s screen on our TV (mirror screen = same screen, extended screen = additional monitor). To extend your screen, your laptop’s graphics card must support this as well as the hub.

I tried using a USB wireless mouse in one of the USB-A ports and found that it sometimes (not always) stuttered while the other ports were being used.

I also successfully used the Alxum USB-C hub on our 2018 12.9″ iPad Pro. I was able to connect the iPad to my LG TV using the HDMI port, I opened various files on the microSD card and a USB flash drive, I used a USB wireless mouse (the faint grey dot on the iPad screen and TV screen is the mouse cursor), I performed web searches using the Ethernet connection, I used a 90 W charger to charge the iPad using the hub’s USB-C port, and I was able to listen to music through the 3.5 mm audio jack.

Unfortunately, the Alxum USB-C hub did not work with my Pixel 2 XL phone like my Anker PowerExpand+ 7-in-1 USB-C Ethernet Hub and my Aukey Link PD Pro USB-C Hub (or Unity C71 on the Aukey website). However, the Alxum hub does have a USB-C 100 W PD/data port whereas the others do not.

I discovered that while testing the hub using my laptop I lost connection with the USB-A flash drives when I disconnected the wall charger from the hub’s USB-C port. This was easily remedied by disconnecting the hub from my laptop and reconnecting it, but you might want to remember that and not disconnect the charger while you are doing any data transfers from those drives.

You’ll also notice that my USB-A flash drives are upside down. Some people may find the upside-down orientation of the USB-A drives annoying, but it really doesn’t matter much to me.

The data transfer rates really depend on both the hub and the capabilities of your storage media. The first screenshot above shows the transfer speed when I copied a large file from my laptop to the microSD card inserted into an SD card adapter on the hub (this was a U1 Class 10 microSD card that had a minimum write speed of 10 MB/sec).

The second and third screenshots above show the transfer speeds from my laptop to my USB 3.0 Type-A flash drives on the hub.

The first screenshot above shows the data transfer speed when copying a file from my microSD card in the hub to the USB 3.0 flash drive in the hub and the second screenshot above shows the transfer speed when copying a file from one USB 3.0 flash drive in the hub to another.

The screenshots above show the data transfer speeds when copying a file from the microSD card in the hub to the laptop (first screenshot), the USB 3.0 flash drive in the hub to the laptop (second screenshot), and the other USB 3.0 flash drive in the hub (SanDisk Extreme CZ80 16GB USB 3.0 Flash Drive – SDCZ80-016G-GAM46) to the laptop (last screenshot) – I love that flash drive, it’s so fast!

What I like

  • It has all the ports I need:
    • Ethernet port (1Gbps)
    • USB-C data/100 W Power Delivery 3.0 port
    • SD card slot (microSD cards need an SD card adapter)
    • two USB 3.0 ( or USB 3.1 Gen 1 or USB 3.2 Gen 1) Type-A ports
    • HDMI port
    • 3.5 mm audio jack
    • VGA port
  • All the ports worked well for me (I was unable to test the VGA port for lack of a VGA cable)
  • The USB-C port can be used for passthrough charging (up to 100 W; the hub uses 5 W) or data transfer (up to 5 Gbps)
  • It worked well on our 12.9″ iPad Pro (2018) and my Lenovo Yoga 730 13″ laptop

What I’d change

  • I would have liked to be able to use the hub on my Pixel 2 XL phone
  • A carrying case would be nice

Final thoughts

I enjoyed using the Alxum 8-in-1 USB-C hub. It has all the ports I need: a VGA port, an Ethernet port, a USB-C data/100 W Power Delivery 3.0 port, an SD card slot (microSD cards need an SD card adapter), two USB 3.0 (or USB 3.1 Gen 1 or USB 3.2 Gen 1) Type-A ports, an HDMI port, and a 3.5 mm audio jack. All of the ports worked well for me on my Lenovo Yoga 730 laptop and our 2018 12.9″ iPad Pro (note: I was unable to test the VGA port because I don’t have a cable to test it).

There are a few things to note about the Alxum 8-in-1 USB-C hub. If I had storage media inserted into the hub’s ports and I disconnected the charging cable from the USB-C port, this resulted in losing connection to the USB-A flash drives. This was easily addressed by disconnecting and reconnecting the USB-C hub to my laptop. I also noticed that when using a USB wireless mouse while using the other ports on the hub resulted in some interference (the mouse stuttered) but only periodically. And last, the hub didn’t work with my Pixel 2 XL phone like the Anker PowerExpand+ 7-in-1 USB-C Ethernet Hub or the Aukey Link PD Pro USB-C Hub did.

All-in-all, it’s a nice hub. The USB-C port can be used as a data port or a pass-through charging port (up to 100 W minus the 5 W that the hub needs to power itself), but the other USB-C hubs that I have were cheaper than this one, thus, I might suggest waiting until the price drops before purchasing it.

  2. About the wireless mouse problem, a warning I saw on a USB hub product page caught my attention: aluminium hubs may have problems with wireless USB receivers.

    This made me remember that I had problems with a receiver, connected on the front panel of a aluminium PC case I have, even with line of sight between the mouse and the receiver.

  3. Good review! I’m curious if this would work with a Chromebook. Would be nice to be able to plug into some speakers with the 3.5mm jack while charging on something like a Lenovo Duet that only has 1 USB-C port.

  4. Sure would be nice if there was a hub that had multiple USB C ports (like 4 or so) instead of all the other dated ports that I no longer require! OWC has a nice hub, but $150USD!

    1. Funkright – It is a little curious why these hubs don’t have more USB-C ports, especially since many new devices are adopting USB-C. $150 for a hub is a little pricey and thus, like you, I will be waiting for hubs that have multiple USB-C ports to come down to a more reasonable price!
