Excellent Quality and Reliable Performance from Anker’s 8-in-1 USB-C Hub
I’m really impressed with this Anker USB-C Hub with Ethernet (8-in-1). The build quality feels premium, setup was completely plug-and-play, and all ports work flawlessly with my laptop. The Ethernet connection is stable and fast, which has been perfect for work calls and large file transfers.
I also love how compact and portable it is while still offering plenty of connectivity options. HDMI output looks great, USB ports transfer quickly, and the SD card reader is very convenient for photo and video work.
Anker continues to deliver reliable products, and this hub is no exception. Highly recommended if you need a dependable all-in-one USB-C hub for productivity or travel.

Works great (quick test)
Just got this and tested and works great
I attached to my MacBook with Ethernet and had a solid connection
I tested my steam deck by plugging in Ethernet then adding HDMI then adding power and everything worked as it was plugged in
I tested my Nintendo switch even though it clearly states it's not supported and it did not work at all. Even the power pass through did nothing. This is not even remotely a problem since it was advertised as such but I figured it was with a try and worth noting

Despite some caveats; this is a versatile hub
The Anker 555 8-in-1 USB-C Hub is a good buy if you’re looking for a hub from a reputable brand. I use it with an M1 Macbook Air, and it has been reliable so far. This hub has the following ports: 1 USB-C data port, 1 USB-C Power Delivery Port, 2 USB-A data ports, 1 HDMI port, an Ethernet port, and a microSD/SD card reader.
Charging, PD (Power Delivery):
To keep my Macbook charging, I connect a PD (Power Delivery) capable cable to the USB-C port meant for PD. (The other USB-C Port on this hub is meant only for data.) Once connected, the hub will eventually become warm to the touch, but this hasn’t caused any problems so far.
Video Performance - no problems in 1440p
I can connect my 1440p 144hz monitor to this hub’s HDMI port and my Macbook Air has no problem outputting a refresh speed of 144hz, as well the lower refresh rates of 120hz and 60hz. (I do not have a 4k monitor, so I could not test that.)
USB-A Ports - works flawlessly
I’ve tried keyboards, USB Drives, and even gaming Mice. All of these devices work as expected when connected to the USB-A Ports.
Ethernet - Excellent speed
I've connect this hub using an Ethernet cable to Gigabit speed Internet. The speed is just as fast as other computers on the network, and there is no slowdown at all, even with most of the ports on the hub being used.
Gaming Keyboards with USB-C connectors - some issues.
Some peripherals such as keyboards with USB-C connectors may not work on the USB-C ports on this hub. I tried using a Glorious GMMK Mechanical Keyboard and it did not work with this hub’s USB-C ports. (Of course you could try to simply use a USB-C to USB-A adaptor and then connect via the other USB ports on the hub instead.)
Extension Cable - Use a Thunderbolt 4 cable
Although this is totally optional, I like to use a small, 6-inch USB-C Extension cable to allow this hub to have more slack away from my laptop when connected. To allow this to work, I had to use a Thunderbolt 4 extension cable. I've tried other cables such as a Thunderbolt 3 extension cable. However, some of the attached devices on the hub were not recognized. Only the the Thunderbolt 4 extension cable allowed all my attached devices to be recognized.
Other devices
I have successfully connected an external SSD via the USB-C data port on this hub. I also regularly use an external DAC using the USB-A ports connecting to an IFI HIP DAC. Both of these devices work perfectly with this hub. Data transfer speed is rated at 10Gbs, though I haven't actually confirmed that. It works well enough for my purposes of transferring text documents and the occasional batch of vacation photos to my external SSD.
Conclusion
This hub from Anker is rated at 10Gbs which is plenty for me. But if you regularly transfer large amounts of data (like for video editing), I would instead recommend a powered docking station such as those from CalDigit. But for me, this portable hub does everything I need, and for much less money.

Almost perfect, could use one more USB-C Gen 2 port and a metal case instead of plastic.
Never really had any problems with Anker gear, I've come to trust the brand name. This little hub is almost perfect for use with my 2019 MacBook Pro, but where Anker really dropped the ball is by not adding one more USB-C port. I mean, there's two, but if one is dedicated to power devices only that doesn't really leave much room for expansion by only giving you one extra, I mean they were thoughtful enough to give you two USB-A ports. I do like that the USB-C and two USB-A ports are version 3.2 Gen 2 rated for up to 10Gbps transfer speeds versus Gen 1 at 5Gbps. The plastic casing does get hot, not sure if aluminum metal would be any better, but it would feel nicer, plastic just feels cheap. Also, a dark case with dark letter printing doesn't work because you can't see the writing, should have used lighter letter coloring. Otherwise, solid performer. I'll keep it along with my other one because having two hubs with a laptop is convenient so I don't have to always haul a hub around from place to place.
PROS:
• 1 USB-C port version 3.2 Gen 2 rated up to 10Gbps.
• 2 USB-A ports version 3.2 Gen 2 rated up to 10Gbps.
• Also includes, HDMI, Ethernet, SD and micro SD card ports.
CONS:
• Plastic casing, gets hot.
• Should have one more USB-C port.
• Port description lettering is too dark, gets lost against dark case color, should have used white or silver lettering instead.
• No audio port.

Does everything, super portable, robust construction
This is a super useful hub. I also used the Anker 341 7-in-1 hub for years, and it was very reliable for every feature, and the 555 8-in-1 looks to be of the same quality. The ethernet adapter is a great addition, and it works right away at 1G speeds on Linux 6.18 and even Android 16. I upgraded from the 341 to use this to connect to and configure devices from my desktop without having to drop my normal ethernet connection, and it is fantastic for that. It's a real swiss army hub, perfect travel size, and incredibly handy.
