Thunderbolt 4 Dock – 21-Ports Laptop Docking Station Dual Monitor for MacBook Air/Pro (M1–M4), Windows & Chrome – Dual 4K or Single 8K Display, 40Gbps Speed, 90W Charging, USB-C/A Hub

Plenty of power, ports, and excellent customer service to boot
What other users have said about the audio quality suffering is the truth. The dock itself is an absolute powerhouse, especially coming from a 90 watt dock that began to have a flickering issue with external monitors. I have all but a USB-C port occupied in this dock and it hasn’t skipped a beat, is snappy and responsive. If you’re an audiophile and need premium sound at all times, maybe look into cable shielding options since this dock seems to produce a constant background ‘hiss’ at all times. Its okay for online meetings and the like, but does get annoying enough that I keep the volume muted when not using it. ***UPDATE on the audio issue: I installed one of these onto the audio cable to my external speakers – the fix was immediate and the hiss is no longer there: https://a.co/d/0YKXben=============================================================================UPDATE: So exactly two months later – to the day – the dock died. It got power but wouldn’t throughput to the laptop nor any connected device. I’d get the “blump-blump” notification on Windows that something was connected, then it would disconnect and just kept doing that over and over. Long story short, the return window had closed, but that’s where Amazon customer service put me in touch with the manufacturer. They’re based in Florida and agreed this sounded like a defective unit, so they *immediately* dispatched a replacement. Two days later I was up and running again with a free replacement and instructions to send the defective unit back. Its great when a company stans by their product and works to make sure you’re getting everything you paid for. The photo is my WFH setup, and its running everything pictured with no issue. Highly recommend if you need something with more power, more ports, and the ability to build a “command center” at home with only one device.

Something shouldn’t start failing after less than 2 months
I purchased this product October 2nd 2025, It started making loud noises when I turned it on starting November 18th 2025. Today November 29th it has shut down and restarted while in use 3 times already, this is the first day this has happened. Pretty pissed right now.When it works, it is great, had seen some reviews say it wasn’t reliable but a lot of good reviews too so I was hoping that was a fluke. I run a Macbook Pro M3 Pro with 2 External Monitors and 2 External Drives connected.I work from home so this is pretty inconvenient to have an expensive peripheral start crashing on me after less than 2 months of use. Thought I did good research before buying this but I obviously may have been wrong.

Good performance
Bought this docking station because I ran out of ports (something that happens frequently nowadays).This docking station is well build. Metal case and heavy which means they didn’t go cheap.The power adapter and the cables are thick which is also a good thing. The gives me more confidence to say that they made a good product.All the ports work well so far. I haven’t use all of the ports at the same time and I haven’t connected any extra screen which might raise the heat level. It doesn’t get hot with small things connected (usb sticks, phone charger, mouse and keyboard receiver).If you test transfer speeds make sure the port in your computer supports the docking station speed, if not you will get different numbers. For the rest of simple mortals that only need reliable extra ports to connect stuff, this will do well.

My laptop has literally only 2 ports, and one of them is often used for charging. This amazing little gadget solves all my port issues. It charges through the same wire as it transfers data. Data transfer is super fast as is the charge speed. The dock is tiny but mighty, it has some heft to it. Definitely worth the investment

What’s included:- Smartlinx 11 port docking stationThe Smartlinx 11 port dockings station is stable and consistent with respect to power, with the ability to have a dual monitor setup.The docking station is made of a combination of aluminum and plastic and has good ventilation that prevents the docking station from overheating under normal load. Additionally it has an overall height of about 0.5″ which is appealing to me due to my setup and wanting to have a docking station slip in under my portrait configured monitors. In addition to being quite thin it also has an approximate width of 15cm x 7cm (roughly speaking).The docking station has a bright blue LED that stays on when powered and it’s worth noting that this is an always-on docking station since there is no power button to turn on and off the docking station.Setting up the docking station is very simple with a plug-and-play design that makes this quite useful for my setup which includes a Windows based environment.The main attraction of this docking station for me was the possibility of connecting it to my always-on miniPC as well as a dual monitor setup that consists of a portable monitor as well as a 27″ desktop monitor, so I was eager to experiment and test this docking station with respect to the characteristics that are important for my desktop setup.While this docking station has some strong points, especially around power delivery and stability, the display configurations are more limited that I was expecting given my always on mini PC setup.Power delivery:With the dock powered from the wall, it reliably delivers USB-C power to my host system (miniPC) and remains stable even under load. I power my mini PC through the USB-C cable and port to the appropriate port on the docking station while simultaneously running an external monitor in addition to USB peripherals including including drives and a keyboard and mouse receiver.Although the docking station advertises up to 100W PD, this is more of the theoretical value vs the real world output due to various power related items. Given my mini PC’s power draw this is not an issue but with more advanced laptops, this may or may not be sufficient for your circumstances.Display support:When it comes to the dual monitor display, let me point out a few things.First, I had originally tried to setup this docking station with my mini PC connected to a large 27″ monitor as well as a portable monitor, but because of the limitations associated with the mini PC’s hardware this setup was not successful and only power and data were passed through to the portable monitor requiring the addition of an HDMI cable to complete the connection with a mini PC with no GPU.HOWEVER, with a laptop with a GPU such as my Acer laptop, the docking station’s ability are optimized, because this docking station uses native GPU settings due to it’s thunderbolt 3 port rather than using software and compression. So when setting up the docking station with a laptop equipped with a GPU (in my case an Nvidia RTX 3050 GPU 6.0 GB) the ability to connect to two desktop monitors is possible – one through the DP and one through the TB port. Using this setup and my Dell P2720DC monitors which are equipped for connection through USB-C as well as through a DP cable, the two monitors were able to work without issue. One utilizing the DP cable and the second using a full service USB-C cable.Therefore, what we can say is 1) this docking station IS capable of connecting to dual displays as long as the hardware allows for it and 2) in cases where two displays are problematic, it is possible to make the connection through additional cables such as in the case of a mini PC and a portable monitor + desktop monitor setup.There is also additional benefit that comes from the fact that there is no compression taking place and the docking station is utilizing the native GPU for display.Stability:My experience with the docking station is that it remained stable over an extended period of time. As I noted earlier, it is connected to an always-on mini PC and although the dock gets a little warm I have not had it overheat or disconnect any devices due to performance issues. As I noted earlier, plug-and-play setup is great with Windows and no driver is required.Overall:If this docking station is good for anyone it will be a good fit for either a single external monitor connection via the DisplayPort or a dual monitor setup as long as the hardware allows for it. The 4 USB 2.0 ports and additional ports for things such as a mouse, keyboard, external drives and more are quite useful as well. The performance on higher resolutions is good, with my 27″ monitors with a 2560 x 1440 display able to achieve 60Hz which is expected.Those who may find some issues with this dock will be those like me, looking for a natural dual-monitor setup, or a setup with a mix of monitors ie portable monitor + normal desktop monitor when hardware is limited. Dual monitor setup may require some work in those cases, but for those using a typical laptop to desktop monitor #1 + desktop monitor #2, if not equipped with USB-C connection, it will still be possible to connect trough adapter cables such as USB-C to DP or USB-C to HDMI.In the end the dock works well.Cheers,

I’ve been using this Smartlinx Thunderbolt dual monitor dock for a bit now and I’m honestly impressed with how much it offers. I tested it with my mini-PC, a 43-inch 4K monitor with DisplayPort, and a portable monitor that takes USB C video. At first, I had trouble getting dual monitors to run at the same time, so I started troubleshooting by trying one monitor at a time. A single display worked perfectly, but I just couldn’t get two running together.That pushed me to look back at my mini-PC specs and I realized the issue was on my end. My USB C port supports data, PD and Alt PD, but it’s only USB 3.2. Since I wasn’t able to test this dock with a true Thunderbolt device, I can only confirm a few things. First, there is no backward compatibility here, so you really need to make sure your video source has at least a Thunderbolt 3 interface. Second, the number of USB ports on this dock is seriously impressive. I plugged in two mice and two keyboards along with one monitor and everything ran smoothly. I didn’t get any lag, no weird delays (mice and keyboards), and the monitor didn’t flicker or stutter at all. Best of all, I did not experience any overheating at all.I also like that it includes USB A 3.0 port. Being able to get 5 Gbps speeds on top of everything else makes this dock even more useful for data transfer. My only small complaint is that I wish the manufacturer had added at least one HDMI port. It’s not a dealbreaker for me though because a lot of newer monitors already support USB C video anyway.Overall, given the number of ports, the solid build and the clean design, I think this dock is absolutely worth five stars.
