Amazon Basics Thunderbolt 4 Docking Station, Dual 4K@60Hz Display Support, 85W Power Delivery, 3X Downstream TBT4, 1xUSB A 3.1, Mac/Windows Compatible, Black, 4.76 x 2.84 x 0.86 inches

Edit May 2, 2026: This Amazon Thunderbolt 4 hub is still an amazing deal for me. It has brought my iMac 2017 a new lease on life and I can wait another 2-3 years before I recycle my old friend. My home network has benefit the most in that all my WiFi gadgets run as fast and as stable as their WiFi cards will allow. Edit April 11, 2025: I have to change my review from three-stars to five-stars due to not properly connecting the Amazon Thunderbolt 4 Docking Station to my 2017 iMac, which is limited to Thunderbolt 3. The issue is that you must use the included OEM Thunderbolt 4 cable that comes with the Docking Station from Amazon to get the proper upstream/downstream flow from the iMac [Host] to your connected devices. This is necessary. I'm not sure any other Thunderbolt 4 cable will work as this one is proprietary. 🧐 Anyway, I made the correct connection of the Amazon OEM Thunderbolt 4 cable to one of the Thunderbolt 3 ports on the back of my iMac and everything began to work as they were supposed to. I get 40Gbps upstream/downstream from my iMac now, when before it was "No Device Connected." This means that speed through the Amazon Thunderbolt 4 Docking Station, since properly attaching the OEM cable, will only be limited by the client device's speed capability up to 40Gbps. 😊 My iMac 18,2 (21.5-inch Retina 4K, 2017) is equipped with: • Two Thunderbolt 3 (USB-C) ports • These support speeds up to 40 Gbps (gigabits per second) when connected to Thunderbolt 3-compatible devices. Additionally, those same ports support: • USB 3.1 Gen 2 (up to 10 Gbps) • DisplayPort 1.2 • Power delivery and charging [15W (5V at 3A)] • Backward compatibility with USB-C devices Original Review: I connected this Amazon Basics Thunderbolt 4 Dock to my 2017 iMac 18,2. It only would charge the iPhone 16 Pro Max after I connected this Thunderbolt 4 Dock to a UGREEN USB C/3.2 Hub connected directly to one of the Thunderbolt 3 Ports on the back of the Mac. I wanted to see if I could get super fast speeds between my iPhone 16 Pro Max and The Apple Music App due to my having over 39K songs I downloaded or ripped from CDs. I quit paying for Apple Music Streaming because I always only listened to music that I already owned. Well, the Amazon Basics Thunderbolt 4 Dock would not allow super fast speeds transferring files between the Mac 18,2 and the iPhone. It only allowed charging at a pretty fast rate. Ultimately, I took the Amazon Thunderbolt 4 hub out and just use the UGREEN USB 3.2 hub as it fast charges my iPhone, transfers music files very fast, and connects all USB 2.0/3.0 drives. The Amazon Basics Thunderbolt 4 hub is set aside for when I get a new Mac that has Thunderbolt 4/5 instead of Thunderbolt 3. Otherwise, I assume this Amazon Basics Thunderbolt 4 Docking Station works well.

When I look for things to plug into an outlet and then into my equipment, I'm checking for a few things, but mainly power supplies because a lot of manufacturers skimp on these, and that's just not right. So I'll start with the power supply that comes with this unit, which is a big, beefy and heavy power supply made by Chicony, Model A18-135P1B, which is grounded, well-made and is UL and CE Listed. These things do matter to me. While it's long and wide, it's actually quite narrow and mounts under a desk very nicely. The dock itself is also very well-made and reminds me of any number of other higher-end units on the market in both size, shape, design and features. it has all of the ports I need (three USB-C/ThunderBolt 4 ports, one on the front to connect to your computer and two on the rear), three USB-A ports, again one on the front, one on the back, an Ethernet port, one HDMI port and a headphone jack. If you need more than this, hubs will always work, but so far I've been satisfied. Connected to my MacBook Pro M4 Pro, I get every ounce of speed and performance I expected with an external thunderbolt 4 drive, the audio works great passed-through, although I use a 3rd-party amp plugged into it's USB port and have noticed no issues at all. It's featureful enough to satisfy my needs, compact enough to fit under my laptop stand, and inexpensive enough to have me still scratching my head. I can't recommend it enough. If you're worried about spending too much on the flagship products, getting a dock that fits on your desk, but also worry about plugging something cheap into your valuable equipment, this is the dock for you. Great fit and finish all around, wonderful quality and attention to safety details like the outstanding power supply convinced me.

Major Charging Issues After a Few Months I bought this Amazon Basics Thunderbolt 4 Pro Dock to use with my Dell XPS (which has native Thunderbolt 4 ports) to drive two 4K @ 60Hz monitors. Unfortunately, it has been plagued with technical issues. The Issues: Boot-Up Screen Flickering: From day one, whenever I power on the laptop, the BIOS and Windows logo flicker and blink heavily before finally reaching the Windows logon screen. Charging Failure (Trickle Charge Only): It worked decently for about three months, but then my laptop stopped fully charging. I initially assumed it was a BIOS battery protection setting, but it has gotten progressively worse. The dock now only "trickle charges" my laptop—taking a staggering 8 hours just to go from 30% to 44% before stalling completely. It's the Dock's problem: To rule out a laptop issue, I tested my original Dell travel charger. The OEM Dell charger handles a 100% charge in 3 to 4 hours with zero issues. This dock simply cannot sustain the power delivery it promises over time. For a premium Thunderbolt 4 device, failing after just three months is unacceptable. Avoid this unit if you need reliable power delivery. The power on blinking is an indication this dock is not syncing with Laptop (driver issues).

This product does not work with ANYTHING AMD as far as I can tell (can’t get TB3/4 AIC 5pin header card for AMD board), research etc. I thought it would work with my minipc (USB4), or a new motherboard I'm researching right now for a new build. NOPE. I thought I could get a thunderbolt addon for my board. PCIE to get it to work. Nope. Only ebay uk/jp etc and they don’t ship USA. It is basically INTEL only (laptops or SPECIFIC motherboards). Also the description leads you to believe you can hook it to USB4 or Thunderbolt: "Amazon Basics Thunderbolt4/USB4 Pro Docking Station", that lead me to believe it would double as a USB4 dock. Nope. Not knocking the product, reviews say spectacularly with INTEL. But for an AMD buyer it's a return. Just be aware. Gave it 4 stars because build Quality seems very good, ports were exactly what I needed, but didn't know about no AMD (at least NOW). IMHO the description should be changed to "Amazon Basics Thunderbolt4 (NO USB4 dock) Pro Docking Station", but that is just me. I'm an ex-IT admin/support (and had a pc biz for 8yrs where I was the only tech), so if it fools me, how many others are disappointed. Thunderbolt to me on the whole isn't as good as Intel would like it to be. Look at the PCIE TB4/TB5 card reviews and tell me people seem happy with them. USB4 seems much better compatibility wise (works on both Intel/AMD pretty much anything). My UM790 Pro from minisforum has 2 usb4.0's which I thought would work with this dock, or my TB4 capable board I'm looking at (a little research left to support all my crap I hook up...LOL). But both are dead ends here. Amazon, please update the description. Even the Asus/Gbyte PCIE cards seem to not work on AMD (14pin not 5). If someone has this dock working on an AMD based system (today, just did it?), feel free to state so and I'll eat my hat so to speak :) Again not knocking the PRODUCT here, it's just a compatibility issue. I'm not even sure if the dock works (before returning now) other than the green light came on when plugged in ;) P.S. Stick with USB4 for now :) Why would you buy Intel with AMD kicking them in gaming, LLM, media creation etc for home use? AMD’s been rocking Intel's world for some time now in many things but can't quite seem to capitalize yet. Again, Design of this is great, quality seems good, easy to hook up etc, size was great too, fits easily on my desk. Got a Dell 30 and 27 I would have loved to see run from it, but oh well. Good luck, and God Bless to everyone. (edited to add Intel side 14pin header, AMD 5pin on most if not all mboards).

Headline: Great TB4 performance, but serious USB daisy-chaining issues The dock is affordable and meets all the standard requirements for a Thunderbolt 4 dock, including successful dual-screen support on my M4 MacBook Air. However, I’m rating it 3 stars due to its internal architecture. The dock USB-A ports are buried five levels deep into a USB chain because the dock uses four internal hubs. This caused major compatibility issues; for example, my DAS mechanical keyboard (which acts as its own hub) ended up at Tier 8, making it completely inoperable. If you use devices with built-in hubs, you'll likely have to plug them directly into the dock or your laptop instead.

This is a great docking station! It has a durable metal casing, with just the right amount of ports, and a good compact size. I decided to try it out given that the competitors and "name brands" are charging around 2-3x the cost for a simple thunderbolt docks. I have been shopping a long time, and everything I was looking at was either incompatible, expensive, provided the wrong ports for my needs, or was too bulky. When I just wanted simple function. I have a MacBook Pro with a M3 Pro chip, and I'm generally happy with it, but it does not support MST and daisy-chaining. So, I have been looking for a good thunderbolt docking station that would allow me to upstream charge my laptop, and at least two downstream ports to cast my dual-monitor setup. I also thought it would be a bonus if I could attach my mechanical keyboard to a USB-A port, if available. When I came across this, it seemed like a perfect docking station to hook my entire desktop setup to, so I could easily connect my laptop and have it come to life. I have done heavy work if it is writing and debugging code, editing large files for photography projects, running VMs, etc. I have not yet run into any connectivity, speed, or quality issues while using this dock. I was very happy that it is so compatible with MacOS. Reading the many reviews on the competitors, they either didn't support every OS or it was grainy and slower with MacOS. I switch between my MacBook, or my dual-boot Lenovo with Windows and Linux. I will be testing with the Lenovo soon, to see the compatibility with all OS. I am so far very happy with the compatibility and simple yet high quality product. TLDR: If you want a simple docking station with a good performance at a reasonable cost, I would highly recommend getting this one!

If you get this for a low price, it's OK. This dock seems like a killer combo when it's on sale. However, there are many problems like other reviews have pointed out. There are a few USB detection problems and drop outs if you're using hubs or daisy chaining things. Also there's no VRR and HDMI is limited to 60Hz. Didn't have these issues on my old Kensington TB3 dock. Not sure if it's worth the hassles troubleshooting the USB problems constantly and I've switched to a Bluetooth keyboard and mouse in the meantime. I'll try a few combinations before I give it. Sad, it's great when everything is working, but most of the time it's not.

Been using it daily for about a year now and it's had virtually zero issues. I have lost communication with my keyboard twice over usb on this. I'm not going to knock a star for that though because it could just be me pushing my machine too hard. That said, when it did happen I did have to unplug the dock and and plug it back in. I use it for a 1440p monitor, mechanical keyboard, Yeti mic, and a 990 pro in a 3.2 enclosure. It would be nice if it had a few more type A ports, but again, not going to knock a star for something I knew about going in. It does get hot at times though, so I am a little concerned about it last more than 5 years.

Amazing - finally a solid TB4 dock that works well and isn't overpriced. Very happy with this. I also have the Dell but it is way more expensive. I don't love where the USB-C TB port is... why right on the front and not on the side or back? But minor in the grand scheme of things.

★★★★★ Excellent Thunderbolt 4 Dock – Works Perfectly with My Mac Studio I purchased the Amazon Basics Thunderbolt 4/USB4 Docking Station to expand the connectivity of my Mac Studio, and it has exceeded my expectations. The dock was truly plug-and-play. It was recognized immediately, and all ports worked exactly as advertised. The three downstream Thunderbolt 4 ports provide excellent flexibility for connecting high-speed storage, displays, and other peripherals. I particularly appreciate having multiple Thunderbolt ports available, as many competing docks offer fewer options. Performance has been excellent. External SSDs operate at full speed, displays are stable, and I have experienced no disconnects or reliability issues. The dock feels solid and well-built despite carrying the Amazon Basics name, and it compares favorably to more expensive alternatives. For anyone looking for a reliable Thunderbolt 4 dock without paying premium-brand prices, this is an outstanding value. It has become an essential part of my desktop setup and I would not hesitate to purchase it again. Pros: • Easy plug-and-play setup • Three downstream Thunderbolt 4 ports • Reliable and stable performance • Excellent value for the money • Solid build quality Cons: • Only one USB-A port, which may be limiting for some users Overall Rating: 5/5 Stars

Needed a thunderbolt to support my displays. This worked great

This dock is pretty affordable as far as Thunderbolt 4 docks go, so I didn't necessarily expect the best build quality. Turns out it's surprisingly sturdy, looks great in person and works just as advertised. Recommended.

Poor performance, avoid: - doesn't always supply of power to my laptop. All of the devices connect fine, but no power is supplied to charge the laptop, annoying - internal ethernet is slow. external usb-c ethernet adapter (which uses the same chip as this dock) is faster - 10GbE USB network adapter only runs at half speed with it. NIC works fine directly connected to laptop. Should have plenty of bandwidth for that - power button is hard to find by feel and not well labelled. almost perfectly flush, forcing you to look for it rather than reaching it by touch
