Belkin Thunderbolt 3 Dock Pro w/ Thunderbolt 3 Cable - USB-C Hub - USB-C Docking Station for MacOS & Windows, Dual 4K @60Hz, 40Gbps Transfer Speed, 85W Upstream Charging, w/ Ethernet, SD & Audio Ports

EDIT: It's now 5/2/25, zero issues with the dock or charging, working like a champ.I have an MBP M3 Pro, I went through multiple docks and dozens of reviews trying to find a dock that would give me:1. One cable to plug into the MacBook Pro.2. Must support dual external displays (I use 1080 not 4K).3. Must work in both open and clamshell mode.4. Must charge the MacBook Pro.5. Must support peripherals through my Cable Matters USB switch.6. No software installation is required, the dock must support all functionality out of the box without any additional software (ex: DisplayLink) or drivers.None of the other docks I tried worked, they would either mirror the display or not show the desktop on one of the displays at all, and the reviews were also useless since they were all old reviews for Intel not Apple Silicon.I chose this one because my company gave me a Belkin dock for my work MacBook Pro (also an M3 Pro). At the office I use that dock to get dual monitors in both open and clamshell mode. The Belkin dock they gave me was an F4U095, which is their Thunderbolt 3 Express dock, this one is the F4U097 which is their Thunderbolt 3 Pro dock. Because the Express version of the dock works, I thought surely this Pro version would work with my personal MBP M3 Pro.I am pleased to report that this dock does indeed fulfill all of the requirements above. Here are some specifics about my setup:* My mouse, keyboard, headphones and a USB flash drive are connected to a USB switch from Cable Matters (ASIN: B0CT6CK72N), I connect this to the USB-A port on the back of the Belkin dock through a USB-C cable (ASIN: B01GGKYIHS) and a UGREEN USB-C to USB-A converter (ASIN: B0CY1Y3TSQ). I connect to the dock through USB-A because with my setup there are no free USB-C ports on the back of the dock, there's one on the front but having the cable go around to the front is ugly.* Sceptre M32 monitor, connected by HDMI to DisplayPort on Belkin dock (cable ASIN: B015OW3M1W). This monitor is a gaming monitor with up to 144Hz refresh rate, MacOS lets me pick up to 100Hz using this cable and dock.* Acer monitor, connected by HDMI to Thunderbolt 3 Port on Belkin dock (cable ASIN: B083KTYFCW).My MBP M3 Pro is always in clamshell mode in a vertical stand, I never unplug it or remove it from its stand. Only one cable from the power delivery port on the back of the Belkin dock connects to my MBP, it provides 85W of charging power along with the connection to everything which is way more than enough, I used to charge at 67W even 45W would probably work, 20W would but only if the Mac was sleeping.❌ Problems Encountered:❌ When the MBP is sleeping and I wake it, only one of the monitors (the Acer) immediately works. The Sceptre is recognized in the Display settings in MacOS but the display is black and it will eventually switch to a different source as if it's unrecognized. I've heard other docks have this problem (CalDigit) but I'm not sure. At first I "fixed" this by unplugging the Sceptre from the Belkin dock and plugging it back in, but I found a better fix: switch the source on the Sceptre to the MBP, turn the Sceptre off immediately (as in don't wait for the source switch to finish), then turn it back on and it magically turns on with the proper source. This technique is easy to do and doesn't wear out the connector like disconnecting it and reconnecting it will. I don't blame this weirdness on the dock, the Acer works fine and I noticed on the prior hubs and docks I tried the Sceptre has always been the one that behaves weirdly, it's a Sceptre issue in my book, or maybe it's the HDMI to DisplayPort cable, might try switching this cable to the Acer monitor to see if it moves the problem to that monitor. I also believe this only affects setups where you have a monitor that's connected to multiple sources, where the Belkin dock is one of them (my Windows PC and Asus gaming laptop are the two other sources). If I unplug those devices completely or if they're both asleep, this problem goes away, so if you're using a setup where you only have the Belkin dock connected to the monitor, this is pretty much a non-issue.🤔 Miscellaneous Things:🤔 This dock behaves differently when you put the MacBook to sleep by explicitly telling it to (click Apple icon -> "Sleep") versus inactivity. If you explicitly put the MacBook to sleep through the Apple icon the dock will show an orange status LED (indicating no connection) and the dock will become cool to the touch, if you let it fall inactive the dock will show a green status LED (indicating connection) and the dock will remain warm as if it's in use. Neither state will affect charging or waking; even with an orange status LED it's still treated as if connected to the charger and you can still wake it up by hitting any key on the keyboard or pressing any mouse button. Obviously if you want to save electricity you'd want to explicitly put it to sleep. I noticed even if you explicitly put it to sleep the orange status LED will turn green for a minute here and there, some kind of waking going on but returns to orange for most of the time.🤔 It took FOREVER for the MacOS 80% charge limit (optimized charging) to work with this dock. I didn't unplug my MacBook Pro for roughly three weeks straight before MacOS finally recognized my "usage pattern", then it did the 80% charge limit and showed "Desktop Mode" in the power settings. I had given up at the two-week mark thinking it was broken forever with this dock. I don't blame this on the dock, the MacOS machine learning optimized charging feature has always sucked everyone complains about it. Now that it's kicked in it works better than it ever had though. At first if I had to restart MacOS due to an update (like with 15.3.2 and 15.4) on restart it would go up to 100%, then within an hour or two the charge limit kicked in, it showed "Desktop Mode" and stopped charging, the background power consumption then brought it back down to 80% and it stayed there indefinitely. Now if I restart MacOS for any reason update or otherwise (I usually restart it every week just to start fresh) it's already in "Desktop Mode" by the time I get back into MacOS and stays where it is without charging up to 100% at all. With this dock I've never experienced anything weird like it randomly going up to 100% for no reason, it's completely predictable and reliable now so I'm very pleased, stays at 80% indefinitely. I don't know how it would behave if I started disconnecting it from the dock though since I never do that...🤔 The "System Information" shows its state as "Not Charging" once it's at the 80% charge limit and nothing funny happens with the charge cycle count either, in case you're like me and worried some charging issue with the dock will cause extra cycles and wear on the battery. The charge cycle count in "System Information" has not increased since I started using this dock, it was at "9" when I started using the dock on 2/1/25, it's still at "9" today on 5/2/25 almost three months later.🤔 The "System Information" app shows that the charging wattage is 85W which correctly matches Belkin's claim. It also shows this dock in the Thunderbolt section which is why it works well with dual displays, other docks show up in the USB-C section because they're USB-C docks, not Thunderbolt.🤔 If you get your configuration set up and everything connected properly but something isn't working, try what I mentioned above about switching the source and turning the monitor off, or unplugging the monitors on both the monitor side and dock side, your monitor might be like the Sceptre monitor who knows.🤔 The Belkin Thunderbolt 4 docks would likely have met all of my requirements as well, but they cost more and have fewer ports.

I tried several cheaper brands and none of them worked. One got so hot you could not touch it. I finally paid a little more and saved a lot of frustration with this unit. More than enough ports and power for use on my iMac M1.

Works great in camshell mode, currently using it with my MacBook Air! both monitors work using a single usb-c port!

Updated 1/10/22: (lowered to 1 star)If you're using this with a Mac and a Gigabit wired ethernet connection, you're not going to get Gigabit speeds. I'm seeing more like 250Mbps. Interestingly, when I compare this dock with Belkin's USB-C to Gigabit adapter, their USB-C adapter works great. See the throughput tests in the pictures. I'm going back and forth with tech support, but I'm not optimistic.Update 12/3/21: (lowered to 3 stars)I'm now using this with an M1Max 14" MBP. In short, it's still working. Both 4K monitors work great and power delivery is fine. I don't think it does fast charging through the USB-C port like you get from the MagSafe 3 connector, but that's an Apple limitation. Also note that this is Thunderbolt 3 and the new M1 MacBook Pros are Thunderbolt 4. So we're not getting fully Thunderbolt 4 speeds. Practically speaking, I don't think this matters much.--> After over a year of use, one weird issue that I've noticed on both my old mac and my new mac is that sometimes peripheral USB devices connected to the doc don't reconnect after I plug the thunderbolt cable back into the laptop. It happens when I disconnect and reconnect the laptop. I have a USB audio interface that just uses MacOS's core audio drivers, e.g. no 3rd party driver, so if anything it's a mac driver issue. Or it's an issue with the dock itself. To fix the problem, I have to unplug the USB audio interface from the dock and plug it back in. I've lowered the review to 3 stars, because this limitation makes the dock frustrating to use. But I don't know if this is a Mac issue or a Dock issue.Original:I plugged it in, and it worked immediately and flawlessly, which I'm honestly surprised by given the reviews here.My setup: I have two 27" 4k LG monitors with USB-C interfaces (as well as HDMI and DisplayPort interfaces). I've been running them straight to my 2018 MBP 13" using USB-C. The LG monitors are gorgeous, but the MacBook forgets which monitor is which regularly, meaning that it swaps which monitor is on the left and which one is on the right. This is super annoying, and I hate it. Despite the terrible reviews for this hub, I figured it'd try this. My MBP has 4 Thunderbolt 3 plugs, and this hub indicates that it supports 4k at 60 Hz for two displays when using Thunderbolt 3. Well, as I said, I plugged everything in and it just worked. One monitor uses the USB-C Thunderbolt on the back of the hub. The other monitor uses the DisplayPort plug. I have 3 USB-A peripherals plugged into the back of the hub, all of which require full power to run. My webcam runs through the USB-C monitor's USB-A hub on the back of the monitor, and that works fine, too! The Gig-E ethernet plug passes my network speed test. I've tried the front USB 3.1 plugs and the SD Card reader, and they work. I haven't tried the mic jack yet. So far, it just works, and even better, the Mac doesn't forget which monitor is which. The only complaint I have so far is that the hub gets really hot, so I worry about long-term reliability. 4 stars for now until I see how it lasts.For those of you having problems, I'm not surprised. My experience with multi-monitor hubs is that they are very temperamental to system and monitor combinations. I don't really know why, but I've abandoned several over the years. You basically just have to try them out and return them if they don't work.I'll update the review after I run this for a few months, and after I run this with Big Sur.
