Hiearcool Docking Station for MacBook Pro, 4K Triple Display 9 in 2 Laptop Docking Station Compatible for MacBook Pro/Air Thunderbolt 3 Multi-Port Dock USB C Dongle (HDMI PD3.0 SD TF Reader RJ45 USB)

I have been using this dock for about a month now with a 13" MacBook Pro for my IT administrator work. Before starting the review, it's important that your laptop have two USB-C (PC) or Thunderbolt 3 (Mac) ports because this dock requires it. There are so many ports on this dock that it simply can't work with just one. This is not a problem at all for most laptops but it is worth noting. The dock connects perfectly to the two Thunderbolt 3 ports on the right side of my Mac.Once plugged in, the dock can send up to 100 watts of power which is absolutely incredible. To get a little bit technical, every single Apple laptop has power requirements that can be met by this dock. Even the most powerful and expensive MacBook Pro, Apple's 16" 2019/2020 version uses 96 watts. Most MacBook Pros use 29, 30, or 61 watts. Having 100 watt capability is a sign of the quality of this dock.The other ports are as equally great. Having dual HDMI ports is something that might seem excessive until you try it. A lot of people use their laptop screen as one monitor and an external as another. This is fine but once you get used to having two large monitors to work with, it's very hard to go back. The laptop monitor can still be used when two externals are running too. This makes multitasking incredibly efficient. You can use different monitors to permanently have certain essential programs open, like email, chat software, financial data, etc. If your monitor supports it, this dock can do not just normal 1920x1080 resolution (1080p) but also 4K which is a crazy 3840x2160. This is amazing for gaming or monitors often used by programmers.The other ports are impressive as well. In addition to a USB-C/Thunderbolt 3 port for charging, there is another one for USB-C devices like an external hard drive. Depending on the quality of the drive, the speed when doing this can be virtually identical to your internal storage. There's no need to pay more money for an increased internal storage when you can use a USB-C external drive or buy an SSD, M.2 drive, or other flash storage and put it in a USB-C adapter. If you already have a USB 3.0 (or even 2.0) drive, you can use it in the two additional slots on this dock. To make it crazier, if you don't have that but have flash storage from a portable device or phone, you can insert it into the SD card slot, but you'll need a MicroSD to SD Card adapter which are very cheap and easy to find online.Finally, having hard wired internet isn't essential for lots of people because WiFi is very sufficient, but it's essential for certain people and environments. Nothing compares to gigabit ethernet speeds and since many modern laptops don't have a port, this dock is incredibly helpful. There is an ethernet port on the short/narrow side of the dock that some people might miss. If you can hard wire, do it! For things like stock trading, gaming, large downloads, and running cloud applications, you will absolutely notice the difference when using a wired internet connection.This dock is awesome. Plug one device in and you get so many things devices ready for you in an instant. When you are done, just unplug it and you're done. There are no worries about overheating because the device doesn't sit directly next to the laptop since the dongle wire gives it room. They thought of everything you could possibly need in a modern home or office environment. You will not be disappointed with this dock.

I really had my doubts about this but this little gem works perfectly! And, to be honest, it works better than it should. Other than the new MacBook, everything else I’m using is embarrassingly old. I’m using dual monitors that don’t even have HDMI — I’m using pretty cheap old adapters to go from DVI to HDMI on one and VGA to HDMI on the other. I also plug in an external webcam so I can close my MacBook lid (the camera, actually, is pretty new). I also plug in a Jabra external conference call speaker/mic. AND, because I wanted more USB ports, I plugged in an old cheap 3-port USB hub! Lastly, the SD card reader works with my SD cards just fine. Now, the unit does get warm but not as warm as the MacBook does. Like I said, I can’t believe this has all been totally plug and play — the Mac even recognizes the things I plug into the USB hub hanging off the docking station! It’s been only a week but...GEEZ, this thing has more than exceeded my expectations! I run dual monitors, Zoom calls make up the bulk of my 12-hour workdays, and this unit doesn’t miss a beat. I had one scare when I first plugged in my external camera — it would switch off every couple of minutes. Restarting the MacBook fixed that right away and I remembered that the camera did that with my first laptop as well. I also run Win10 via Parallels and nothing seems to phase this unit. I hope it’s got a long life ahead of it! Bottom line....BUY THIS THING!4/3/21 -- Well, the 2nd HDMI port has gone bad after just a 10 days or so. I've eliminated the possibility of the issue being the monitor or cable since I swapped both and still no joy while my monitor #1 will work in either port. I'm going to return and replace with another unit tomorrow and see if it is just a one-off issue.4/5/21 -- UPDATE -- So, I believe the monitor failure issue was (you probably guessed it!) MY FAULT! Remember, in my first installment of this review, I'd hung another cheap old USB hub off one of the USB ports to get more USB port availability? Well, that seems to have been the issue. I just overtaxed the unit beyond what it was designed to do. I was STILL able to configure a way to get what I wanted! I had to ditch the old USB A-based hub that was causing the issue and was able to replace it with a USB C-based hub that I found here on Amazon for about $10. Using the USB-C port to hang this new hub off of does NOT show any issues at all. NOW...I'm about to replace my old 24" monitors with brand new 27" 4K monitors to REALLY push this little dock to its limits! I will post my results within the next couple of days. Some of you might be wondering why I don't step up to their larger dock that offers a few more ports. I really considered that but it only uses one USB-C port on the MacBook Pro. I'm more confident in docks that use TWO USB-C ports on the MacBook Pro especially when using dual monitors. Now, I haven't tested the one-port models but that's my opinion. At this point, though, I would still say this is one awesome little dock!

This handy, small docking station turns your Mac Pro into a powerful 3 monitor workstation! Note: This product is for a recent Mac Pro ONLY. It is not meant for a Windows PC due to the dual male connector that gets plugged into the computer. The device does what it says it will do: capability to extend the Mac with 2 additional HDMI monitors at up to 4K each. I am using a 4K with a 1080p monitor - yes, mixing and matching does work. The USB Type C charge port allows you to connect your Mac charger to it and that powers the hub while also charging your Mac during use. The Gig-LAN RJ45 is quick and reliable. The 2 USB 3.0 Type A ports are very useful and allow me to connect a dongle for external keyboard/mouse and external hard drive. The SD card slots allow me to read photos from respective cards. A USB 3.0 Type C appears to be available for my future expansion. This small, low cost device allows me to do a lot and I really appreciate it. The product arrived from the vendor relatively quickly as promised.Now for the Cons: (1) The device gets HOT! Do not be surprised when you feel the outside of the case. At 120 F, it may surprise you, but not burn for fingers as long as you do not leave it there too long. So far, the device is reliable and has not failed, but operating at these temperatures may be concern as I imagine the chips inside may be much hotter. (2) It is not Windows compatible, but no complaints since I prefer a device that is made specifically for the Mac as that is what I am using it for. (3) Display port would have been nice, but since the both HDMI is 4K capable (albeit, only 30 FPS), that’s fine. The quality of the video is sufficiently sharp on 4K monitor. (4) Not name brand (nit picking here).Summary: It does what it says it does, arrived reasonably quickly, and performs equivalent or better than docking stations costing twice as much. It may run a little hot, but appears reliable so far. I would recommend this product from this vendor. Overall a Good Buy!

I bought this to add two displays to my 2020 MacBook Pro. I've bought several different types of docking adapters that claimed to support multiple displays, but did not work well. I can report that I've been using this for several months and it works great!The MacBook, of course, has very limited outputs, just one Thunderbolt port in addition to the Thunderbolt port used for the power cord, so you need an adapter. This display takes over both of the Thunderbolt ports and provides the same functionality through its ports.I work online all day. I use two 27" 1920x1080 (FHD) displays, and keep the MacBook open in the middle. So this is a 3-display setup. This allows me to manage the call, or to present, using the MacBook display while having one monitor for email, Slack and other messaging, and another monitor to search and read documents, my notes, schedule or other distractions! So I wanted "extended" displays, where all displays are unique, and can be organized side-by-side (the mouse moves across all displays). Most adapters only did "mirrored" displays, which means one or more of the big monitors is a copy of the laptop display. Not useful for me.For me, this adapter smoothly supports these two HDMI displays, a micro-USB security key (Yubikey), power cord and USB camera. I like that this adapter is small and has a flexible cord. You can place the adapter behind the laptop, alongside, turned outwards, etc. This makes it easier to reach the cords and when you're working on a small table. I was surprised at how much I liked this feature.I also use this when away from home and I need to plug into someone else's display setup or TV.I found that a USB wireless mouse and wireless keyboard did not work well with this adapter, but then it also didn't work well plugged directly into the MacBook, so I presume that's not the adapter's fault. I had to shift to using a bluetooth keyboard and mouse. As such, I really did not need a whole lot of ports on the adapter, this was just enough.Adapter has stayed cool. It's plugged in continuously and driving the displays about 10 hrs/day.I also liked that the style of the adapter was consistent with my MacBook.

Update2:They have finally both failed. Passthrough to the HDMI still mostly works, but the system will no longer charge. Ethernet and USB don't show. Now that I know, I wish I would have saved my money (and time) for something else.Hiearcool does not provide firmware updates, and their support is lacking.The only useful information I have found suggests that using this in conjunction with a USB switch may be causing a problem. I could understand that for bus powered switches, but mine are not.Update1:After 1.5 years of use, with one at home and one at work.If you leave the dock powered all the time, it will fail. If the external monitor has trouble getting a clean signal, or if the system fails to pull a charge, unplug the dock until it cools down.If you generate a lot of network traffic, it will overheat.To mitigate:- Don't leave the device powered when not in use.- Add an external heatsink. I can't stress enough how much this helps.- Use external powered hubs for devices that pull power.- If an external monitor won't stay on, try leaving the laptop screen on (open).- Make very sure you are using a 88W+ power adapter and capable cable.Pros:Low profile - I grabbed two of these to mount under a desk & monitor shelf. They worked great for that.Sturdy link - by using both ports, there seems to be no danger of anything coming loose. There does not seem to be an undue amount of stress put on either port.Power - I've been able to pass up to 88W of charge power through the device.Display compatibility - I have not yet found a 4K monitor that has been a problem. I have tested up to 60HzWindows compatibility - Did not seem to be an issue. I just went with whatever drivers it could find.Ethernet - The Realtek chipset is tried and true. I've not had issue.Metal Finish - Matches the "Space Gray" look perfectly.Cons:Connectivity - I had assumed the USB-C port was USB C 3.1 / Thunderbolt. It is USB 3.0 only.Slow card reader - I had assumed it wad a 3.0 reader. It is actually USB2.0Heat - It will heat up - Don't use it in an enclosed space.Fidgety on power up - I blame Apple :) - It is best, when first linking the device, to leave the laptop open. If you try to rush the initialization process, your display can get confused.USB Power Draw - High power draw USB devices should be avoided.Ground - I don't know if this is a weakness of an Apple design guideline, but MacBooks and grounding issues seem to go hand in hand. This seems to be no different with peripherals designed for macs. If you are linking to any USB device that is going to remain relatively stationary, I suggest additional grounding.Some Info:This device uses 2 TB3 ports (As USB3.1)This device has 1x USB 3.0 hub and 1x USB 2.0 hub.3.1 BUS Av3.0 Hub: 2x USB 3.0 A ports 1x USB 3.0 C port Realtek USB3 RTL8153 1GbE3.1 BUS Bv2.0 Hub: Genesys Logic USB2.o microSD Card ReaderPower: As noted, I've been able to pass up to 88W of charge power through the device.It is unclear as to which ports are associated with the HDMI or power portsLinked displays show as linked via TB3/DP.
