Feature Packed





  • Up to 60W of USB Power Delivery

If your device supports USB Power Delivery (USB PD), this docking station supports up to 60 watts (60W) of charging to your host device.

This means you won’t need to use the charger that came with your laptop when you’re at your desk, on supported hosts. The one USB-C cable from the dock is all you’ll need to stay charged and connect all your devices.

Some laptops may require more power than this dock provides (60W). The Dell XPS 15 9550/9560 and Precision 5510/7510, for example, will display a warning during boot if connected to a 60W power adapter, rather than a Dell 130W power adapter. These systems may still charge, but at a slower rate, and may use battery power when under heavy load.


  • 1x HDMI (Alt Mode)
  • 2x HDMI (DisplayLink)

With one USB-C (USB Type-C) cable connected to the dock, overcome the limited number of display outputs and ports on your device. This dock connects up to three HDMI displays on supported devices.

HDMI 1 supports resolutions up to 4K 30Hz. HDMI 2 and HDMI 3 support resolutions up to 1920×1200 @ 60Hz each

For USB-C ports that do not support Alternate Mode video output will be limited to displaying through the two DisplayLink HDMI ports.

Note: HDMI can be adapted to DVI or VGA with separate adapters or cables, but is incompatible with DisplayPort inputs on displays.


  • 6x USB 3.0 Ports
  • 1x Gigabit Ethernet*
  • 1x 3.5mm TRRS Headset Port**

Many laptops are removing or drastically reducing the number of ports available.

Get back your USB, audio, and network connections. This dock also makes it easy to leave your peripherals plugged in at your main work area, and reconnect them, with one cable from the dock.

* Network driver in macOS currently supports 200-300Mbps

** TRRS Headset port supports stereo headphones and mono microphone on a single 3.5mm four-conductor connector, additional adapters may be necessary to connect some headsets with separate stereo headphone and microphone connections.

Hardware Compatibility Notes

USB-C is a new standard with much versatility. As a result, compatibility information is complex. Some USB-C systems support Alt Mode video output, while others do not.

Port Features, Limitations, Notes, and Terminology

USB-C Alternate Mode (Alt Mode) is a new feature introduced with USB 3.1, allowing USB-C ports and cables to carry video signals directly from a device over a USB cable. Alt Mode video comes directly from the graphics card or integrated graphics processor on a device, meaning outputs from an Alt Mode video port have the full graphics acceleration of your system. Not all systems with USB-C support this functionality.

HDMI 1 (Alt Mode) allows for a maximum output resolution of 4K 30Hz (3840×2160 @ 30Hz). Lower resolutions such as 1920×1200, and 1920×1080 (1080p) are supported at 60Hz. The HDMI 1.4 connection on this dock is provided by converting DisplayPort Alt Mode to HDMI 1.4.

HDMI 2 and 3 (DisplayLink) allows for a maximum output resolution of 2K 60Hz (1920×1200 @ 60Hz). The HDMI 1.3 connection on this dock is provided by the DisplayLink DL-3900 USB graphics chipset.

DisplayLink is a technology that allows compressed data of various types to be sent over USB data connections. The DisplayLink DL-3900 chipset in this docking station connects all the data and video connections, other than the “4K” HDMI 1.4 connection, on this dock.

There are a few important limitations of DisplayLink technology. DisplayLink uses a proprietary compressed video stream that is partially generated by both your computer’s CPU and GPU, and is a “virtual” video adapter. Because the video is compressed and packetized as data, then reassembled by the DisplayLink chip, the pacing of new frames of video can be inconsistent, particularly if large portions of the content being sent through DisplayLink is changing (such as with video playback).

Because of how DisplayLink provides video, video outputs provided by DisplayLink technology should only be used to display content like office applications and web browser windows, not games or video content.

HDCP is not supported, this means protected content such as Netflix, Amazon Video, YouTube Premium, Hulu, Blu-ray videos, and other protected content, either may not work or will play at a lower resolution, depending on the content provider.

Some USB-C ports Windows Laptop computers are labelled as Thunderbolt 3 ports. Thunderbolt 3 ports are USB-C ports with additional functionality that are also compatible with this docking station.

USB-C Power Delivery (USB-C PD) is a standard introduced with USB-C that provides enough power for many mobile devices and laptops. This dock is able to supply up to 60W of power to a host. Some laptops may require more power than this. The Dell XPS 15 9550/9560 and Precision 5510/7510, for example, will display a warning during boot if connected to a 60W power adapter, rather than a Dell 130W power adapter. These systems may still charge, but at a slower rate and the battery may discharge under heavy system loads.

  1. Moises

    Works with M1 MacBookWorks with the 2020 M1 MacBook Air. It is not plug-and-play. You do need to go through steps to set up which is fine with me but some people might have difficulty with it. The only thing that stops it from being a 5-star is that it is not perfect. When the computer sleeps or you are initially connecting it takes some time to recognize all three monitors or sometimes it won’t recognize one and I have to turn off my monitor and on again to recognize it. However, it gets the job done. But for this price point, I think it should be a bit more flawless. I currently have 2 1080p monitors and one 32″ ultrawide monitor which to my surprise it has been pretty reliable a couple of hours in. No lag is noticeable. I have not tried the Ethernet port. Charges the computer and no overheating. Overall, 4.5/5 stars. Great product to bypass Apple’s one monitor functionality with M1.

  2. J_Snell

    Does The Job For 2020 MacBook AirI started out aiming for small and portable USB-C to USB/HDMI hubs, got a SATECHI based on reviews, 2 weeks in and was disappointed, so back to looking for a solution for my MacBook Air – with Apple Chip, and this Plugable kept coming up. Pricey, but so far – WORTH IT. Devices plugged in stay recognized by the laptop and charging is passing through consistently, without overheating issues. I’ve only gone with the 2 monitor set up so far, but it worked right out of the box without issue. My only real gripe is the thing is big, so portability this isn’t, but it gets the job done while working from home, and that’s what I need it for mostly.

  3. KnightTrader

    Easy to use, worked right from the box after installing driversSupported my three HDMI monitors with ease from my ASUS gaming laptop. Lightweight to my surprise, but very durable.

  4. Marvin McLain Jr.

    Great Docking StationI definitely recommend the products made by this company. Docking station is easy to setup and use. Love the fact I am able to attach my USB devices to this dock and all I have to do is move one cord to change between my work and personal laptops and still have multiple screens at my disposal.

  5. Shaheem Litchmore

    Works great with the new MacBook Pro M1Was looking for a hub that worked with my new MacBook Pro M1. After a few failed attempts, this hub is perfect. Works right out of the box no hassle.

  6. Daniel

    Great Value!This is a great product. I swap from an older model that had some issues with image definition and screen flickering. I have two full HD monitors, different brands, and the definition in one of those was not full HD, I could see the pixels! I thought it was the brand (cheap brand, popular on Amazon) and I was considering returning it. This product improved image definition on both monitors. Only drawback is transfer speed of usb ports, but that is an issue I found out all docking stations have.

  7. Charles Olcott

    Great productivity and multitasking toolI picked this up for more of a test case than anything, but it works wonderfully for almost everything (more on that in a min). Just downloaded the drivers onto my GS66 laptop, plugged it into the Thunderbolt connection, and my monitors into the Plugable, and up and running in no-time. For any standard work, it works great. Drag and drop windows, multitask, everything just works, and the 6 USB ports are a great bonus. All for less than the price of the standard manufacturer offerings.Gaming IS possible, but with a big caveat – There’s going to be a slight split-second timing space between the monitors. I actually wanted to test to see if I could set up a triple monitor setup for iRacing, even though it isn’t advertised to be used as a gaming unit. It does work fine, but with just the slightest off-sync between my outer monitors and the center which I have set up as the “main” monitor in the first port. I actually didn’t expect it to work nearly as well as it does though, which is just another testament for how well it does perform. Definitely worth it, even more for people who need it for productivity and multiple window support!

  8. Peter A. Eisch

    Good, Desktop DockI use this as a USB hub and without connecting any video. Its been a couple weeks and works fine with my 2018 MacBook Pro.

  9. Amazon Customer

    Overall works great with few glitchesDoes support 3 monitors, setup was easy needed drivers loaded to get all monitors working. Only issue I am having thus far is when plugging in more than 2 USB devices to the docking station, it caused the monitors to go off and then come back on, sometimes all three monitors come back on, sometimes only one…have not been able to determine why at this point. Other than that issue, very satisfied with the docking station.

  10. Tim Gamble

    Great product for M1 Mac usage. NOT for new iMac M1I’ve purchased and installed three of these. They work great with the new M1 MacMini and Macbook Air’s that I have them paired with. However they DO NOT work with the new M1 iMac. At first it was working but after 24 hours it no longer works. In fact it smells like burning electronics. I tried another brand new one and it didn’t work at all. However works fine with my Macbook air. Maybe it’s just my M1 iMac but using an Apple branded HDMI/USB dongle works fine, nothing else. Maybe Apple did this to push you to buy more of their devices. Idk…
