A MacBook Air plus two monitors is the obvious home-office setup, and it is the one most people get wrong. Apple's own support pages say the M1 and M2 Air drive one external display, and the M3 Air drives two only with the lid closed. Plug a regular two-HDMI dock into one and the second monitor stays dark or simply mirrors the first.
The docks that work around this use DisplayLink, a driver-based video chip that adds screens macOS does not drive natively. The ones that disappoint skip that chip, leave out the power adapter you then have to buy, or offer only basic 10 Gbps ports when your drives and displays want Thunderbolt speed.
We compared five docks sold for MacBook Air, from a single-cable DisplayLink dock to a five-screen trading-desk setup. One of them extends to three screens even on an M1 or M2 Air, has true Thunderbolt 4 ports, and ships with its own power supply.

Our top pickSatechi Thunderbolt 4 Multi-Display Docking Station
Checked each dock against Apple's stated MacBook Air display limits: one external display on M1 and M2, two with the lid closed on M3, two on M4 and M5
Read each listing for DisplayLink support, which is what lets a base-chip Air extend to a second monitor, and for any note that macOS only mirrors
Compared data ports (Thunderbolt 4 at 40 Gbps versus USB at 10 Gbps), SD card readers and charging wattage as stated
Recorded what is in the box, especially whether a power adapter is included; we did not run the docks ourselves

Larger desktop dock with an external power brick, not a travel hub
The long-standing fix for the Air's one-monitor limit: two 4K/60Hz monitors over HDMI or DisplayPort on any M1 to M5 Mac, 100 W charging, SD and microSD readers, and lifetime support.
Two extended 4K/60Hz monitors via HDMI, DisplayPort or both, even on Macs that natively support only one
14-in-1: front USB-C and USB charging ports, three more USB 3.0 ports, SD and microSD readers, headset jack and Ethernet
100 W laptop charging
2-year limited parts and labor warranty plus lifetime support from a North American team
USB 3.0 data ports only; no Thunderbolt 4 downstream ports
Requires the DisplayLink driver, and HDCP is not supported, so streaming services may not play on the DisplayLink screens
A compact DisplayLink dock that extends two 4K/60Hz monitors on macOS, with two HDMI and two DisplayPort outputs, 10 Gbps USB-A and USB-C, Ethernet and 100 W pass-through charging.
Extends two 4K/60Hz monitors on macOS through DisplayLink, in extended or mirrored mode
Two HDMI and two DisplayPort outputs, so most monitors connect without adapters

The maker recommends 16 GB of RAM or more for smooth multi-monitor use, and states the dock does not provide Thunderbolt functionality
No SD card reader is listed among its ports; overkill for a two-monitor desk
A strong charging hub with 160 W across four devices and 10 Gbps ports, but on macOS its two HDMI ports show the same picture, so a MacBook Air gets one extended screen.
160 W total output, with three USB-C ports at up to 100 W each
Data ports up to 10 Gbps
Two HDMI outputs for mirroring or a single extended screen
24-month warranty
The listing states that on macOS the displays on both external monitors are identical, so it cannot extend to two separate screens on an Air
No SD card reader listed, no Thunderbolt 4 ports, and no power adapter in the box
Why Satechi Thunderbolt 4 Multi-Display Docking Station is our #1 pick
Three screens even on an M1 or M2 Air
Satechi combines Thunderbolt 4 video, which macOS drives natively, with two DisplayLink HDMI ports. The listing states M1 and M2 Macs get three extended displays, which is two more than those Airs manage on their own.
Real Thunderbolt 4 ports
Three 40 Gbps Thunderbolt 4 ports mean fast external SSDs and Thunderbolt displays work at full speed. Every other dock here tops out at 10 Gbps USB.
Everything in the box
The 180 W power adapter, the Thunderbolt 4 cable and a UHS-II SD reader are all included. With two of the alternatives you also have to buy a power supply before the dock can charge your Air.
Apple states the M1 and M2 MacBook Air support one external display, the M3 supports two only with the lid closed, and the M4 and M5 support two with the lid open. If your Air is an M1, M2 or M3 and you want two monitors with the lid open, you need a dock with DisplayLink.
Two HDMI ports do not mean two screens
Plenty of docks have two HDMI ports and still only mirror on a Mac. Look for the word DisplayLink, or for a listing that says it extends two displays on macOS. Anker's dock on this page is honest about mirroring; many cheaper ones are not.
DisplayLink has two catches
It needs a free driver installed on your Mac, and DisplayLink screens usually cannot play copy-protected video such as some streaming services. For spreadsheets, code and documents it is fine; for movies, use the screen connected natively.
Check what charges the laptop
A MacBook Air needs far less than 100 W, so any dock here can charge it, but only if a power adapter is connected. Some docks include one and some do not; the UGREEN, for example, ships without.
FAQ
Can a MacBook Air run two external monitors?
It depends on the chip. Apple states the M4 and M5 Air drive two external displays, the M3 drives two only with the lid closed, and the M1 and M2 drive one. With a DisplayLink dock, any of them can extend to more.
Do I need a Thunderbolt dock for a MacBook Air?
Not for two monitors; a USB-C DisplayLink dock like the Plugable does that. Thunderbolt matters if you use fast external SSDs or Thunderbolt displays, or want the most screens from one cable.
Will DisplayLink slow down my Mac?
It uses some processing power to drive the extra screens. For office work most people do not notice. The WAVLINK five-screen dock's maker recommends 16 GB of RAM for its largest setups.
Does a docking station charge the MacBook Air?
Yes, through the same cable, as long as the dock is powered. Check whether the power adapter is included; Satechi and WAVLINK include one, UGREEN and Anker do not.
Bottom line
For a MacBook Air desk with two or more monitors, the Satechi Thunderbolt 4 dock is the one to buy: three screens even on an M1 or M2 Air, real Thunderbolt 4 ports, and the power adapter in the box. If you only need two monitors and ordinary USB ports, the Plugable DisplayLink dock does that job on any Air for less.
