Best USB-C Hubs and Adapters for MacBook and Mac 2025

9 Ports: 2x USB-C, 3x USB-A, HDMI, Gigabit Ethernet, SD Card Reader, MicroSD Card Reader, 125W laptop charging

This 9-in-1 hub is bristling with top-end ports and—with an unrivaled 125W of laptop passthrough power—is a great match for larger laptops.

A seven-inch cable connects the hub to your MacBook at 10Gbps and a possible 125W passthrough charging when the hub is connected to a USB-C charger—the highest passthrough charging we’ve seen in a USB-C hub. Total power output from the hub to laptop and devices is 140W.

There’s one dedicated 10Gbps USB-C data port, HDMI 2.0 port with 4K 60Hz support, and both SD and MicroSD card readers at fast UHS-II media-transfer speeds. If you need to attach legacy devices there are two USB-A ports, also at 10Gbps. One of these can drive 7.5W of power to the connected device. There’s also a much slower 480Mbps USB 2.0 port that good for a memory stick or mouse/keyboard.

With its extra USB-A port and faster SD card readers, the 9-in-1 Plugable USB-C Hub beats our long-time USB-C hub champ, the Anker 555 8-in-1 USB-C Hub, reviewed below. If you prefer DisplayPort to HDMI the Anker 565 should be considered even with its slower card readers.

8 Ports: 2x USB-C, 2x USB-A, HDMI, Gigabit Ethernet, SD Card Reader, MicroSD Card Reader, 85W laptop charging

The Anker 555 USB-C 8-in-1 Hub is compact and powerful, offering greater specs than some of the other leading options on this list. It’s one of two similar USB-C hubs from the company, and we start with the best-value option.

The 555 offers two USB-C ports—one that supports 85W USB-C Power Delivery, while another supports data transfers up to 10Gbps. You also get speedy 10Gbps transfer rates through two additional USB-A ports, where many rivals max out at 5Gbps. 

The Anker 555 is special as it offers an HDMI port that supports 4K 60Hz resolutions, where most are limited to 4K 30Hz. For 4K 60Hz resolution, your device must support DP 1.4. This includes MacBook Air (from 2020), MacBook Pro 15in (from 2018), MacBook Pro 16in (from 2019) and iPad Pro (from 2018).

Also included are SD and MicroSD card reader slots. These are rated at UHS-I (104MBps) so not the fastest. If you transfer a lot of data via SD cards, look for a hub with faster UHS-II (312MBps).

The Gigabit Ethernet port is great for those times when Wi-Fi just won’t do.

It’s also incredibly light at just under 4.5oz (130g) and compact so you can take it anywhere. At $49.99 / £79.99 it’s hard to deny this hub’s value for money. In our experience, it does get warm with use but Anker says this is normal.

Anker

The higher-end $65.99 / £89.99 Anker 565 USB-C Hub, shown above, offers eleven ports instead of the 555’s mere eight, and is equally lightweight at 4.8oz (136g). The extra ports are one USB-A and an audio jack, which isn’t a remarkable boost—but it does include a top-end DisplayPort 1.4 video connection in case HDMI is not for you. If the inclusion of a native DisplayPort is important to you, then the 565 is a better solution (read our full Anker 565 11-in-1 USB-C Hub review) than maybe even the Plugable 9-in-1 reviewed above.

5 Ports: 1x USB-C, 4x USB-A

If all you need from an adapter is the ability to connect a bunch of older USB-A devices to your MacBook, this simple adapter should do the trick.

The Ugreen USB-C 4-port hub is a slim and inexpensive adapter that allows you to add four full-size USB 3.0 ports that can handle data transfer at up to 5Gbps. It has recently been upgraded to feature a further USB-C port that can supply a 10W charge for connected devices, but not the host computer. While all four ports can be used simultaneously, a maximum of two hard drives can be connected at one time.

It looks the part with most modern MacBooks, and is an easy way to connect memory sticks, a printer or other older devices that don’t come with USB-C.

1 Port: 1x USB-C to USB-A

There’s a misconception that USB-C is an inconvenience for people with a bunch of devices still reliant on USB-A, hence the existence of little adapters like this one from Nonda. Products like this are there to help us bridge the gap.

This cute little adapter is simply to allow you to plug in one standard USB-A device or cable at a time, great for using a USB stick, for example. Just don’t misplace it—it’s tiny.

5 Ports: 4x HDMI, 1x USB-C passthrough charging

There are many USB-C hubs with more than one HDMI port but most are restricted to Mirrored Mode (where all external screens show the same image as on the MacBook) or in only partially Extended Mode (where the external displays show a different image to the MacBook but are the same themselves). That’s a Mac limitation only, not the fault of the hubs themselves, which work fine for Windows. Blame Apple.

Using DisplayLink software—a simple download—the Plugable USB-C Quad 4K HDMI Adapter (USBC-7400H) can support four 4K external displays, all showing a different image to the MacBook and each other—so full Extended Mode. It also features 100W passthrough USB-C charging. See below this list of hub recommendations for a graphic showing the differences between Mirrored and Extended Modes on the Mac.

Plugable

If you need only two external displays in full Extended Mode, the $89.95 / £109.95 Plugable USB-C Dual HDMI Adapter (USBC-6950M) shown above features two HDMI ports but no passthrough charging.

7 Ports: 2x USB-C, 1x USB-A, HDMI, Gigabit Ethernet, SD Card Reader, MicroSD Card Reader

All of the portable USB-C hubs reviewed here are compatible with the Mac’s Thunderbolt 3, 4 and 5 ports, but most feature slower USB-C connections (5Gbps or 10Gbps) compared to Thunderbolt (40Gbps for TB3 and TB4, and 80Gbps with TB5).

The Satechi Pro Hub Max, available in either Silver or Space Gray, features USB4 ports that are both compatible with Thunderbolt and can reach the same 40Gbps maximum throughput.

Connecting directly to two of the MacBook’s Thunderbolt ports, it boasts a bunch of ports that should be enough for most of us. The hub receives 40Gbps from each of the Thunderbolt ports on the Mac (so a total of 80Gbps). 40Gbps is used for the USB4 pass-through port, while the second Thunderbolt port distributes 40Gbps of bandwidth to the rest of the ports on the hub.

The USB4 port supports up to 96W charging—easily fine for a 14-inch MacBook Pro and punchy enough to keep a 16-inch Pro going and charged pretty quickly. This same USB4 port can be used to connect to an external display—up to 6K at 60Hz display output, transferring data at 40Gbps.

It should allow video output and passthrough charging simultaneously. In a test connection from a MacBook to an LG 4K UltraFine Display, the MacBook was able to output video to the monitor, while the monitor was able to provide power to the MacBook, all through the single connection. Owners of the 14- and 16-inch MacBook Pro and M2 Air can charge via the MagSafe connector at the same time as using the Pro Hub.

The HDMI 2.0 port can also be used to connect a 4K 60Hz display, so you can achieve a dual 4K monitor setup on any Pro or Max M1 or M2 MacBook. Plain M1/M2 MacBook Airs are limited to just one external display.

Also onboard are a 5Gbps USB-A port and a 5Gbps USB-C port—although neither can charge connected devices. There are both SD and MicroSD card readers (UHS-I), a Gigabit Ethernet port, and 3.5mm combo audio jack port.

In the same family, Satechi also offers the Pro Hub Mini (the same as the Max but without the HDMI port) and the Pro Hub Slim (which swaps the Ethernet port for an extra USB-A port, and boasts 10GBps USB-A and USB-C ports compared to the Mac and Mini’s 5Gbps). If you don’t need wired Internet access, the Pro Hub Slim edges out the Pro Hub Max. If you don’t need more than one external screen or you want to save the USB4 for passthrough charging only, consider the Pro Hub Mini or the Plugable 5-in-1 USB-C Hub reviewed below..

Note that all three requires a MacBook with two adjacent Thunderbolt ports on one side.

5 Ports: 1x USB-C, 2x USB-A, HDMI, Gigabit Ethernet, Audio jack

While not certified as either USB4 or Thunderbolt 4, this compact and very portable 5-in-1 USB-C hub (AMS-5IN1E) offers 40Gbps data-transfer via its USB-C port, and is designed for the 14-inch and 16-inch MacBook Pros introduced after 2021, or MacBook Airs introduced after 2022. A smart cutout keeps access to those MacBooks’ MagSafe charger port.

The inclusion of the 40Gbps USB-C port is useful as the hub uses the two Thunderbolt or USB4 ports in its flush side connection to the MacBook. But, in return, it gives you two 5Gbps USB-A ports (4.5W charging) and Gigabit Ethernet. The audio jack port is also covered but replicated on the hub.

The 40Gbps USB-C port can be used to connect a display up to 6K at 60Hz, or offer passthrough charging at up to 100W—15W for phones and other devices.

Its closest rival is the Satechi Pro Hub Mini (reviewed above), which features an extra USB-C port (5Gbps) but is more expensive, so this hub wins our budget 40Gbps hub award.

6 Ports: 2x USB-C, 2x USB-A, HDMI, Gigabit Ethernet

We are big fans of the Baseus 6-in-1 USB-C Hub which lacks the card readers found on some hubs but boasts three 10Gbps USB ports (2x USB-A and 2x USB-C) and Gigabit Ethernet, plus an HDMI port that supports an external display at 60Hz. It also features a button that will quickly turn the connected external display off.

Baseus has several other excellent and affordable USB-C hubs, one of which might suit you better, so check out what each offers:

Baseus 7-in-1 USB-C Hub: 100W passthrough charging; 1x HDMI (4K@60Hz); 3x USB A (5Gbps, 7.5W charging), SD and MicroSD card readers via Amazon US and Amazon UK.

Baseus 8-in-1 USB-C Hub: 100W passthrough charging; 1x HDMI (4K@30Hz); Gigabit Ethernet; 3x USB A (5Gbps, 7.5W charging), SD and MicroSD card readers via Baseus and Amazon.

Baseus 9-in-1 USB-C Hub: 100W passthrough charging; 2x HDMI (one at 4K@120Hz; other HDMI can only mirror the display on Macs at 4K@30Hz); Gigabit Ethernet; 3x USB A (two at 5Gbps and one at 480Mbps), SD and MicroSD card readers via Baseus and Amazon.

Each hub includes an integrated USB-C cable that can be minimized for travel with its neat cable-tidy port that creates a loop. And there’s an LED that shows you when the the hub is in use.

8 Ports: 5x USB-C, HDMI, Gigabit Ethernet, SD Card Reader

This USB-C hub has four USB-C ports but no USB-A. If you no longer have need for old-time USB-A by buying this hub you won’t be wasting money on a port you don’t require. If you have USB-A peripherals, such as an older memory stick, then you should look for a hub with a Type-A USB port.

Three of the USB-C ports offer fast 10Gbps data transfer, and one at 5Gbps. A fifth USB-C port is for attaching a power source, most likely a USB-C wall charger. If the charger is rated at 100W, all that power can be distributed via the hub, including up to 85W PD to the host laptop or tablet.

However, aside from the pass-through PD port, none of the USB ports can output power to connected devices.

The EZQuest USB-C Slim Gen 2 Hub Adapter 6-in-1, reviewed here lower down, has four 10Gbps USB-C ports, each with 7.5W device charging, plus two more for 4K/60Hz monitor support and 80W passthrough charging, but it lacks the Ethernet and card reader.

And the SD card reader is also top-notch at 312MBps, compared to some that are UHS-I at 104MBps.

Despite the 8K in its name, the HDMI 2.1 port can support only as high a resolution as an external 4K display at 60Hz refresh rate, as well as display options of 2K/144Hz and 1080p/240Hz. Apple display limitations mean that its potential 8K/30Hz display support is limited to Windows machines.

It’s at the high end for price but you get high-end, premium and future-proof ports for your money.

It is available in Apple MacBook-matching Space Gray, Silver, and Midnight colors.

1 Port: 5Gb Ethernet

For even faster speeds when connected to a supporting network, this one-function adapter adds an inexpensive route to 5Gbps Ethernet. It’s simple yet effective if you need more ports, you’ll pay more for such fast network speeds.

It’s backwards compatible with 1Gb and 2.5Gb networks, so is more future proof than a 2.5Gb adapter if you are always after the fastest data transfers.

The cable is short at 4.7 inches (12cm) but you shouldn’t need any longer for a network adapter.

If you want fast Ethernet but more ports, check out some of the Satechi hubs also reviewed here. Plugable also offers a USB-C to 2.5GbE Adapter, listed lower down this list.

6 Ports: 6x USB-C

This USB-C hub loves USB-C so much that it boasts only that type of port, of which there are six—seven if you count the connector that links to the laptop.

Four of these are rated at 10Gbps for data transfer, which is about as fast as you can get before you have to switch up to 40Gbps Thunderbolt.

Another can link up to an external display up to 4K in resolution and at a action-screen-friendly 60Hz refresh rate. You can either connect direct to a USB-C monitor, or use a USB-C to either DisplayPort or HDMI adapter.

The sixth USB-C port can handle 100W of PD 3.0 power input, 80W of which is reserved for the MacBook if it needs that much. Each of the 10Gbps ports can deliver 7.5W, up to a maximum 15W across all four at the same time.

4 Ports: 2.5Gb Ethernet, 3x USB-C

There are hubs with more ports but this 4-in-1 USB-C hub offers three fast 10Gbps USB-C ports and very fast 2.5Gb Ethernet.

The Satechi USB-C Multiport Adapter 8K With Ethernet V3, reviewed above, boasts more functionality but at twice the price and with standard 1Gb Ethernet. The Satechi 4-port USB-C Hub, reviewed below, offers an extra USB-C port but none at 10Gbps, and no 2.5Gb Ethernet.

This hub could be in your sweet spot if you need a bunch of fast USB ports and faster Ethernet. There’s no passthrough charging, so you’ll need a spare Thunderbolt port on your MacBook for power.

4 Ports: 10x USB-C charging ports

This multi-port hub is not for data transfer but is the best for charging multiple USB-C devices up to 100W utilizing clever priority-charging technology that distributes power across all connected devices—prioritized in the order you choose from left to right. As devices reach full charge, the now greater available power is reallocated down the line.

The Plugable PS-10CC can neatly and efficiently charge up to 10 hungry devices at the same time and at an optimum power distribution without you having to resort to multiple chargers and a desk full of indistinguishable snaking cables.

Ten is a lot of devices so Plugable has followed up with a smaller, cheaper model, the PS-6CC that can charge up to six devices in the same manner.

4 Ports: 4x USB-C

Sick of hubs that still think USB-A is a thing? If what you want is more USB-C ports, the Satechi 4-Port USB-C Hub has plenty for you. Each port is USB-C 3.2 Gen 1 so 5Gbps, although that should be fast enough for most. If not, look no further than the EZQuest USB-C Slim Gen 2 Hub Adapter 6-in-1 reviewed above with its four 10Gbps USB-C ports plus passthrough power and video USB-C ports.

The USB-C ports don’t support passthrough charging or video output, and can handle only two hard drives or SSDs at the same time.

7 Ports: 2x USB-C, 5x USB-A

If it’s just USB ports you need to add, then you find more than enough on Startech.com’s 7-Port USB-C Hub, although we’d have preferred more USB-C ports, which here are outnumbered by legacy USB-A.

There are five USB-A ports, all rated at a speedy 10Gbps, with one offering 12W of device-charging power. One of the two 10Gbps USB-C ports can also charge connected devices at 12W. The other USB ports each offer a small charge of 4.5W.

Even 12W is not powerful enough to fast charge an iPhone but it’s enough to keep most connected devices powered up.

The hub is self-powered via its 65W power supply.

10 Ports: 2x USB-C, 2x USB-A, 2x HDMI, Gigabit Ethernet, SD Card Reader, MicroSD Card Reader, Audio jack

This hub has enough different ports to call itself a docking station. It has two HDMI ports, two USB-C ports (one PD and one 5Gbps), SD/microSD/SD readers (UHS-I), two 5Gbps USB-A ports, a 3.5mm audio combo jack for headphones, and Gigabit Ethernet.

It doesn’t have its own power supply but offers passthrough PD charging at a more than healthy 100W.

It’s a great set of ports, but that’s not it’s biggest plus for users of Apple’s plain M1/M2/M3-based MacBooks.

The standard M1 and M2 chips (that is non-Pro/Max) in Apple’s MacBooks are powerful but have a major limitation: unlike Intel-based Macs, they don’t support more than one external display. The plain M3 MacBooks can connect two displays but only if the MacBook’s lid remains closed. The smarter M4 and M1/M2/M3/M4 Pro and Max chips do support multiple displays.

If that is a problem for you there is a hardware solution in the Hyperdrive Dual 4K HDMI 10-in-1 USB-C Hub, which lets non-Pro/Max Macs connect two external displays. There is some light software installation involved for M1/M2/M3 users, and you need to allow InstantView access to your Privacy settings in System Preferences. There are alternative solutions for adding two or more monitors to an M1, M2, M3 MacBook.

One HDMI port allows for 4K at 60Hz, and the other 4K at 30Hz. If you want two or more 4K screens at 60Hz and are willing to do without the extra USB ports and so on, look at the Plugable Quad and Dual 4K HMDI adapters reviewed earlier in this article. These are cheaper and offer superior display specs.

6 Ports: 2x USB-C, 1x USB-A, HDMI, 2.5Gb Ethernet, Audio jack

If you want the fastest Internet and network speeds, you need to push past Gigabit Ethernet to Multi-Gig Ethernet, ranging up to 10Gbps. This six-port hub from Satechi boasts a 2.5Gbps (2.5GbE) Ethernet port—2.5x faster than regular Gigabit Ethernet. 2.5GbE development is becoming more commonplace now that WiFi 6 enables wireless connection to over 1GbE LAN, and you can find 2.5G ports on some WiFi 6 routers. Current CAT5e Ethernet cables are compatible so there’s no need for rewiring.

Aside from this super-fast Ethernet this hub boasts 4K at 60Hz HDMI, 10Gbps USB-A and two 10Gbps USB-C ports (one with 100W passthrough charging) and a combo 3.5mm audio jack. Note that neither USB-C port supports video transfer so it’s a one-display hub.

This hub also stands apart from standard USB-C ports by being USB4, which means you get to play with your Mac’s full 40Gbps Thunderbolt 4 bandwidth.

If all you need is the 2.5Gbps (2.5GbE) Ethernet port, look at Satechi’s more affordable USB-C 2.5 Gigabit Ethernet Adapter, which boasts a strong braided cable.

1 Port: 1x USB-C, 2.5Gb Ethernet

If all you need is a USB-C adapter that will add super-fast Ethernet to your computer, the Plugable USB-C to 2.5Gb Ethernet Adapter offers 2.5x network speeds compared to standard Gigabit Ethernet on supporting networks. A side USB-C port offers 100W passthrough charging to the laptop.

The short cable isn’t braided like the £39.95 Satechi USB-C 2.5 Gigabit Ethernet Adapter but the adapter is cheaper and just as able.

U.K. customers may find the Ugreen USB-C to Ethernet Adapter 2.5G cheaper, although it lacks the laptop passthrough charging.

3 Ports: 1x USB-C, 1x USB-A, 1x HDMI

Apple got a lot of flack when moving to USB-C because it meant that many of its users had to buy one or more adapters to replicate the ports they were used to, and needed.

It wasn’t so much that we needed adapters, but more to do with the price Apple was charging for its simple USB-C hubs and adapters.

Take, for example Apple’s USB-C Digital AV Multiport Adapter, which at $69 is a lot for just an HDMI port, one USB-A port and a passthrough-power USB-C port.

Plugable has a much cheaper alternative, at about a third of the price. And it looks pretty identical.

Aside from the price, the one drawback shared with the Apple version is that the HDMI connection can connect a 4K external display at 30Hz rather than the full 60Hz, which may put off gamers.

But otherwise, this is a great alternative at a fraction of the price, and can charge at 60W.

4 Ports: 3x USB-A, SD Card Reader

We tend to think of hubs for laptops, such as Apple’s MacBooks, which lack more than one or two USB-C ports and so require a dock to add further devices. The Mac Mini and Mac Studio, you’d think, have an army of ports in comparison to Apple’s laptops.

Apple’s latest M4 Mac mini does at least add a couple of USB-C ports and an audio jack at the front—sadly lacking for its earlier M1 and M2 Mac mini models, see below—but it doesn’t have any legacy USB-A ports or card readers.

The Satechi Stand & Hub for the M4 Mac mini adds three USB-A ports—two at 10Gbps and one at 480Mbps—at the front, plus an SD card reader. Inside the Hub is an enclosure that enables you to add an NVMe SSD—so adding more hidden storage at prices much cheaper than offered by Apple at purchase.

It fits neatly under the mini and, in our tests, didn’t suffer the same Wi-Fi problems as its M1/M2 sibling, although it has three fewer ports.

7 Ports: 1x USB-C, 3x USB-A, SD Card Reader, MicroSD Card Reader, Audio jack

Before Apple miniaturized the Mac mini even further in 2024, the 2018-2023 Mac mini models boasted two Thunderbolt 3 / USB4 (fast USB-C) ports, two old-school USB-A ports, HDMI 2.0, Gigabit Ethernet, and 3.5mm headphone jack. That sounds like a lot, but Apple accessory specialist Satechi believes the Mini needs maxing.

Satechi’s Type-C Aluminum Stand & Hub for Mac Mini expands these capabilities with seven ports: including a USB-C data port, three USB-A ports, micro/SD card readers, and another 3.5mm headphone jack port. (Note that you can’t charge devices connected to the USB ports, as they are there for syncing and data transfer only.)

The crucial point is that these points are front-facing, and not tucked around the back with the unwieldy and unsightly power supply. It also lifts the Mini off the desk, and its built-in air vents help regulate temperature and encourage airflow.

There is a superior model, the Satechi Stand & Hub For Mac Mini / Studio With NVMe SSD Enclosure, which includes an integrated slot where you can insert an SSD card to add affordable fast storage, accessible when connected to your Mac mini or Mac Studio. Read our Satechi Stand & Hub With SSD Enclosure review.

Both of the Satechi M1/M2 Mac mini Stand Hubs, however, can have a negative impact on the mini’s Wi-Fi signal strength, so it’s recommended to use the wired Ethernet option instead.

In spring 2025 Satechi will start selling a version of the hub for the smaller 2024 Mac Mini M4, with up to 4TB NVMe storage and 10Gbps USB-C. Apple has added USB-C ports to the front of its new Mac mini but Satechi’s hub will add USB-A and a card reader. We will review the new Mac Mini M4 Stand & Hub with SSD Enclosure (pictured above) when it is released.

6 Ports: 2x USB-C, 1x USB-A, 1x HDMI, SD Card Reader, MicroSD Card Reader

You might not think a desktop Mac needs a hub, but the 24in iMac is quite lacking, having either just two Thunderbolt ports on the entry-level model or two Thunderbolt and two USB-C at the top-end. These ports are also all hidden away at the back, which can mean snaking cables all over your desk.

Five of the ports on this hub that clamps to the underside of the iMac are front-facing ports for easy access to memory cards, USB storage, or storage cards. There are two USB-C ports and one USB-A port (all rated at a speedy 10GBps). The USB-A port can charge a phone at 7.5W.

The UHS-I (104MBps) SD and microSD card readers aren’t the fastest but should suffice. Such memory cards are an affordable way of adding portable storage, and will also delight camera users.

At the rear of the hub is an HDMI port that can support an external 4K display at 60Hz.

Hyper also sells a 5-in-1 iMac USB Hub with two USB-C (5Gbps) and three USB-A (5Gbps and one that charges at 7.5W).

Quite brilliantly, the hubs can color-match with your 24in iMac, with 7 iMac color faceplates included.

6 Ports: 1x USB-C, 3x USB-A, SD Card Reader, MicroSD Card Reader

While not as colorful as the HyperDrive 6-in-1 USB-C Hub, this USB-C hub for the 24-inch iMac offers a set of basic ports slung under the iMac screen at a slightly lower price.

It brings four USB ports within easy arm’s reach, so you don’t need to fiddle around at the back of the computer.

It lacks the HyperDrive’s HDMI port but gains an extra USB-A port, although at a slow 480Mbps and with little charging power.

1 Port: SD Card Reader

If you’re a digital professional or just a photography enthusiast, chances are you might be slightly peeved that the new MacBook Pro you held out for doesn’t have an SD card slot. 

SanDisk is here to save the day. This neat SD card reader is USB-C compatible and will allow Thunderbolt 3 speed transfers of all your high-resolution photos and videos. 

SD cards are also a very inexpensive way to add portable storage to your laptop, from 32GB up to 1TB.

2 Ports: HDMI, VGA

This simple adapter makes a USB-C port into a VGA port for older displays and projectors, and also can handle two external displays.

VGA was once the most popular video connector but is seen less these days, being overtaken by DVI, HDMI, DisplayPort and direct USB-C.

It supports 920×1200@60Hz HD resolutions via VGA, and 4K at 30Hz through its HDMI port. It isn’t compatible with supporting two displays on an M1 MacBook.

1 Port: DVI

If you need to connect to a DVI (Digital Visual Interface) display or projector, this adapter does the trick. 

It can support resolutions up to 1,920-x-1,080 at 60Hz.

1 Port: Thunderbolt 2

This adapter is designed to help owners of really quite old Macs smoothly transition to using USB-C. You may well have devices such as hard drives and external displays that use Thunderbolt 2 connections. This little gadget lets you keep using them with your MacBook or new MacBook Pro.

It also allows new Thunderbolt 3, 4 and 5 devices to connect to a Mac with Thunderbolt 2 ports–but to take advantage of it this way round Apple advises you need to be running macOS Sierra or above.
