Anker 778 Review 2026 - Specs, Pros & Cons

Name: Anker 778 Thunderbolt Docking Station (12-in-1, Thunderbolt 4)
Brand: Anker
SKU: A83A9

The Anker 778 is a 12-in-1 Thunderbolt 4 dock built mostly for Windows laptops that need several external displays from one cable. It has a 100W upstream Thunderbolt 4 host connection, one downstream Thunderbolt 4 port, two 10 Gbps USB-C ports with 30W charging, two 5 Gbps USB-A ports, two USB-A 2.0 ports, Gigabit Ethernet, HDMI 2.1, and two DisplayPort outputs. Anker's official spec sheet says it can run one 8K display at 30Hz or up to four 4K displays, with a 180W power adapter included in the box. That makes it a strong desk dock for Windows users with several monitors and a laptop that can take advantage of Thunderbolt 4 bandwidth. The tradeoff is compatibility. Anker says the dock requires a Thunderbolt 4 port and is not compatible with M1 or M2 MacBooks or Asus laptops with AMD CPUs. Reviewers also call out that Mac display behavior is limited, and that the dock has only one downstream Thunderbolt 4 port, no card reader, and no audio jack. If your setup is a Windows laptop plus two to four displays, the 778 makes sense. If you use a MacBook or need more downstream Thunderbolt ports, look elsewhere.

Best Anker Thunderbolt 4 dock for Windows multi-monitor setups

Pros & Cons

What We Like

100W host charging is enough for most business and creator laptops
HDMI 2.1 plus two DisplayPort 1.4 outputs make multi-monitor Windows setups easier
Two front USB-C ports support 10 Gbps data and 30W charging each
Officially supports one 8K display or up to four 4K displays on capable hosts
Includes a 180W power adapter and 0.7m Thunderbolt 4 cable

What Could Be Better

Poor fit for Mac users, especially M1 and M2 MacBooks
Workaround: Choose a Mac-friendly Thunderbolt 4 dock such as the CalDigit TS4 or Kensington SD5700T instead.
Expensive at the normal $379.99 price
Workaround: Wait for a sale. PCWorld says the dock is much easier to recommend below $250.
Only one downstream Thunderbolt 4 port limits daisy chaining
Workaround: If you need several Thunderbolt accessories, pick a dock or hub with three downstream Thunderbolt ports.
No SD card reader, microSD reader, or audio jack
Workaround: Add separate USB adapters, or choose a dock with built-in creator ports.
Rear USB-A 2.0 ports are fine for keyboards and mice but slow for storage

Display Support

Max Displays: 4

Compatibility

Windows (10+)

Best fit for Windows laptops with Thunderbolt 4. Quad-display support depends on the laptop GPU and Thunderbolt implementation.

macOS

Mac support is limited. Anker says M1 and M2 MacBooks are not compatible, and reviewers found Mac multi-display behavior weaker than on Windows.

Known Issues

M1 and M2 MacBooks

Not compatible according to Anker

Asus laptops with AMD CPUs

Not compatible according to Anker

USB-C only laptops without Thunderbolt 4

Unsupported host connection

Mac users who need extended multi-display support

Poor fit for the display layout

7.8 /10

Our Verdict

Very Good

The Anker 778 is a very capable Thunderbolt 4 dock, but it is not the safe default pick for everyone. The good parts are obvious: 100W laptop charging, two front USB-C ports that can each deliver 30W, three dedicated video outputs, one downstream Thunderbolt 4 port, and enough USB-A for older peripherals. PCWorld praised its stability, performance, display port mix, and front-mounted charging ports. TechAdvisor liked the four-display Windows support, but also flagged the weak USB-A charging, missing card readers, missing audio, and poor Mac fit. That matches the bigger picture. This is a Windows-first dock for people who care more about monitor outputs than Thunderbolt daisy chaining. At the normal $379.99 price, it is hard to recommend over a CalDigit TS4, Kensington SD5700T, or a cheaper Anker model unless you specifically need its HDMI plus dual DisplayPort layout. When the price drops below about $250, it becomes much more interesting. Buy it for a Thunderbolt 4 Windows workstation with multiple monitors. Skip it for base Apple Silicon Macs, older Thunderbolt 3 setups, or any desk where card readers and audio matter.

Frequently Asked Questions

Does the Anker 778 support four monitors?

Yes, Anker advertises support for up to four 4K displays on compatible hosts. In practice, the laptop's GPU and Thunderbolt implementation matter. Treat quad display as a Windows Thunderbolt 4 feature, not a guarantee for every laptop.

Can the Anker 778 charge my laptop?

Yes. The upstream Thunderbolt 4 port can deliver up to 100W to the host laptop. The dock ships with a 180W power adapter, which leaves power for the dock and the two 30W front USB-C ports.

Does the Anker 778 work with MacBook?

It is a poor Mac pick. Anker says the 778 is not compatible with M1 or M2 MacBooks. TechAdvisor also warns that even higher-end Apple Silicon MacBooks may only run external displays in mirrored mode with this dock.

What ports does the Anker 778 have?

The 778 has one upstream Thunderbolt 4 host port, one downstream Thunderbolt 4 port, two USB-C 10 Gbps ports with 30W charging, two USB-A 5 Gbps ports, two USB-A 2.0 ports, Gigabit Ethernet, HDMI 2.1, and two DisplayPort 1.4 outputs.

Is the Anker 778 worth it?

It can be worth it for a Windows Thunderbolt 4 laptop with several external monitors, especially on sale. At the normal $379.99 price, many buyers will get better value from a cheaper Thunderbolt 4 dock or a Mac-friendly premium dock.
