Anker 778 Thunderbolt Docking Station Review
Streamline your desk chaos with Anker 778 Thunderbolt Docking Station. This 12-in-1 tech marvel simplifies connectivity, making tangled cables a thing of the past.
The Anker 778 connects your laptop to up to four 4K displays, charges it at 100W, and gives you 12 ports through a single Thunderbolt 4 cable. One cable from the dock to the laptop. Everything else connects to the dock. When you leave your desk, you unplug one cable and walk away. When you come back, you plug in one cable and your entire workstation is live again. That is what a Thunderbolt 4 dock does at its best, and the Anker 778 does it with 40 Gbps bandwidth, which is the fastest mainstream connection standard available.
Anker is one of the most recognized names in charging and connectivity accessories. The 778 sits at the top of their docking station lineup. It ships with a 180W power adapter and a 2.3-foot Thunderbolt 4 cable, so the box contains everything needed to set up immediately. 18-month warranty. Compatible with Dell XPS, ThinkPad, and other Thunderbolt 4 laptops. Not compatible with M1/M2 MacBooks or Asus laptops with AMD CPUs.

Anker 778 Thunderbolt Docking Station (12-in-1, Thunderbolt 4), 40 Gbps with Max 100W Charging for Laptop, Single 8K, Quad 4K Display, Ethernet, 6 USB Ports for Dell, HP Laptops and More(Gray)
12 Ports and What They Actually Do for Your Desk
Numbers on a spec sheet do not convey what 12 ports mean when they are all connected. Here is what a typical Anker 778 desk setup looks like in practice. Your laptop connects to the dock with the Thunderbolt 4 cable. That single connection carries video, data, and 100W of charging power. From the dock, you run cables to your monitors (up to four 4K displays using the HDMI 2.1, two DisplayPorts, and the Thunderbolt downstream port). Your keyboard and mouse plug into the USB-A ports. An external SSD connects to one of the 10 Gbps USB-C ports for fast file transfers. Your phone charges from the other USB-C port at 30W. The Ethernet port gives you a wired network connection that is faster and more stable than WiFi.
The result is a desk where the only cable touching your laptop is the Thunderbolt 4 cable. Everything else connects to the dock. When you need to leave, you pull one cable. When you return, you reconnect one cable and everything is exactly where you left it. No reconnecting monitors. No re-pairing peripherals. No waiting for network to re-establish. The dock remembers nothing because it does not need to. It is a passive hub that routes everything through one connection.
40 Gbps: Why the Speed Matters
Thunderbolt 4 runs at 40 Gbps. To put that in context: USB 3.0 runs at 5 Gbps and USB 3.2 Gen 2 runs at 10 Gbps. The Anker 778’s connection is 4 to 8 times faster than those standards. That bandwidth is not just about transferring files quickly, although it does that too. The bandwidth is shared across everything connected to the dock: video to your monitors, data to your drives, network traffic, and charging negotiation.
When you run four 4K monitors at 60Hz, the video signal alone consumes a significant portion of the bandwidth. A lower-bandwidth dock would force you to reduce display count, drop refresh rates, or sacrifice data transfer speed. At 40 Gbps, the Anker 778 handles quad 4K displays and fast data transfer simultaneously without compromise. The 8K@30Hz single-display option exists because the bandwidth supports it, though most users will use the quad 4K configuration.
100W Charging That Replaces Your Laptop Charger
The upstream Thunderbolt 4 port delivers up to 100W to the laptop. Most consumer laptops charge at 45-65W. Workstation-class laptops may draw 96W. At 100W, the Anker 778 covers the full range of consumer and most professional laptops. The 180W power adapter feeds the dock’s own power needs and the 100W laptop charge simultaneously.
This means your laptop charger stays in your bag permanently. At the desk, the dock handles charging. On the road, you use the charger. You never need to unplug the charger from the wall to move between desk and travel because the dock already provides desk charging. The two USB-C ports add 30W each for phones, tablets, earbuds, or any USB-C device. A fully loaded desk with laptop, phone, and tablet all charging through one dock from one wall adapter. For more on how charging works through USB-C connections, see our USB-C portable monitor guide.
Quad 4K or Single 8K
The display configuration is flexible. One HDMI 2.1 port handles up to 8K@30Hz for a single ultra-high-resolution display. Two DisplayPorts and the Thunderbolt 4 downstream port add three more video outputs. In the quad 4K configuration, you connect four separate 4K monitors and the dock distributes the video signal across all four. Each monitor runs at its native 4K resolution.
For professionals who work with large datasets, financial dashboards, video editing timelines, or software development with multiple IDE windows and terminals, four 4K screens provide workspace that a laptop screen and even a triple portable extender cannot match. The trade-off is that this is a desk-bound setup. The monitors, the dock, and the 180W adapter stay on the desk. You gain maximum screen real estate. You lose portability. For information on how dual monitor setups work, see our docking station for dual monitors guide.
Compatibility and the Exclusions That Matter
The Amazon listing confirms compatibility with Dell XPS and ThinkPad. These are Thunderbolt 4 laptops that Anker has tested and verified. Other laptops with Thunderbolt 4 ports should also work, but Anker has not listed them by name.
The exclusions are specific and important. M1 and M2 MacBooks are not compatible. Apple’s base M-series chips restrict external display output in ways that a Thunderbolt 4 dock cannot override. The listing does not mention M1 Pro, M1 Max, M2 Pro, M2 Max, M3, or newer chips. Those variants support multiple external displays natively and may work, but Anker has not confirmed them. Contact Anker before purchasing if you use a Mac with any M-series chip.
Asus laptops with AMD CPUs are also excluded. This is a specific hardware incompatibility, not a general AMD exclusion. Asus uses a particular Thunderbolt implementation on its AMD models that does not play well with this dock. Other AMD laptops from Dell, Lenovo, or HP are not mentioned in the exclusion.
Setup: Genuinely Simple
The Anker 778 is plug and play. Connect the 180W power adapter to the dock. Connect the Thunderbolt 4 cable from the dock to the laptop. Connect your monitors, peripherals, and network to the dock’s ports. There is no software to install, no driver to download, no configuration utility to run. The laptop detects the dock and its connected devices automatically. Windows and macOS both handle Thunderbolt 4 docks natively.
The 2.3-foot Thunderbolt 4 cable is short, which keeps the desk tidy but limits where you position the dock relative to the laptop. If you need more reach, a longer Thunderbolt 4 cable can be purchased separately, though cable quality matters at 40 Gbps. Cheap cables may not sustain the full bandwidth.

Who This Dock Is For
Professionals who want to plug in one cable and have a complete workstation: The Anker 778 turns any desk into a quad-4K, fully charged, Ethernet-connected, USB-loaded workstation through a single Thunderbolt 4 connection. If you work from a dedicated desk with external monitors and want the cleanest possible cable setup with the most capable port expansion available, this dock handles that. Anker’s brand reputation in charging and connectivity adds confidence. The 180W adapter and Thunderbolt 4 cable included in the box mean nothing additional is needed except monitor cables. For a different Anker docking option, see the Anker 577 Docking Station review.
Mac M1/M2 users, Asus AMD users, or users without Thunderbolt 4: The compatibility exclusions are firm. If your laptop does not have Thunderbolt 4, this dock cannot deliver its full capability. For other connectivity solutions, see our docking stations hub page.
Final Verdict
The Anker 778 does what a top-tier Thunderbolt 4 dock should do: it makes your laptop the only thing you carry. Everything else lives on the desk, connected to the dock, waiting for that one cable to bring it all to life. Quad 4K displays, 100W laptop charging, 40 Gbps data transfer, Ethernet, six USB ports across multiple speed tiers, and a 180W adapter that powers the entire system. The setup is genuine plug and play. The Anker name carries weight in this space for a reason.
The exclusions (M1/M2 MacBooks, Asus AMD) and the 18-month warranty are the honest limitations. The 2.3-foot cable is short. Monitor cables are not in the box. But for a Thunderbolt 4 laptop owner who wants to stop reconnecting monitors and peripherals every time they sit down at their desk, the Anker 778 eliminates that friction entirely. One cable. Full workstation. Every time.
Frequently Asked Questions
Will this work with my MacBook Pro M2 Pro?
The Amazon listing excludes M1/M2 base MacBooks but does not mention Pro or Max variants. M2 Pro supports multiple external displays natively through Thunderbolt. It should work, but Anker has not confirmed it. Contact Anker before purchasing to verify your specific model.
Can I really run four 4K monitors at once?
Yes, using the HDMI 2.1 port, two DisplayPorts, and the Thunderbolt 4 downstream port. Your laptop must support quad display output through its Thunderbolt controller. Most Thunderbolt 4 laptops from Dell and Lenovo support this. Check your laptop’s documentation for maximum external display count.
Do I need to buy monitor cables separately?
Yes. The box includes the dock, the 180W power adapter, the Thunderbolt 4 cable to the laptop, and a welcome guide. HDMI and DisplayPort cables to your monitors are not included. This is standard for docking stations.
Is the 2.3-foot cable long enough?
It depends on your desk layout. If the dock sits right next to the laptop, 2.3 feet is plenty. If you want the dock behind a monitor or at the back of a deep desk, it may be too short. Longer Thunderbolt 4 cables are available separately, but use a high-quality cable rated for 40 Gbps to maintain full performance.
Does this replace my laptop charger?
At the desk, yes. The dock delivers up to 100W through the Thunderbolt 4 connection. Most laptops charge at 45-65W. Your laptop charger stays in your bag for travel. At the desk, the dock handles it.

Docking Station Intelligence
The standards are confusing by design. These three panels decode what manufacturers won’t explain clearly. Applicable to every docking station.
The USB-C Confusion Matrix
The USB-C connector is the single greatest source of buyer confusion in docking stations. The physical plug looks identical whether it carries USB 2.0 at 480 Mbps or Thunderbolt 5 at 120 Gbps — a 250x difference in capability hidden behind the same shape. Manufacturers exploit this by labeling everything "USB-C compatible" without specifying which protocol runs through it. Two docks can look identical on the outside and behave completely differently once you plug them in.
The hierarchy matters because it determines everything: how many monitors your dock can drive, how fast files transfer, whether your laptop charges while docked, and whether you need third-party drivers. Here is the real capability ladder, from slowest to fastest:
The practical takeaway: if your laptop has Thunderbolt 4, buy a Thunderbolt dock. If it only has generic USB-C, verify whether it supports DisplayPort Alt Mode before buying anything with multi-monitor claims. Our buying guide walks through verification steps for every major laptop brand.
Power Delivery: What the Watts Mean
Power Delivery (PD) determines whether your docking station can charge your laptop while you work, or whether you need a separate charger cluttering your desk. The math is simple but rarely explained: your laptop draws a specific wattage under load, and the dock must match or exceed it. If the dock delivers less than your laptop needs, the battery slowly drains even while plugged in — defeating the purpose of a docking station entirely.
Most ultrabooks need 45–65W. Standard business laptops need 65–100W. Gaming and workstation laptops can demand 100–140W or more. The dock’s advertised PD wattage is the maximum it can deliver to your laptop — but this drops if you charge other devices (phones, tablets) through the dock simultaneously. Always leave a 15–20W margin above your laptop’s requirement.
Check your laptop’s original charger wattage — that’s your baseline. Our FAQ covers how to find this for every major brand.
Native Display vs DisplayLink: The Hidden Factor
This is the decision most buyers don’t know they’re making. When a docking station outputs video to your monitors, it uses one of two fundamentally different methods: native (the dock passes your laptop’s GPU signal directly to the monitor) or DisplayLink (the dock compresses video over USB and a software driver renders it). The difference is invisible in marketing materials but profoundly affects your daily experience.
Native output through DisplayPort Alt Mode or Thunderbolt uses your laptop’s actual graphics hardware. There is zero added latency, full DRM support for streaming services, no CPU overhead, and no driver to install. DisplayLink, by contrast, adds 5–15ms of latency (noticeable in video calls and cursor movement), blocks DRM content on connected monitors (Netflix, Disney+ show black screens), consumes 3–8% of your CPU constantly, and requires a driver that Apple’s macOS security updates occasionally break.
DisplayLink exists for one reason: Apple Silicon base chips (M1, M2, M3) can only drive one external display natively. If you need two or more monitors on a base MacBook Air or 13” MacBook Pro, DisplayLink is your only option. For everyone else — Windows users, Mac Pro/Max chip users, Intel/AMD laptops — native is always the better choice.
Native (Alt Mode / Thunderbolt)
DisplayLink (USB compression)
The bottom line: if your laptop supports native multi-display output, always choose a native dock. DisplayLink is a workaround, not an upgrade. See our glossary for detailed definitions.
