This article covers Anker 778 Thunderbolt ドッキングステーション (12-in-1.

Overview

The Anker 778 Thunderbolt Docking Station is a high-end 12-in-1 dock built around Thunderbolt 4 connectivity. With a single Thunderbolt 4 cable to your laptop, you gain access to up to 8K external displays, wired Gigabit Ethernet, multiple USB ports, and 100W Power Delivery charging — all at once. It's designed for professionals who need a clean, single-cable desktop setup without sacrificing performance. What sets this dock apart is its ability to drive up to four displays simultaneously. A single display can run at 8K (30Hz), while two or three displays max out at 4K each. Even with four displays connected, you still get 4K resolution per screen. This makes it an ideal choice for creative workflows, financial trading, or any multi-monitor productivity environment.

Connectivity & Compatibility

The Anker 778 packs a comprehensive port selection: Thunderbolt 4 upstream port (100W PD input, for host PC) ×1 Thunderbolt 4 downstream port (40Gbps data, 8K output) ×1 HDMI port (8K@30Hz) ×1 DisplayPort ×1 USB-C ports (USB PD 30W output) ×2 USB-A ports (USB 3.2 Gen2 10Gbps) ×3 USB-A port (USB 2.0) ×1 3.5mm audio combo jack ×1 * Gigabit Ethernet (RJ45) ×1 Compatible with Windows 10/11, macOS, and Chrome OS. Full Thunderbolt 4 bandwidth requires a Thunderbolt 4 or USB4 host. Note that macOS does not support extended desktop mode across multiple displays — only mirroring is available.

Product Info

Released in November 2022, the Anker 778 Thunderbolt Docking Station sits firmly in the high-end segment. Despite its premium feature set — 12 ports, 8K support, 100W PD, and quad-display output — it's priced competitively among Thunderbolt 4 docks. Anker backs it with an 18-month warranty. The package includes the dock, a 180W AC adapter, power cable, a 0.7m Thunderbolt 4 cable, and a quick-start guide. It's widely available through and Anker's official store.

Best Use Cases

Creative Professionals: Video editors, 3D artists, and photographers who need multiple high-resolution monitors for timelines, previews, and tool palettes. The 8K single-display support is a bonus for future-proofing. Remote Workers & Home Office Users: Transform a single laptop into a full desktop workstation with dual or triple monitors, wired Ethernet, and peripheral connections — all through one cable. Financial Traders & Data Analysts: Four displays let you monitor charts, spreadsheets, news feeds, and communication tools simultaneously, boosting situational awareness. This dock may be overkill for: Users who only need one or two external displays and don't require Thunderbolt speeds — a basic USB-C hub would suffice at a lower cost. * macOS users who need extended desktop across multiple monitors (mirror-only limitation).

Things to Consider

Before buying, verify that your laptop supports Thunderbolt 4 or USB4. Older Thunderbolt 3 laptops will work but may have reduced bandwidth for multi-display setups. macOS users should be aware of the extended display limitation — this is an Apple-imposed restriction, not a dock flaw. When running four 4K displays, pay attention to bandwidth allocation. Some port combinations may cap refresh rates depending on total resolution. For 100W PD charging, use only the Thunderbolt 4 upstream port; simultaneous USB-C PD usage drops charging to 65W. ## FAQ
Q: Can I use this dock with a non-Thunderbolt USB-C laptop? A: Physically yes, but you'll lose Thunderbolt 4 features. Data speeds drop to USB 3.2 Gen2 levels, and multi-display/8K output won't work. It'll function as a basic USB-C hub. Q: Is it compatible with gaming laptops? A: Yes, as long as the laptop has a Thunderbolt 4 port. Note that this dock does not support external GPU (eGPU) enclosures — the Thunderbolt ports are for data and video only. Q: Can I replace the included Thunderbolt 4 cable with a longer one? A: Yes, you can use any certified Thunderbolt 4 cable up to about 2 meters. Longer cables may introduce signal degradation, so choose a high-quality option.
