One cable from your laptop to the docking station, and everything else happens automatically: two monitors, Ethernet, peripherals, power. That’s the promise of modern USB-C docks. In practice, many devices fall short due to compatibility issues, insufficient power delivery, or missing ports. The CalDigit TS4, Anker 777, and Dell WD22TB4 take three different approaches to the same goal. A comparison for IT professionals looking to standardize their home office setup.

“A docking station isn’t a gadget. It’s infrastructure. Connect two monitors, Ethernet, and peripherals through a single cable, and you have a full workstation ready in under five seconds.”

Key Takeaways

• CalDigit TS4 is the reference standard: 18 ports, 98W Power Delivery, 2.5 Gbps Ethernet, Thunderbolt 4. Price: around €400. The top pick for developers who demand maximum port variety.
• Anker 777 delivers solid fundamentals for under €200: dual 4K support, 85W PD, Gigabit Ethernet. The pragmatic choice for budget-conscious teams.
• Dell WD22TB4 targets enterprise fleets: centralized management via Dell Client Command Suite, 130W PD for Dell laptops, Thunderbolt 4. Starting at €250.
• Thunderbolt 4 provides 40 Gbps bidirectional and guarantees dual 4K at 60 Hz. USB4 is nominally as fast, but has compatibility gaps with display protocols.
• For IT departments equipping 50+ workstations, the Dell WD22TB4 is the path of least resistance. For individual power users, the CalDigit TS4 remains unbeaten.

Thunderbolt 4 vs. USB4: What Actually Matters

Thunderbolt 4 and USB4 share the same bandwidth on paper: 40 Gbps. In practice, there are differences that become relevant when choosing a docking station. Thunderbolt 4 guarantees dual 4K display output at 60 Hz. USB4 allows manufacturers to treat that requirement as optional. That means a USB4 dock may support dual 4K — but isn’t required to. Anyone who wants certainty should stick to a Thunderbolt 4-certified dock.

The second difference involves PCIe tunneling. Thunderbolt 4 guarantees at least 32 Gbps for PCIe data, which matters for external storage solutions and eGPUs. USB4 can be limited to 16 Gbps. For developers attaching a fast NVMe SSD or an external storage array through the dock, this translates into a measurable difference in file transfer speeds and build times.

Thunderbolt 5, already supported by CalDigit with the TS5 Plus, doubles bandwidth to 80 Gbps and enables up to three 4K displays at 144 Hz or two 8K displays at 60 Hz. For most developers, Thunderbolt 5 isn’t necessary as of March 2026 — few laptops currently support the standard. But anyone buying a dock to last the next five years should at least be aware of the option.

CalDigit TS4: 18 Ports, No Compromises

Since its release, the CalDigit TS4 has been the benchmark among Thunderbolt 4 docks. 18 ports packed into an aluminium chassis with a ribbed design for passive cooling. The port lineup: three Thunderbolt 4 connections (40 Gbit/s), three USB-C ports (10 Gbit/s), five USB-A ports (10 Gbit/s), a 2.5 Gbit Ethernet port, an SD card reader, and a combo audio jack. Add to that 98W Power Delivery over the Thunderbolt cable.

98 watts is enough for every MacBook Pro and most business laptops. Only a handful of high-performance machines with power draws above 100 watts will need a separate charger. The 2.5 Gbit Ethernet connection is 2.5 times faster than standard Gigabit — relevant for developers pulling large container images or loading database dumps over the network. The TS4 can be positioned horizontally or vertically, which helps reclaim desk space.

The price of around 400 euros is steep, but it puts things in perspective when spread across an expected lifespan of five to seven years. Broken down to monthly costs, the TS4 works out to roughly 5 to 7 euros per month. For the productivity gains that come with a one-cable setup, that’s money well spent.

Anker 777: The Best Bang for Your Buck

Not every workstation needs 18 ports. The Anker 777 Thunderbolt Docking Station delivers the core features for under 200 euros: dual 4K output at 60 Hz, 85W Power Delivery, Gigabit Ethernet, two USB-A and two USB-C ports, and an SD card reader. That’s more than enough for a standard dual-monitor setup with a wired network connection and the usual peripherals.

85W Power Delivery fully charges most ultrabooks and MacBook Airs. The MacBook Pro 16-inch and performance-oriented Windows laptops demand more and would need a second charging cable attached, which partially undermines the one-cable appeal. Gigabit Ethernet is adequate for most office networks, but anyone who routinely moves large amounts of data across a local network will notice the gap compared to the CalDigit’s 2.5 Gbit connection.

The Anker is the right call for teams equipping many workstations with solid fundamentals without blowing the budget. Across 50 desks, choosing the Anker over the CalDigit saves roughly 10,000 euros. Whether the missing ports and lower Power Delivery justify that difference ultimately depends on what each employee’s specific setup actually requires.

Dell WD22TB4: Enterprise Management Included

Dell’s WD22TB4 is aimed squarely at IT departments that need to manage docks centrally. The device supports Dell’s Client Command Suite, enabling firmware updates, configuration, and monitoring over the network. For IT administrators overseeing dozens or hundreds of docks in the field, that’s a decisive feature neither CalDigit nor Anker can match.

The hardware is solid: Thunderbolt 4, dual 4K at 60 Hz, Gigabit Ethernet, four USB-A ports, one USB-C port, and one HDMI port. 130W Power Delivery for Dell laptops via proprietary charging, 90W over USB-C for non-Dell devices. The port selection is less generous than the CalDigit’s, but it covers the enterprise standard setup. Pricing sits at around 250 euros, placing it squarely between the Anker and the CalDigit.

One drawback in mixed environments: the full 130W charging only works with Dell laptops. Anyone running MacBooks or Lenovo ThinkPads in the same office gets just 90W over standard USB-C. That’s sufficient for most devices, but power-hungry laptops will still need a dedicated charger. For pure Dell fleets, the WD22TB4 is the logical choice. For heterogeneous environments, it isn’t.

Head-to-Head: Three Docks for Three Scenarios

A direct comparison reveals the strengths of each dock. The CalDigit TS4 puts its 18 ports to work in a setup that simultaneously connects two 4K monitors, an external NVMe SSD, an SD card reader, a wired network, a mechanical keyboard, a mouse, and a USB microphone — all over a single Thunderbolt cable to the laptop. For developers who create content, record podcasts, or regularly swap storage media, that port density isn’t a luxury; it’s a working requirement.

The Anker 777 covers the standard setup: two monitors, Ethernet, mouse, keyboard, headset. For a typical home office used by a web developer or cloud engineer who primarily lives in a browser, terminal, and IDE, that’s entirely sufficient. Fewer ports, but all the common use cases are covered. Anyone who doesn’t need an SD card reader or external drives can save roughly half the CalDigit’s price with the Anker — and lose nothing functionally.

The Dell WD22TB4 earns its place in managed environments. Picture an IT department equipping 80 workstations with Dell laptops and identical dock configurations. Firmware updates roll out centrally via the Client Command Suite, monitoring shows which docks are online, and configuration profiles are pushed remotely. No end user has to run an update app or open a support ticket. For that scenario, the Dell dock isn’t just good enough — it’s the only sensible choice.

A Real-World Setup: Developer Home Office

A battle-tested developer configuration with the CalDigit TS4 at its core: a MacBook Pro M5 connected over Thunderbolt 4, driving two LG 27UN850 4K monitors — one via the integrated DisplayPort, the other via a USB-C-to-DisplayPort adapter on the second Thunderbolt port. Ethernet runs into the 2.5 Gbit port, a Keychron Q1 Max and a Logitech MX Master 4 occupy the USB-A ports, a Shure MV7 USB microphone takes another USB-A slot, and a Samsung T7 Shield SSD for backups sits in the front-panel USB-C port.

The result: one cable to the laptop, everything just works. Plug in each morning, unplug each evening. No drivers, no configuration, no delays. The 98W Power Delivery charges the MacBook Pro 14-inch fully and the MacBook Pro 16-inch to around 85 percent of its maximum charge rate — more than adequate for daily use, since the battery rarely dips below 50 percent when the machine stays permanently connected to power.

Total cost of this setup, excluding laptop and monitors: CalDigit TS4 (400 Euro), Keychron Q1 Max (189 Euro), Logitech MX Master 4 (120 Euro), Shure MV7 (250 Euro), Samsung T7 Shield 2TB (180 Euro). Around 1,140 Euro in total for a peripheral setup that should last three to five years and saves roughly one minute of setup and teardown every single day. Over three years, that’s around 12 hours of working time back.

In Practice: What to Watch When Standardizing

IT administrators selecting a single dock for all workstations should check four factors. First: Power Delivery. The laptop with the highest power draw in the organization sets the minimum requirement. A MacBook Pro 16-inch M5 Max pulls up to 140W — no dock in this price range delivers that. A second MagSafe cable at each desk solves the problem without fuss.

Second: display compatibility. Not every laptop supports dual 4K over USB-C. DisplayLink drivers can bridge the gap but consume CPU resources and occasionally introduce rendering artifacts. Thunderbolt 4 is the more reliable solution here, since it tunnels display output natively via Alt Mode.

Third: networking. In offices running NAS systems, local Git servers, or build farms, the gap between Gigabit and 2.5 Gbit Ethernet actually matters. Teams working exclusively in the cloud won’t notice. Teams regularly pulling 10 GB Docker images across the LAN will.

Fourth: firmware management. With a handful of docks, manual updates are no problem. Beyond 20 devices, centralized management becomes relevant. Dell offers the strongest enterprise support here through the Client Command Suite, which pushes firmware updates remotely. CalDigit and Anker rely on desktop apps that end users must run themselves — which in practice means IT support sends instructions and hopes people actually follow through. For security-critical firmware patches, that’s a real risk, and one that’s simply not acceptable in regulated environments with compliance requirements.

Frequently Asked Questions

Do I need Thunderbolt 4 or is USB-C enough?

Thunderbolt 4 guarantees dual 4K at 60 Hz, fast PCIe tunneling, and a minimum bandwidth of 40 Gbit/s. USB-C (without Thunderbolt) can offer these features, but isn’t required to. For a dual-monitor setup with external storage, Thunderbolt 4-certified docks are the way to go. For a simpler single-monitor setup with basic peripherals, a more affordable USB-C dock will usually do the job.

Do Thunderbolt docks work with all laptops?

Thunderbolt 4 docks are backward compatible with USB-C and USB4, meaning they’ll work with any laptop that has a USB-C port. That said, non-Thunderbolt laptops won’t tap into the full bandwidth. A USB-C laptop without Thunderbolt support may only drive one monitor instead of two. Always check your laptop’s specs before buying.

How many watts of Power Delivery do I need?

Most ultrabooks and MacBook Airs charge comfortably at 30 to 65 watts. The MacBook Pro 14-inch needs 70 to 96 watts. The MacBook Pro 16-inch and gaming laptops can draw anywhere from 100 to 140 watts. For a standard workstation setup, 85 to 100 watts is typically sufficient. If you’re running a high-performance laptop, look for a dock with at least 100W Power Delivery — or keep a separate charger on hand.

Is the premium for Thunderbolt 5 worth it?

As of March 2026, not yet — at least not for most users. Thunderbolt 5 delivers 80 Gbit/s and supports 8K displays, but only a handful of laptops currently support the standard. If you’re buying a dock today and plan to use it for five years, the premium can make sense as a future-proofing investment. For current everyday needs, Thunderbolt 4 covers everything you’re likely to throw at it.
