Why You Can Trust Our Recommendations
We selected the docks in this guide based on Dell compatibility, laptop charging, monitor support, Thunderbolt bandwidth, port selection, networking, firmware support, and overall usefulness in a real workstation. We did not simply choose the dock with the highest advertised resolution or the largest number of connectors.
For the XPS 16 in particular, we gave additional weight to charging behavior. Many third-party Thunderbolt docks provide around 90W to 100W, while the XPS 16 may ship with a 130W USB-C power adapter. That difference can matter during rendering, gaming, compiling, or other sustained high-performance workloads.
Why the Dell XPS 14 and XPS 16 Need Different Docking Advice
The XPS 14 and XPS 16 look similar, but they are not identical from a docking perspective.
The XPS 14 9440 has three Thunderbolt 4 USB-C ports with Power Delivery and DisplayPort support. Depending on the hardware configuration, Dell supplies the laptop with either a 60W or 100W power adapter. A good 90W to 100W Thunderbolt dock is therefore suitable for most XPS 14 configurations.
The XPS 16 9640 is more demanding. Dell specifies a 130W USB-C adapter, and models with dedicated NVIDIA graphics can consume considerably more power under load. Most third-party Thunderbolt docks are limited to approximately 90W or 100W of laptop charging.
This does not mean that a 100W dock will not work with the XPS 16. It usually works well for ordinary office tasks, browsing, meetings, programming, and lighter creative work. However, during sustained CPU and GPU workloads, charging may be slower, Windows may display a slow-charger warning, or the battery may discharge gradually even while the dock is connected.
Choose the Dell WD22TB4 if you:
- use an XPS 16 and want the best chance of receiving the full Dell-supported dock power;
- want Dell-specific features such as the dock power button, MAC address pass-through, and Wake-on-LAN support on compatible systems;
- manage Dell laptops in a business or IT environment;
- prefer firmware and support documentation from the laptop manufacturer;
- need a reliable multi-monitor office workstation.
Choose a third-party Thunderbolt dock if you:
- use an XPS 14 and 90W to 100W charging is sufficient;
- need more USB ports, faster Ethernet, or additional card readers;
- want a dock that will also be used with non-Dell laptops or Macs;
- are willing to connect the original Dell charger separately during the most demanding XPS 16 workloads.
Before buying, use our USB-C docking station compatibility checklist and verify the exact ports, charging power, monitor configuration, and included power supply.
Best Thunderbolt Docks for Dell XPS 14/16
1. Dell WD22TB4 – Best Overall
Best for: XPS 14 and XPS 16 owners who want the safest compatibility, strong Dell-specific charging, business features, and dependable multi-monitor support.
The Dell WD22TB4 is our top recommendation because it is designed specifically for Dell systems and delivers the strongest overall compatibility with the XPS family. With its 180W power adapter, the dock can provide up to 130W to compatible Dell laptops. That makes it a much better match for the XPS 16 than most third-party Thunderbolt docks, which generally stop at 90W or 100W.
The dock includes two DisplayPort 1.4 outputs, HDMI 2.0, a USB-C DisplayPort output, downstream Thunderbolt 4 connectivity, Gigabit Ethernet, and several USB ports. Depending on the laptop graphics configuration and the exact monitor connections, it can support multiple external displays without relying on DisplayLink software.
Dell-specific integration is another major advantage. On supported Dell systems, the dock can provide power-button functionality, MAC address pass-through, Wake-on-LAN, and centralized firmware support. These features are especially useful in offices, schools, and managed business environments.
What we like
- Up to 130W Power Delivery to compatible Dell laptops

How to Choose a Thunderbolt Dock for Dell XPS 14/16
1. Start with charging power
Charging is the most important difference between these docks. The XPS 14 can use a 60W or 100W adapter depending on configuration, while the XPS 16 uses a 130W USB-C adapter.
A 90W to 100W dock is generally enough for an XPS 14. It can also power an XPS 16 during ordinary work, but it may not maintain full performance and battery charge during sustained CPU and GPU loads. Read our docking station Power Delivery guide for a more detailed explanation.
2. Verify your exact XPS 16 graphics configuration
Most XPS 16 9640 configurations include three Thunderbolt 4 ports. However, Dell specifies that RTX 4070 configurations have two Thunderbolt 4 ports on the left and one USB-C 3.2 Gen 2 port with DisplayPort and Power Delivery on the right.
Connect a Thunderbolt dock to one of the confirmed Thunderbolt 4 ports. The ordinary USB-C port can still support useful functions, but it does not provide the same Thunderbolt bandwidth or capabilities.
3. Plan your monitor connections before buying
Do not assume that every HDMI, DisplayPort, or Thunderbolt output can run at its maximum resolution simultaneously. Multi-monitor limits depend on the laptop GPU, DisplayPort version, Display Stream Compression, dock architecture, and the exact combination of ports.
For most office users, dual 4K at 60Hz is the most practical target. Triple- and quad-monitor configurations require more careful compatibility checking.
4. Decide whether you need Dell-specific business features
The WD22TB4 can provide Dell-specific features such as MAC address pass-through, Wake-on-LAN, dock power-button integration, and easier firmware management on supported systems. Third-party docks generally provide standard Thunderbolt functionality but not the same level of Dell platform integration.
5. Match Ethernet speed to your network
The WD22TB4 provides Gigabit Ethernet, which is sufficient for most internet connections and office networks. The CalDigit TS4 and Plugable TBT4-UDZ provide 2.5Gb Ethernet.
If your Dell XPS workstation connects to a 10GbE NAS or professional multi-gig network, Gigabit and even 2.5GbE docks can become the bottleneck. Our Best 10Gb Ethernet Docking Stations guide compares the more specialized high-speed networking options.
A 2.5Gb port only improves performance when the router, switches, NAS, and cabling also support speeds above 1Gbps. Do not pay extra for 2.5Gb networking if the rest of your network is limited to Gigabit Ethernet.
6. Consider external SSD and peripheral bandwidth
Thunderbolt provides up to 40Gbps of total link bandwidth, but displays, storage, networking, and USB devices still share resources. Connecting several 4K displays and multiple fast SSDs can reduce the bandwidth available to each device.
For keyboards, mice, webcams, printers, and ordinary office storage, this is rarely a problem. Creative professionals should place their fastest storage on a downstream Thunderbolt port whenever possible.
7. Check the included cable and power adapter
Use the supplied Thunderbolt cable whenever possible. An ordinary USB-C charging cable may fit physically but fail to provide 40Gbps data, full monitor support, or the expected charging power.
Also confirm that the dock includes its original power adapter. Replacing a high-wattage dock power supply can be expensive, and a lower-powered substitute may reduce laptop charging or peripheral stability.
How to Set Up a Thunderbolt Dock With Dell XPS 14/16
- Update the Dell BIOS, Intel chipset components, graphics drivers, and Thunderbolt-related firmware through Dell SupportAssist or Dell’s support website.
- Install the latest firmware package for the docking station.
- Connect the dock to its original power adapter.
- Use the supplied certified Thunderbolt cable to connect the dock to a Thunderbolt 4 port on the XPS.
- Connect the primary monitor first, then add the remaining displays one at a time.
- Connect Ethernet, keyboard, mouse, audio, storage, and other accessories.
- Open Settings > System > Display in Windows to arrange the displays and choose the correct resolution and refresh rate.
- Check whether Windows reports slow charging. If it does, compare the dock’s Power Delivery with the laptop’s original adapter.
- Install future BIOS, graphics, and dock firmware updates when Dell or the dock manufacturer releases them.
If the dock is not detected, shut down the laptop, disconnect the dock from power for approximately 30 seconds, reconnect the power adapter, and then connect the Thunderbolt cable again. Also test another Thunderbolt port and confirm that the cable is certified for Thunderbolt 4.
Common Problems and Limitations
The XPS 16 may show a slow-charger warning
This is common with third-party docks that provide 90W or 100W instead of the XPS 16’s expected 130W. The dock may still work normally, but charging can be slower and the battery may decrease during heavy workloads.
The battery can discharge while connected
During rendering, gaming, GPU acceleration, or sustained processor loads, the XPS 16 may consume more power than a 100W dock can provide. Use the WD22TB4 or connect the original Dell charger separately when maximum performance is required.
Not every monitor output works in every combination
Dock specifications often list the maximum capability of individual ports rather than the maximum capability of every port at the same time. Always check the manufacturer’s resolution table for the exact dual-, triple-, or quad-display configuration.
Firmware and BIOS versions matter
Thunderbolt docks combine power, display, USB, networking, and security functions. Outdated BIOS, graphics drivers, or dock firmware can cause monitor detection problems, unstable Ethernet, sleep and wake failures, or intermittent USB disconnects.
The dock may become warm
Thunderbolt controllers, Power Delivery electronics, Ethernet, and display processing generate heat. A warm metal enclosure is normal, especially with several displays and fast storage connected. Keep the dock ventilated and read our guide to dock overheating issues if it becomes unusually hot or unstable.
