Modern laptops have too few ports. A USB-C hub or Thunderbolt dock fixes this — but the wrong one causes display flicker, slow charging, and compatibility headaches. This guide cuts through the confusion.

The Port Problem
Modern thin laptops — MacBooks, Dell XPS, HP Spectre — have as few as two USB-C ports. Connecting a monitor, keyboard, mouse, ethernet, and external drive requires either a hub or significant cable juggling.
The solution — a USB-C hub or docking station — seems simple. In practice, the market is full of products that cause display flicker, deliver insufficient charging power, overheat under load, or simply do not work with specific laptop/monitor combinations.
This guide explains what to look for, which to avoid, and the best options at each price point.
Hub vs. Docking Station
USB-C Hub: A small, portable device that expands one USB-C port into several. Powered by the laptop. Good for adding a few ports on the go. Limited bandwidth means it cannot always drive a high-resolution monitor while simultaneously handling data and charging.
Docking Station: A larger device that connects to mains power. Provides significantly more bandwidth, more ports, and reliable power delivery. Designed for permanent desk use. Can drive dual 4K monitors, charge the laptop at full speed, and handle all peripherals simultaneously.
For a home office where the laptop is used at a fixed desk most of the time, a docking station is the correct choice. For occasional use or travel, a hub is adequate.
Thunderbolt 4 vs. USB-C
Thunderbolt 4 provides 40 Gbps bandwidth — enough for dual 4K monitors, fast external storage, and power delivery simultaneously. USB-C provides 10–20 Gbps depending on version — sufficient for most setups but a bottleneck for demanding configurations.
Check your laptop's port specification before buying. A Thunderbolt 4 dock connected to a USB-C-only laptop operates at USB-C speeds. A USB-C hub connected to a Thunderbolt 4 laptop also only uses USB-C speeds.
What Ports You Actually Need
For most home office setups:
- 1× USB-C/Thunderbolt (to laptop)
- 2× USB-A (keyboard, mouse or drives)
- 1× HDMI or DisplayPort (monitor)
- 1× Ethernet (wired internet)
- 1× USB-C with Power Delivery (laptop charging)
- 1× SD card (optional, useful for photographers)
- 3.5mm audio (optional)
Anything beyond this is useful for specific workflows but not essential for general office use.
Best USB-C Hubs and Docks in 2026
Best Budget Hub: Anker 655 8-in-1 (~£45)
Eight ports including HDMI 2.1, USB-A, USB-C, ethernet, and SD card. Compact, reliable, and works correctly with most laptops. The right choice for occasional use or a second location.
Best Mid-Range Dock: Anker 777 Thunderbolt 4 (~£150)
Thunderbolt 4, dual 4K display support, 90W laptop charging, and a robust aluminium chassis. Works reliably with MacBook and Windows laptops. The best value Thunderbolt dock available.
Best Premium Dock: CalDigit TS4 (~£300)
18 ports, Thunderbolt 4, 98W charging, dual 6K display support, and build quality that matches the premium it commands. The definitive docking station for power users. Every port works as specified, at full speed, under full load.
Best for MacBook: OWC Thunderbolt 4 Dock (~£200)
Designed specifically for Apple Silicon MacBooks. Full Thunderbolt 4, five USB ports, SD card, ethernet, and audio. Reliable compatibility and excellent build quality.
Common Problems to Avoid
Insufficient power delivery: If the dock provides less than 65W charging, your laptop may charge slowly or discharge under load.
Single-cable display limitations: Some USB-C hubs cannot drive a monitor at full resolution while simultaneously handling power and data. Check specifications for single-cable use cases.
Overheating: Budget hubs with plastic enclosures overheat under sustained load, causing throttling. Aluminium enclosures dissipate heat significantly better.
