Built to complement popular ultrabooks and business laptops—from Dell XPS to Lenovo X1 Carbon and HP Elite/ProBook—this USB-C mini dock is the small, powerful companion your workflow needs for presentations, coding sessions, design work, and media editing on the go. Its blend of performance, portability, and versatility makes it an essential upgrade for anyone seeking a cable-free, clutter-free desk setup or a dependable travel docking station for remote work.

Inside a sleek, travel-friendly chassis, the adapter houses a robust set of ports that are engineered to deliver high-bandwidth performance without sacrificing portability. The dual HDMI outputs support HDR content and uncompressed 4K video at 60Hz, enabling you to drive two external displays from a single USB-C source. If you rely on multiple displays to multitask across spreadsheets, IDEs, and design apps, you’ll appreciate the smooth, simultaneous output that MST (Multi-Stream Transport) enables. The inclusion of a 100W Power Delivery (PD) profile means you can charge your laptop while you work, keeping your device topped up without needing to carry a separate charger for every session. A pair of USB-A 5Gbps ports offers rapid data transfer for external drives and peripherals, while the Gigabit Ethernet port provides a reliable, wired network connection for stable video conferencing, large file transfers, and low-latency online collaboration. The SD and MicroSD card readers complete the package, making it easy to offload footage or transfer media cards directly to your PC or Mac without removing anything from your workflow. All this capability is packed into a compact dock that slips easily into a backpack or briefcase, ready to deploy at a moment’s notice.

• Dual HDMI 4K 60Hz support—Experience crisp, high-bandwidth display output with HDR and uncompressed video. This dock leverages DP 1.4 Alt Mode with DSC and MST to drive two external displays from a single USB-C host, enabling expansive multitasking and immersive presentations on both screens.
• 100W USB-C Power Delivery—Charge your laptop while docked. The Power Delivery input supports up to 100W, so you can keep your notebook powered during heavy workloads without swapping adapters or cables. This is ideal for thin-and-light laptops that demand steady, reliable charging while you work remotely.
• 2x USB-A 5Gbps hubs—Fast, easy access to peripherals like external SSDs, keyboards, mice, and USB accessories. The two 5Gbps ports provide ample headroom for data-heavy transfers, accelerating your workflow and reducing bottlenecks when moving large files across devices.
• Gigabit Ethernet (GbE)—A dependable wired network option for high-speed, low-latency connectivity. Perfect for video calls, online collaboration, and environments where Wi-Fi is inconsistent or restricted, ensuring stable performance during important meetings or large file transfers.
• SD/MicroSD card readers—Direct card access for photographers, videographers, and creative professionals. Quickly import media, back up shoots, or transfer project footage to your computer without needing a separate card reader.

How to install StarTech.com USB C Multiport Adapter

To set up your USB C Multiport Adapter, start with a clean, uncluttered workspace and the latest firmware or driver updates on your host device if available. While many systems recognize the dock automatically, following these steps ensures you achieve the best possible performance and stability.

Step 1: Connect the dock to your laptop using the USB-C port. Ensure your laptop supports DisplayPort Alt Mode over USB-C to enable video output to the HDMI displays. If your device requires it, enable DP Alt Mode in BIOS/UEFI or display settings.

Step 2: Connect your external displays to the two HDMI ports on the dock. If you are using two 4K monitors, configure each display to its native resolution of 4K (3840 x 2160) at 60Hz in your operating system’s display settings. Decide whether you want a mirrored or extended desktop to maximize productivity.

Step 3: Attach the Gigabit Ethernet cable to the RJ-45 port for a stable, wired network connection. This is especially useful during video calls, large uploads, or when Wi-Fi performance is unreliable in your environment.

Step 4: Connect USB devices to the USB-A ports. This includes external SSDs, keyboards, mice, or audio devices. The 5Gbps bandwidth supports fast drive access and smooth peripheral performance; if you are using a high-speed SSD, ensure it is connected to one of the USB-A ports for best results.

Step 5: If you want to charge your laptop while docking, plug your PD charger into the USB-C Power Delivery input. This step is recommended for laptops that require a steady supply of power during heavy workloads or long sessions away from a traditional desk charger.

Step 6: Insert SD or MicroSD cards into the appropriate readers when you need to transfer media. Your operating system should recognize the cards immediately, letting you copy or import files directly without additional software.

Step 7: Power on your system (if it isn’t already) and adjust display and audio preferences as needed. You can customize display arrangement, scaling, and sound output to ensure a seamless, distraction-free workflow across both HDMI displays and any connected peripherals.

Frequently asked questions

Q: Can this dock drive two 4K displays at 60Hz simultaneously?
A: Yes. The dock supports dual HDMI outputs with DP 1.4 Alt Mode, DSC and MST, enabling two external displays at up to 4K resolution per screen at 60Hz, provided your host system and displays support these specifications.

Q: Will the adapter charge my laptop while connected?
A: It can. The dock includes a 100W USB-C Power Delivery input, allowing you to charge your laptop while using the dock. For charging to occur while under heavy load, connect a compatible PD charger to the USB-C input. Some laptops may require a higher wattage or have reserved power for internal components; in those cases, performance may vary slightly.

Q: Do I need drivers or software to use this dock?
A: In most cases, you can use the dock plug-and-play on Windows, macOS, and many Linux distributions. Some features (like HDR or MST-based multi-display configurations) may require OS-level adjustments, but no additional drivers are typically necessary for basic operation.

Q: Are the USB-A ports sufficient for high-speed peripherals?
A: yes. The two USB-A ports offer up to 5Gbps bandwidth, suitable for fast external drives, peripherals, and many USB accessories. If you are transferring large video files, using an external SSD on these ports helps maintain quick data movement.

Q: Can I read SD and MicroSD cards through the dock while my laptop is connected to other peripherals?
A: Absolutely. The SD and MicroSD card readers are independent of other ports on the dock, so you can import media or transfer files without disconnecting other connected devices. This is particularly useful for photographers and videographers working on location or traveling.
