Lenovo 4X90X21427 dokovacia stanica/port replikátor pre notebook USB 3.2 Gen 2 (3.1 Gen 2) Type-C sivá

Connect USB drives, keyboards, mice and external DVD burners to USB‑C notebooks at the same time with the Lenovo USB‑C to 4×USB‑A Hub (Docking Station Lenovo 4X90X21427). This compact adapter provides four USB‑A ports and a USB‑C host interface (USB 3.2 Gen 2) for high‑speed connectivity. Weighing 42 g and finished in grey, the dock is designed for portability and easy storage in a pocket or carry case. Note: depending on the host’s power capability and peripheral power consumption, the hub supports a total maximum output current of up to 3 A. Actual data transfer speeds may be lower than the theoretical maximums (5 Gbit/s for USB 3.1 Gen 1, 10 Gbit/s for USB 3.1 Gen 2, 20 Gbit/s for USB 3.2) depending on host and device performance, file attributes and system environment.

Advantages

The Lenovo docking station offers four USB‑A ports to expand a USB‑C notebook’s connectivity without requiring additional drivers. Its lightweight 42 g construction and compact grey casing make it convenient to carry and store. The USB 3.2 Gen 2 Type‑C host interface enables high‑speed data transfer when paired with compatible hosts and peripherals, while backward compatibility with USB 3.2 Gen 1 (USB 3.1 Gen 1) devices ensures broad device support.

Suitable for

• Users who need to connect multiple USB‑A peripherals to a USB‑C notebook
• Office work with keyboards, mice and external storage devices
• On‑the‑go professionals who require a lightweight, pocketable hub
• Connecting external DVD burners and other USB peripherals

Key specifications

• Model: Docking Station Lenovo 4X90X21427
• Host interface: USB‑C (USB 3.2 Gen 2)
• Ports: 4 × USB‑A (USB 3.2 Gen 1 / USB 3.1 Gen 1)
• Weight: 0.042 kg
• Colour: Grey
• Maximum total output current: up to 3 A (dependent on host and peripherals)

How to use

Plug the hub’s USB‑C connector into a compatible USB‑C host port on your notebook. Connect USB‑A peripherals — such as drives, keyboard, mouse or external optical drive — to any of the four USB‑A ports. Ensure the host device supplies sufficient power for connected peripherals; if multiple power‑hungry devices are attached, consider using externally powered alternatives or reduce the number of active devices to stay within the hub’s 3 A total output limit. File transfer speeds will depend on host and peripheral capabilities as described above.

Recommendations

For optimal performance, connect high‑speed storage devices directly to the host or use a host and peripherals that support the same USB generation. Avoid attaching many high‑power devices simultaneously to prevent exceeding the hub’s maximum output current.
