USB-C multiport adapter Kruger & Matz KM0400 with HDMI, USB 3.0 and USB 2.0 ports

Kruger & Matz KM0400 is a USB-C multiport adapter that expands a USB-C port with an HDMI video output and two USB Type-A ports (USB 3.0 and USB 2.0). The adapter enables connecting an external monitor, projector or TV via HDMI while simultaneously attaching peripherals such as flash drives, mice or keyboards. The compact design and single-cable connection make it suitable for laptops, tablets and other USB-C devices that support display output and USB data transfer.

Advantages

The adapter combines HDMI and USB-A connectivity in one compact accessory, allowing video output and peripheral connection without additional hubs. The presence of a USB 3.0 port provides faster data transfer rates for external storage, while the USB 2.0 port supports legacy devices like keyboards and mice. Its plug-and-play operation requires no drivers on most modern operating systems, and the small footprint simplifies transport and storage.

Suitable for

• Connecting a laptop or tablet to an external monitor, projector or TV for presentations or extended desktop
• Attaching USB peripherals such as flash drives, external HDD/SSD, mice and keyboards
• Quick data transfer from USB storage devices to a USB-C device
• Using in compact workstations or while travelling when additional ports are needed

Key specifications

• Connector: USB-C (host) to HDMI and two USB-A ports
• Video output: HDMI (supports typical resolutions up to Full HD and common refresh rates depending on host device capabilities)
• USB ports: one USB 3.0 port for high-speed data transfer and one USB 2.0 port for lower-speed peripherals
• Power and data: uses host device power via USB-C; does not include independent power supply
• Form factor: compact, lightweight adapter suitable for portable use

How to use

Plug the USB-C connector into a compatible USB-C port on your laptop, tablet or other device. Connect an HDMI cable between the adapter and the external display to enable video output; configure display settings on the host device if necessary. Insert USB devices such as flash drives, mice or keyboards into the USB-A ports. Most systems will recognise connected devices automatically and allow immediate use.

Usage recommendations

For reliable video output and data transfer, ensure the host device’s USB-C port supports DisplayPort Alternate Mode or HDMI output, and check the display resolution and refresh rate compatibility. Avoid forcing multiple high-power peripherals from the adapter simultaneously; for devices that require significant power, use a dedicated powered hub or connect them directly to the host.
