USB-C Adapter Tech-Protect HB08 HUB 4in1 with USB-A 2.0 and 2x HDMI 4K 60Hz — Space Grey

Tech-Protect HB08 HUB 4in1 is a compact USB-C adapter designed to expand connectivity for laptops, tablets and smartphones with USB-C ports that support video output and data transfer. The adapter provides two HDMI outputs capable of up to 4K at 60Hz and one USB-A 2.0 port for legacy peripherals. Housed in a space grey finish, the HB08 combines display extension and basic USB connectivity in a single plug-and-play accessory suitable for productivity and multimedia workflows.

Advantages

The HB08 enables simultaneous connection of two external displays at high resolution while retaining a USB-A 2.0 port for keyboard, mouse or flash drive use. Its support for HDMI 4K at 60Hz ensures smooth video playback and crisp image quality on compatible monitors or TVs. The compact, single-cable design requires no external power and offers immediate compatibility with USB-C devices that support alternate mode video output and USB data transfer.

Suitable for

• Extending laptop or tablet screens to one or two external displays for presentations and multitasking
• Connecting a computer to a TV or monitor for high-resolution video playback
• Using legacy USB-A peripherals such as keyboards, mice or flash drives alongside external displays
• Mobile work setups that require a small, portable hub for occasional docking

Key specifications

• Ports: USB-C input (host) to two HDMI outputs and one USB-A 2.0 port
• Video output: HDMI up to 4K (3840×2160) at 60Hz per supported output (dependent on host device capabilities)
• USB: USB-A 2.0 data transfer compatible with keyboards, mice and storage devices at USB 2.0 speeds
• Design: compact, single-cable adapter in space grey finish
• Power: bus-powered from host USB-C port (no external power adapter required)

How to use

Connect the HB08 USB-C plug into a compatible device’s USB-C port that supports video output and data transfer. Attach HDMI cables from the adapter’s HDMI outputs to external monitors or a TV. Plug a USB-A peripheral into the USB-A 2.0 port if needed. The adapter is plug-and-play for most systems; the host device may require configuration of display settings (mirror/extend, resolution, refresh rate) in the operating system display preferences. Disconnect the adapter by removing the USB-C plug when finished.

Usage recommendations

For optimal performance, use HDMI cables rated for 4K 60Hz and ensure the host device supports dual external displays and HDMI 4K at 60Hz over USB-C alternate mode. When connecting high-resolution displays, check and adjust display settings on the host to match the monitor’s native resolution and refresh rate. Avoid using high-power USB devices that exceed USB-A 2.0 power limits through the hub.
