USB-C adapter SILVERSTONE SST-EP14C — USB 3.1 Type-C to HDMI + 3× USB 3.1 Type-A

SILVERSTONE SST-EP14C is a compact USB-C adapter that converts a USB 3.1 Type-C port into an HDMI output and three USB 3.1 Type-A ports. It provides a straightforward way to add an external display via HDMI while simultaneously expanding a laptop or tablet's available USB-A connections for peripherals, external storage and accessories. The adapter is designed for portability and simple plug-and-play operation without additional drivers on most modern systems.

Advantages

The adapter supports video output through HDMI while preserving high-speed data transfers on the three USB 3.1 Type-A ports. Its compact housing and single-cable connection reduce clutter and make it suitable for mobile use. Because it uses the USB-C interface, the device offers broad compatibility with laptops and tablets that support USB 3.1 or DisplayPort Alternate Mode over Type-C. No external power supply is required for typical peripheral use.

Suitable for

• Extending laptop or tablet display to an external monitor or projector via HDMI
• Connecting USB-A peripherals such as keyboards, mice and webcams
• Using external storage devices or flash drives at USB 3.1 speeds
• Presentations and video playback in meeting rooms or classrooms
• Travel and remote work where compact connectivity expansion is needed

Key specifications

• Interface: USB 3.1 Type-C input to HDMI output and three USB 3.1 Type-A ports

How to use

Connect the SILVERSTONE SST-EP14C to a compatible USB-C port on your laptop or tablet. Attach an HDMI cable from the adapter's HDMI output to your external monitor or projector. Plug USB-A devices such as a mouse, keyboard or external drive into the three USB 3.1 Type-A ports. The host system should recognize the connected display and peripherals automatically; open display settings on your computer to configure resolution, scaling or multiple-display mode as needed.

Usage recommendations

Ensure your computer's USB-C port supports data transfer and video output (DisplayPort Alternate Mode) for HDMI functionality. For best video and data performance use high-quality HDMI and USB cables and connect devices directly to the adapter rather than through additional hubs. If a peripheral requires higher power than the adapter can supply, use a powered USB hub or connect that device directly to the host.
