USB-C Gigabit Network Adapter SBOX H-994, 1000 Mbps Ethernet, USB-C to RJ45

SBOX H-994 is a USB-C Gigabit network adapter that provides a wired Ethernet connection up to 1000 Mbps through a devices USB-C port. The adapter converts a USB-C interface to an RJ45 network port, enabling stable wired internet access for laptops, tablets and desktop computers that lack a built-in Ethernet jack. It supports standard Ethernet networking for tasks that require consistent bandwidth, low latency and reliable connectivity.

Advantages

The adapter offers plug-and-play connectivity with minimal setup on most modern operating systems, delivering a full Gigabit link for high-speed transfers. Its compact form factor and single-cable design make it easy to carry and connect without external power. The SBOX H-994 reduces packet loss and latency compared to wireless connections, improving performance for video calls, large file transfers and online collaboration.

Suitable for

• Connecting laptops and tablets without Ethernet ports to wired networks
• Stable internet access for video conferencing and VOIP
• Fast file transfers between networked devices
• Office workstations requiring reliable wired connectivity
• Home networks where Wi-Fi is unstable or congested

Key specifications

• Interface: USB-C to RJ45 Ethernet
• Maximum data rate: up to 1000 Mbps (Gigabit Ethernet)
• Supported network modes: 10/100/1000 Mbps auto-negotiation
• Connector type: USB-C plug and standard RJ45 port
• Power: bus-powered via USB-C (no external power adapter)
• Form factor: compact, portable adapter

How to use

Connect the USB-C plug of the adapter to the host devices USB-C port and attach an Ethernet cable from the RJ45 port to a network switch, router or wall outlet. Most modern operating systems will detect the adapter automatically and install required drivers or use built-in drivers. Verify the network link and configure network settings (DHCP or static IP) in the system network preferences if necessary. Once connected, the adapter provides a wired network interface for immediate use.

Recommendations

For best performance, use a Cat5e or better Ethernet cable and connect to Gigabit-capable network equipment. Avoid excessive bending of the USB-C connector and disconnect by pulling the adapter body rather than the cable to prolong service life. If the host device has multiple USB-C ports, connect to a port that supports USB 3.0/3.1 or higher for optimal throughput.
