Network switch Renkforce RF-GES-400 4-port with USB power

The Renkforce RF-GES-400 4-port network switch is a compact device that expands wired Ethernet connectivity in small offices, home networks and multimedia setups. It offers four RJ45 LAN ports that support automatic link detection and standard Ethernet speeds, allowing multiple devices such as computers, printers and NAS units to be connected to a single network segment. The unit is designed for flexible placement and can be powered via a USB connection, eliminating the need for a dedicated mains adapter in constrained environments.

Advantages

This network switch provides four additional wired Ethernet ports in a small form factor, enabling straightforward expansion of an existing network without configuration. USB power support allows installation near devices or behind furniture where mains sockets are not available. The plug-and-play design and auto-negotiation on each port minimise setup effort and make the switch suitable for users who need reliable wired connectivity with minimal technical steps.

Suitable for

• Extending wired connections in home networks
• Small office setups requiring extra LAN ports
• Connecting printers, NAS devices and media players
• Temporary network expansions for events or workshops

Key specifications

• Number of ports: 4 RJ45 Ethernet ports
• Data rates: compatible with standard Ethernet speeds (auto-negotiation)
• Power method: USB power input for DC supply
• Form factor: compact, desk- or shelf-mountable housing
• Network features: plug-and-play operation, automatic link/activity LEDs per port

How to use

Connect the switch to your existing router or network by using a standard Ethernet cable from one of the switch ports to a LAN port on the router. Plug devices into the remaining ports with Ethernet cables. Provide power by connecting a compatible USB power source to the switch’s USB power input — a USB wall adapter, power bank or a USB port on an existing device may be used if it supplies the required voltage and current. The switch will automatically detect link speeds and establish network connections without additional configuration.

Usage recommendations

Place the switch in a ventilated area, avoid stacking heavy objects on top, and use shielded or high-quality Ethernet cables for best performance. When using USB power, verify the power source can deliver stable output to ensure reliable operation under load. For critical or high-traffic environments, consider a powered switch with dedicated adapter or managed alternatives that offer traffic control and monitoring.
