Small black RJ45 splitter with three female ports and USB power lead

Vszerda

Vszerda RJ45 1 to 2 Female LAN Ethernet Splitter Adapter network ethernet cable

SKU CH-EEYN-M2F48

An RJ45 splitter with one input and two output ports plus USB 3.3 V power lets two wired devices share a 10/100 Mbps router connection simultaneously

  • Share internet between two devices from one router port using 10/100Mbps splitter
  • Add two wired connections instantly with plug-and-play 1-to-2 RJ45 adapter
  • Power the splitter via USB 3.3V supply for reliable operation
  • Auto-negotiating ports adjust speed and duplex for optimal compatibility
  • Energy-efficient design reduces power consumption based on link status and cable length

RJ45 1-to-2 Splitter for Wired Sharing

This adapter turns one router port into two 10/100 Mbps RJ45 connections so a PC, laptop, smart TV or set-top box can share the same internet link simultaneously. It requires a 3.3 V USB power supply to operate and works with Cat5, Cat5e and Cat6 cabling. No driver or configuration is needed.

Passive Cooling and Low Power Draw

The unit has no fan and relies on its plastic housing to dissipate the minimal heat produced by the embedded 10/100 PHY switch controller. Automatic energy-saving technology adjusts consumption according to link status and cable length, keeping noise at zero and power draw very low during normal use.

USB Power Cable and Auto-Negotiation

A short USB cable is included for connection to any standard wall charger, providing the required 3.3 V supply. Built-in Auto MDI/MDIX and automatic speed negotiation handle crossover detection and optimal link setup without user intervention, while 802.1p and DSCP QoS support preserves traffic priority across both ports.

Questions about this item

How do I install this splitter so both devices share one router port?

Plug the single RJ45 port into your router, connect the two other RJ45 ports to your devices, then attach the USB power cable to a 3.3V wall charger — the splitter will not work without external power.

What maintenance or replacement will this adapter need over time?

No moving parts or firmware to maintain; if a port stops negotiating at 10/100Mbps, replace the whole adapter as the embedded PHY switch controller is not serviceable.

What limit appears first when both connected devices run sustained traffic?

The 100Mb shared bandwidth across the three 10/100Mbps RJ45 ports becomes the bottleneck before the Vcore regulator or QoS features are stressed.
