  • Connect four devices from one Ethernet port
  • Achieve 1000 Mbps speeds on Cat 5/5e/6/7/8 cables
  • USB power cable keeps signal transmission stable

  • Compact 100-gram design fits home and office spaces

Expands One Port to Four

This LIEZHUA Ethernet splitter turns a single RJ45 connection into four ports so up to four devices can share the network at the same time. It accepts Cat 5 through Cat 8 cables and draws power from an included USB cable to keep the link stable. The compact housing fits on a desk, in a patch panel or behind entertainment equipment.

Sustained 1000Mbps Throughput

The adapter maintains gigabit-class speeds across all four ports during continuous transfers rather than only in short bursts. USB power prevents voltage drop that can cause negotiation failures when multiple endpoints are active. Cat 5e or higher cabling is required to reach the rated 1000Mbps ceiling.

Replaces Manual Cable Swapping

It removes the need to unplug and reconnect cables when moving between a PC, console, smart TV and streaming box. The jump is worth it whenever a single wall jack serves several wired devices and running new drops is impractical. It does not suit installations that need managed switching, VLANs or PoE pass-through.

Questions about this item

Does the splitter draw enough power from its USB cable to run four devices all day without overheating?

The USB power cable supplies the splitter so it can keep four connections active continuously; the unit weighs 100 grams and has no fan, so it stays cool in normal indoor use.

What must I already have to make the 1-to-4 splitter work?

You need one incoming Ethernet cable (Cat 5 through Cat 8) and a free USB port or charger for the supplied power cable; the splitter then provides four RJ45 ports for your devices.

Will my older Cat 5e patch cords still reach 1000 Mbps through this adapter?

Yes, the splitter supports up to 1000 Mbps on Cat 5e, Cat 6, Cat 7 and Cat 8 cables, so existing Cat 5e runs will operate at their rated gigabit speed.
