POE Extender RJ45 4-Port 10/100M IEEE802.3at to 802.3af - PoE Powered

In this review the POE Extender RJ45 4-Port by exgoofit is assessed for installers who need a compact, powered way to extend Ethernet and PoE beyond standard cable limits. The bottom line: this device is best for site installs like hotels, schools, or surveillance projects where a single PoE input must be relayed to multiple devices without nearby power outlets. Its main selling point is a simple, plug-and-play way to forward both data and PoE power up to an additional 120m over Cat5 UTP, making it a practical relay when running separate power is impractical.

Key Features

• PoE pass-through: Forwards both Ethernet and PoE power so remote APs, cameras, or IP phones can be powered through the same Cat5 cable without extra adapters.
• Standards compliant: Accepts IEEE 802.3at as power-in and provides IEEE 802.3af power-out, helping compatibility with a wide range of PoE devices.
• Four output ports: Offers four powered RJ45 outputs from one PoE input, useful for distributing network and power to multiple endpoints from a single feed.
• Distance extension: Can extend PoE and Ethernet an additional 100 to 120m over Cat5 UTP with good cable, making it suitable for long runs where switches or outlets are unavailable.
• Plug-and-play: No configuration required, so it can be installed quickly in the field to relay signal and power without network setup.
• Power management: Total available output is capped at 25.5W so installers must budget power across the four ports to avoid overloads.

Who It's For

This unit is aimed at network installers and site technicians who need to extend PoE feeds to several nearby devices without access to local AC power. It suits deployments such as wireless access points, IP cameras, or IP telephony in buildings where a single PoE feed can be split to serve multiple endpoints.

It is not ideal for projects that require full 15.4W on all four outputs simultaneously or for long cascades of extenders; planners should verify device power draw and avoid excessive series cascading to prevent voltage drop and unreliable operation.

Pros & Cons

Pros

• Simple plug-and-play design that forwards both data and PoE without configuration.
• Supports up to 120m additional transmission with quality Cat5 UTP cable, extending deployment options.
• Compliant with IEEE 802.3at input and 802.3af outputs for broad device compatibility.
• Four output ports allow one feed to serve multiple devices, reducing cabling and power needs.

Cons

• Total output power is limited to 25.5W, so not all four ports can deliver the full 15.4W simultaneously.
• Performance depends on cable quality and run length; poor cable can reduce range below optimal figures.

Our Verdict

The exgoofit POE Extender RJ45 4-Port is a reliable, low-configuration solution for extending PoE and Ethernet to multiple nearby devices when AC power is absent. Installers who budget power per port and use quality Cat5 cabling get a practical relay that reduces wiring complexity and extends reach, making it good value for site projects like camera and access point deployments.

Frequently Asked Questions

Can this extender power four devices at full 15.4W each?
Answer. No, the total output is 25.5W so you must budget power across ports; not all four can deliver 15.4W simultaneously.

How far can this unit extend PoE over Cat5?
Answer. With high-quality Cat5 UTP it can forward data and PoE an additional 100 to 120m, but poor cable may reduce that range.

Is any configuration required to use it?
Answer. No configuration is needed; it is plug-and-play, but installers should follow the manual for power and wiring guidelines.
