Gigabit PoE+ Injector Powerline Adapter — 802.3af/at, Up to 30W Output

Product description

Convert non-PoE devices to PoE devices: This injector adds PoE capability to network endpoints without replacing your existing non-PoE switches or switches that lack PoE support. It injects power onto a single Ethernet cable so compatible devices receive data and power together.

Power delivery and compatibility: The unit uses auto-sensing electronics to supply up to 30W to connected devices (PoE+), while remaining backward compatible with 802.3af (PoE) devices that draw up to 15.4W. The injector includes an integrated power supply so no external brick is required.

Hardware and connectors: Equipped with a 1 Gigabit (10/100/1000 Mbps) RJ45 Ethernet input and a Gigabit PoE+ RJ45 output, the adapter is built with a durable plastic housing and metal ports for reliable cable connections. The compact form factor is designed for desktop or shelf placement.

Included items and cabling: Package contents typically include the injector unit, its attached or separate power cord, and a quick-start guide. It delivers both power and data over a single Cat5e/6 cable and supports run lengths up to 100 meters (328 feet) from injector to device.

Important usage notes: This device is intended for PoE-capable equipment (PoE cameras, access points, VoIP phones). It does not support devices that require separate data and power leads or non-standard passive PoE implementations. Status LEDs indicate power and activity — a steady green shows the unit is powered, and different illumination can appear during active output; occasional colored LED states under load are documented by users as normal in some cases. Ensure the powered device does not request more than 30W.

Standards and applications: Fully compliant with IEEE 802.3af and 802.3at standards, it works with a wide range of PoE-enabled devices including IP cameras, VoIP handsets, and wireless access points. Installation is plug-and-play with no configuration required.

Pros

  • Delivers up to 30W PoE+ with auto-sensing
  • Gigabit data throughput on both ports
  • Plug-and-play, integrated power supply

Cons

  • No built-in mounting bracket
  • Power cord can be thick and stiff
  • Not compatible with devices needing separate power runs

VerdictThis Gigabit PoE+ injector is a straightforward, no-configuration solution for adding PoE to non-PoE networks. It offers auto-detection between 802.3af and 802.3at devices, a dedicated Gigabit input and a PoE+ Gigabit output, and an integrated power supply capable of delivering either standard PoE or PoE+ levels. Installation is plug-and-play and performance in field use is generally reliable, tho

Reviews

  1. Paul S. 5/5

    Plug-and-play with steady output

    Easy to install and provides reliable power to data-only Ethernet jacks. The power cord is fairly heavy and stiff, so it can be tricky in tight enclosures.

  2. Anthony 5/5

    Solid choice for powering a camera

    I needed an injector for an Ethernet camera and this one powered it without fuss. Setup was straightforward and the camera came online right away.

  3. JF 5/5

    Dependable for camera deployments

    Bought several of these to power PoE security cameras; each unit has worked reliably.

  4. Big Mo 5/5

    Restored full connection speed

    Solid unit. My service is 500 Mbps but an old injector capped me at 100 Mbps; swapping in this injector restored the higher throughput immediately.

  5. Terence Dowling 5/5

    Performs as advertised

    Does exactly what it's supposed to do.

  6. Chris 5/5

    Delivers negotiated PoE+ for enterprise AP

    After trying other brands this injector successfully powered a Cisco 2802E that requires negotiated 802.3at. It performs like more expensive OEM injectors. Would be nicer with a mounting option.

  7. Jim. Carroll 5/5

    Solved power for remote Wi‑Fi extender

    I used the injector to power an outdoor Wi‑Fi extender via outdoor-rated Ethernet instead of running new electrical lines. It supplied enough power and I later bought another for my main home.

  8. discerning_customer 5/5

    Powered my Netgear access point

    Worked with a Netgear AP with no issues.

  9. Laurent 1/5

    Failed with my PTZ 802.3at camera

    Unit arrived but would not power a PTZ camera — the status LED alternated colors instead of showing the expected steady state. I returned it.

  10. J. Rueffer 4/5

    Compatible with Ubiquiti U6-LR access point

    Used this to power a U6-LR on the second floor with about a 30 ft cable. It keeps the AP running and I haven't noticed speed loss. Serves well as an alternative to the manufacturer's injector.
