PoE Injectors for Single-Device Power Delivery

A PoE injector sits between your switch and a PoE device, adding power to the ethernet connection. Island Electrical Supply stocks PoE injectors from Ubiquiti, HPE, StarTech, and TP-Link supporting 802.3af, 802.3at, and 802.3bt standards.

Best for: Installers adding a single PoE device to a network that uses a non-PoE switch, or supplementing an existing switch with additional PoE power.

When to Use a PoE Injector

PoE injectors are ideal when you need to power one or two devices but your switch does not support PoE. If you are powering three or more devices, a PoE Switch is more cost-effective and reduces cable clutter.

PoE Injector Standards

Match the injector to your device requirements: 802.3af delivers up to 15.4W, 802.3at (PoE+) delivers up to 30W, and 802.3bt (PoE++) delivers 60-100W for high-power devices. Check your device specifications before ordering to ensure compatibility.

Frequently Asked Questions

What is a PoE injector?

A PoE injector is a small device that adds Power over Ethernet to a standard ethernet connection. It has two ports: one connects to your switch (data only) and one connects to your PoE device (data plus power). It plugs into a wall outlet for its power source.

Do I need a PoE injector or a PoE switch?

Use a PoE injector when you have one or two devices to power and your existing switch does not support PoE. Use a PoE switch when you have three or more PoE devices, as it is more cost-effective and keeps cabling cleaner.

Are PoE injectors compatible with all devices?

PoE injectors work with any device that supports the matching IEEE standard (802.3af, 802.3at, or 802.3bt). Check your device's PoE requirements and choose an injector that meets or exceeds the required wattage and standard.
