TP-Link POE150S 802.3af Gigabit PoE Injector Adapter

Overview

The POE150S is a compact midspan PoE injector that converts a non-PoE network port into a powered port. It combines data and power into a single Ethernet cable, eliminating the need for separate power runs to remote devices. This is the standard solution when upgrading legacy network infrastructure to support IP cameras, wireless access points, or other powered edge devices without rewiring.

Compatibility

The POE150S conforms to IEEE 802.3af, making it compatible with any device rated for 15.4W maximum power draw — typically entry-level IP cameras, basic wireless access points, and VoIP phones. It is not suitable for high-power cameras (PoE+ / 802.3at devices) or power-hungry outdoor turrets. Verify your target device's power consumption (printed on the device label) before ordering. The injector works with any standard network switch or router that supplies standard Gigabit Ethernet.

Installation Notes

Connect the non-PoE port to your switch or router and the PoE port to your end device. Data and power travel the same UTP cable up to 100 meters (328 feet) — sufficient for most warehouse and office deployments. The plastic housing is pocket-sized, suited to DIN rail mounting or placement under desks. Auto-detection logic prevents power injection to devices already receiving power, reducing risk of double-powering. No configuration required — it operates as a transparent layer-2 pass-through.

When to Choose a Different Model

If your target device requires more than 15.4W (PoE+ / 802.3at standard at 30W, or PoE++ at 60–95W), select a higher-budget midspan or upgrade to a managed PoE switch with sufficient aggregate power budget. For installations exceeding 100 meters, use fiber with a media converter or choose a managed switch with extended-range PoE capabilities.
