TRENDnet 2.5G PoE++ Injector TPE-219GI - 90W PoE++ Power

In this review of the TRENDnet 2.5G PoE++ Injector TPE-219GI, the bottom line is simple: this is a practical add-on for network installers who need to deliver both power and faster-than-gigabit data to remote devices without replacing existing switches. The injector converts a non-PoE port into a 2.5G PoE++ output and uses auto-sensing to supply the correct wattage for PoE, PoE+, or PoE++ devices, making it an attractive plug-and-play solution for deployments where cable runs approach 100m and a metal housing and integrated power supply are preferred.

Key Features

• 2.5G Data + Power: Provides a 2.5GBASE-T RJ-45 PoE++ port so devices can get both higher data throughput and power over a single Cat5e or better cable.
• Up to 90W PoE++: Supplies PoE (15.4W), PoE+ (30W), or PoE++ (90W) automatically, which covers a wide range of wireless access points, IP cameras, or VoIP devices.
• Auto-Sensing Technology: Detects the class of the attached device and applies the appropriate wattage to avoid manual configuration and reduce deployment errors.
• 100m Reach: Delivers data and power up to 100 meters (328 ft.) over standard Ethernet cabling, maintaining convenience for typical network layouts.
• Durable Metal Enclosure: The wall-mount designed metal housing improves installation flexibility and provides a robust mounting option for office or wiring closet environments.
• Integrated Power Supply and Support: Built-in power and a three-year manufacturer protection package reduce the need for external adapters and provide post-sale reassurance.

Who It's For

The TPE-219GI is aimed at network installers, small IT teams, and SOHO users who need a simple, reliable way to add PoE++ to an existing non-PoE switch while gaining 2.5G speeds for bandwidth-hungry devices like high-performance wireless access points and multi-stream IP cameras. Its plug-and-play setup and wall-mount form factor suit one-off installs and retrofit projects where replacing the switch is not practical.

Users who should look elsewhere include those who require managed switch features, 10G connectivity guarantees, or specialized power delivery beyond the injector's auto-sensing range. Also consider a full PoE switch when multiple powered ports are needed, as a single-port injector is better for targeted additions rather than whole-rack deployments.

Pros & Cons

Pros

• Provides true 2.5G data speeds while delivering up to 90W of PoE++ power for modern devices.
• Easy installation with auto-sensing technology means no configuration is required for correct wattage delivery.
• Sturdy metal housing and wall-mount design offer flexible and durable installation options.
• Backed by a three-year manufacturer protection and accessible English-language tech support for troubleshooting.

Cons

• Some users report mixed results with power delivery reliability, so devices with higher constant draw should be verified in-situ.
• Single-port injector is not ideal for multi-device deployments where a PoE switch would be more efficient.

Our Verdict

The TRENDnet TPE-219GI is a pragmatic choice for anyone who needs to add a high-power PoE++ output and 2.5G throughput to a specific port without replacing networking equipment. Its auto-sensing power, solid metal build, and 100m reach make it particularly good value for targeted upgrades of access points and cameras, though teams with heavy multi-port needs should prefer a PoE switch instead.

Frequently Asked Questions

Can this injector power PoE++ devices up to 90W?
Yes. The injector supports PoE++ up to 90W and will auto-sense to supply PoE or PoE+ where appropriate.

Will I get 2.5G speeds over existing cabling?
Yes. The device provides 2.5GBASE-T performance over Cat5e or better cabling for higher throughput than standard gigabit ports.

How far can I run power and data from the injector?
Data and power can be delivered up to 100 meters (328 ft.) over Cat5e or better, matching standard Ethernet distance limits.
