High Power Gigabit PoE++ Injector Adapter - 90W Gigabit PoE Injector

In this review the High Power Gigabit PoE++ Injector Adapter is evaluated for small installations that need to convert a non-PoE port into a high-wattage PoE source. The bottom line: this injector is aimed at installers and small-business IT staff who need up to 90W delivered over a single Gigabit Ethernet link with simple, no-configuration setup. It stands out because it combines an internal AC/DC converter and surge protection in a compact unit so devices receive reliable power without an external brick or complicated setup.

Key Features

• Up to 90W output: Delivers up to 90W to PoE++ devices while remaining backwards compatible with lower-power PoE, keeping a variety of devices powered from one injector.
• IEEE standards compliant: Supports IEEE 802.3af, 802.3at and 802.3bt 4-pair operation so compatibility with existing cameras, phones and access points is straightforward.
• Gigabit network speed: Provides 1 Gigabit Ethernet input and output for full duplex 1Gbps performance so network throughput is not sacrificed for power delivery.
• Internal power supply: Built-in AC/DC converter removes the need for an external power brick, reducing cable clutter and simplifying installation.
• Surge protection: Integrated surge protection helps avoid damage to connected equipment in environments with unstable power spikes.
• Long reach: Supports PoE delivery up to 100 meters (328 ft), covering typical runs for cameras and access points without repeaters.

Who It's For

This adapter is best for small IT teams, integrators and DIY networkers who need a compact way to add PoE++ power to a single non-PoE Gigabit port. It is particularly useful when powering higher-drain devices such as PoE++ cameras or wireless access points that require more than standard PoE or PoE+ can provide.

Those who need multi-port PoE switches, advanced management features or enterprise-grade redundancy should look elsewhere; this injector is a single-port, plug-and-play solution intended for point installations rather than rack-scale deployments.

Pros & Cons

Pros

• Supports up to 90W and is backwards compatible with 802.3af and 802.3at devices, allowing mixed deployments.
• Built-in AC/DC power supply avoids an extra external power brick and simplifies wiring.
• Gigabit pass-through keeps network speeds at 1Gbps while delivering PoE power.
• Customers report solid build quality and cool running operation during normal use.

Cons

• Single-port design limits use to one device at a time, so it is not a replacement for multiport PoE switches.
• Not a managed device, so it lacks remote power monitoring or per-port control features expected in enterprise equipment.

Our Verdict

The High Power Gigabit PoE++ Injector Adapter is a practical, good-value choice for anyone who needs to add a single high-wattage PoE++ feed without reworking infrastructure. It combines 90W PoE output, Gigabit throughput and an internal power supply in a compact, plug-and-play package, making it ideal for point installations of cameras and access points where management features and multiport capacity are not required.

Frequently Asked Questions

Will this power PoE++ cameras that require 60W?
Yes. It supports 802.3bt 4-pair operation and can deliver 60W to devices that use 4-pair PoE standards.

Do I need an external power brick?
No. The adapter has an internal AC/DC converter, so no external power brick is required.

Does it affect network speed?
No. The injector supports 10/100/1000Base-T and provides full duplex 1Gbps pass-through on the Ethernet link.
