PoE Injector Adapter 1 Port Gigabit PoE+ Injector - Easy Power

Our review of the D-Link PoE Injector Adapter 1 Port Gigabit PoE+ (DPE-301GI) finds it best suited for network installers and small-business IT staff who need a compact, no-fuss way to add power to remote devices. The bottom line: this injector delivers reliable PoE+ power over a single Gigabit link so cameras, access points and VoIP phones can be installed where outlets are unavailable, without complex configuration or extra hardware.

Key Features

• Quick and easy installation: Plug-and-play setup requires no software or special configuration, letting installers power devices immediately.
• Extra power for PoE+ devices: Supports IEEE 802.3at to deliver up to 32.4W, enabling higher-power cameras and access points to run from a single cable.
• Gigabit speeds: Auto-negotiating 10/100/1000 Ethernet ensures full bandwidth for high-resolution cameras and demanding wireless APs.
• Long cable reach: Provides power and data over distances up to 100 m (328 ft), expanding placement options for ceiling or pole-mounted hardware.
• Standards compliant: Works with IEEE 802.3af and 802.3at devices for broad interoperability with third-party network gear.
• Compact design: Lightweight form factor makes it unobtrusive and easy to tuck into network closets or near switch stacks.

Who It's For

The injector is aimed at IT technicians, small business owners, and security integrators who need a simple way to add power to a single IP camera, wireless access point, or VoIP phone without reworking electrical infrastructure. Its plug-and-play nature speeds deployments where time and access are limited.

Those managing large networks with dozens of PoE devices, or projects requiring centralized power management, should consider midspan switches or managed PoE switches instead, since this single-port injector is best for individual or small-scale deployments.

Pros & Cons

Pros

• Delivers up to PoE+ power to devices up to 100 m away, reducing the need for nearby outlets.
• Gigabit auto-negotiation preserves network bandwidth for high-resolution video or heavy wireless traffic.
• Plug-and-play installation eliminates setup complexity and speeds field deployments.
• Standards compliance ensures compatibility with IEEE 802.3af and 802.3at equipment.

Cons

• Single-port design limits use to one device at a time, so multiple injectors or a PoE switch are needed for larger installations.
