Power-over-Ethernet injector for remote devices

This GCROWN injector delivers up to 30 W of power and Gigabit data through a single cable run of up to 325 feet. It targets installers who need to supply PoE+ equipment such as wireless access points or IP cameras where no local mains socket exists. The unit requires only a standard grounded AC cord to operate.

Single-cable Gigabit link with built-in supply

One PoE port and one uplink port each run at 10/100/1000 Mbps, so the injector sits inline between a network switch and the powered device. The integrated power supply removes the need for a separate adapter brick, and the housing can be surface-mounted, wall-mounted or slotted side-by-side with additional injectors.

1.5 kV surge protection under continuous load

The 1.5 kV lightning protection helps the injector withstand transient spikes during prolonged outdoor or industrial operation. Rated for a steady 30 W output, it maintains power delivery without thermal throttling during extended use. The all-in-one design keeps the power path short and reliable.

Questions about this item

How much power can the PoE port deliver before it stops?

The port supplies up to 30W of power over Ethernet, which is the maximum output the injector can sustain.

Does the unit get loud or hot when it powers a device all day?

There is no fan, so it runs silently; the metal case dissipates the heat from the built-in supply during continuous operation.

What cable do I need to plug the injector into the wall?

A standard grounded AC cord is included, so the injector connects directly to a mains socket without an extra power brick.
