Networks Universal 48v Wall Plug POE Injector for Most Cisco / Polycom / Aastra Phones

Works as intended. Replaced a TP Link injector that failed after 2 months. Providing clean power to a Raspberry Pi currently. Will test for a month and decide whether to buy more of this.

Using to run POE to a Wyze camera, working well so far.

Nice, inexpensive, and compact solution for providing power to power-over-ethernet (PoE) devices when your ethernet doesn't actually have power! I'm using it for a Polycom IP 5000 conference phone and it works perfectly.One short ethernet cable goes from the network connection into this device and this device plugs into a power outlet nearby. Then a longer ethernet cable, now carrying power along with the network data, goes from this device to the conference phone.The device feels well-made, the A/C prongs are sturdy and the ethernet ports accept connections securely and with a satisfying "click." This seems like a much better solution than the expensive, branded adapters.

Works perfectly with my 48v 802.3af wifi access point. Great injector for the price.

Proveded sufficient voltage for my VoIP phone, but it produced a hum throug the headset to the other on the other end of the line. Had to send it back, but if you're not using a VoIP phone, or a different brand other than a Yealink, maybe it will work better for you.

This works perfectly with HIK and Laview POE cameras.

The plug in pulsed and would not provide power to the wifi bridge i bought it for.

Not sure what else to add. Works fine.
