Gigabit PoE+ Injector, 30W 48V, Black | 10/100/1000Mbps, IEEE 802.3af/at Compliance, Extend Network Up To 100M (328 ft), Plug and Play

This unit powers my U7 Pro Access point without any issues and was a great price

This PoE injector worked great as soon as I plugged it in and attached the Ethernet cables. They could have included provisions for hanging/attaching it to a wall of side of a desk or cabinet. Mine has to be on the floor near the baseboard below the electrical outlet it’s plugged in to. Minor quibble. Can’t talk about reliability since I’ve only had it for a couple of weeks now. Only time will tell. I hope it turns out to be as reliable as the Ethernet switches I’ve had for more than a decade with absolutely no problems.

Needed this to power a Ruckus access point. Not only did it work perfectly, but I was also surprised to see that it established a 5Gbit link just fine despite that being beyond specification of this unit.

I had never done this before - trying to power a mini stick PC over Ethernet - but I read the power specs and this fit the bill. It works! That’s all I can ask for. Recommended.

worked well for application

I could not get it to work behind a D-Link switch (unmanaged, non-Poe). But I was able to get it to work from a port leaving the router directly. So, I can say it works fine in the right situation. I used it for a Poe security camera, and I verified the specifications extensively to ensure a match before purchasing. I hunted for days to find a solution to connect it to the switch before making extensive rearrangements to use it and not return it.

Works great

Works as it should. It does gets a little warm. Connection works fine, plug and play.
