Gigabit PoE+ Injector, Power Over Ethernet Plus Adapter, 48V | 10/100/1000Mbps, IEEE 802.3af/at Compliant, 15.4W (PoE) or 30W (PoE+), Up to 100 M (328 ft) Range

Great item. Increased my internet speed instantly. I pay for 500Mbps but due to an older POE I was limited to 100Mbps. As soon as I plugged this in, the speed improved immediately. Simple and effective.

I tried a few different brands and this one actually works to run a Cisco 2802E AP that needs true negotiated PoE+/802.3at to function. Its reasonably priced for what it is compared to Cisco branded ones. I wish it had a way to mount the thing but otherwise it seems to work very well. Get this and save the money on Cisco branded Power Injectors

Have purchased a number of these to power PoE security cameras and every one of them has performed well and quite reliably.

works as expected

Bought this to power my Ubiquiti U6-LR Access Point and it works perfectly for that. The injector is next to the switch in my basement and has no issues powering the AP on the second floor of my house (cable run about 30 feet). No appreciable loss of speed so far as I can tell. Only downside is that this cost more than the actual Ubiquiti POE injector, but since those are out of stock this was a sufficient alternative.

It was perfect and a great price

Works as promised right out of the box; a simple solution. Good purchase; I would definitely buy another if needed.

I got this to use with a PoE security camera that is hooked up to an NVR. This one particular camera has been giving me a lot of issues where it disconnects and often needs to be power cycles numerous times before it will be detected correctly. Because of its distance from the NVR and the age of both pieces of equipment, I suspected that it might not be receiving enough power. So, I connected this PoE injector between the NVR and the camera and it powered on and connected correctly in the first try. I think this is a sign that it has done exactly what I needed. Time will tell if the camera continues working so well. I picked this one because of the low price but it does have the disadvantage of only supplying a single PoE port. I think for many applications it would be advantageous to get a PoE injector that supports multiple ports.

Works as intended with a Netgear access point.

The POE injector did not work on arrival, it was flashing green and orange instead of a solid orange as supposed to. I had to return it.
