YuanLey Gigabit PoE++ Injector 90W, Converts Non-PoE to IEEE 802.3bt/at/af, 10/100/1000Mbps Ultra Adapter, Up to 325 Feet, Metal Case Desktop/Wall-Mount, Plug & Play

I used this PoE injector to power an Aruba 345 Access Point. I have been running this setup for some time now, and have had no issues. It fit perfectly into my network cabinet. Seems well made, and the price is great. No complaints here, I would definitely recommend this PoE Injector.

I picked up a Yeacomm 5G outdoor modem, and since it's powered by POE, I wanted a good solution. While I do have a POE switch, I was using it in another location, and didn't want to move it to where I'd need it for the modem. I didn't even realize a POE injector existed, so just happened across it. Since the 5G modem doesn't give me speeds over gigabit, this looked like a great solution.This literally was pretty much plug and play. Nothing special. Just plugged in the power cable, attached one end to the POE modem and the other ethernet jack to my LAN. The injector is clearly labeled, so it's really easy to determine which port is what. The instant I plugged in the POE modem, it fired on up, and began working. I didn't lookup the power requirements for the modem, but clearly 15W is enough to power it. It's been working great ever since. At this point, it's only been a few days, but this really is a great solution.Price wise, under $12 is hard to beat for this, making it an even better option in my mind. If you're in the market for a smaller option versus a switch to power a POE device, this is one you should definitely look at.

I used this with a POE to USB C PD supply.edit: I've since bought the 30W version. It has the same outer case, different sticker. I don't feel like cracking it open, but I did compare weights. The 15W was 107g (including the glue I added), the 30W is 129g so there's certainly something extra. The rest of this review applies to the 15W version.My PD supply could draw up to 23W which is too much for this device, but it did let me see how it handled being overloaded. It actually ran at 20W for 10-15 minutes before it started resetting. It would come back up and reset almost immediately after that. The device was warm, but it didn't feel extreme.Efficiency is OK, not great. Some examples at 20W output (yes, this is over maximum) it drew 28W from the wall. A more reasonable load of 7W drew around 11W from the wall. Being a low power device this probably isn't too bad.The hardware seems pretty nice. The circuit board looks like a quality design. It has expected protection components. The high-low voltage separation looks great. Capacitors, inductors, and transformers are all siliconed in place nicely. I don't care for the included cord. It's quite thin, and marked 2x0.5mm². Adequate, but I'm used to bulker cords that are better protected from cuts and abrasion.When running with the case open temperatures peaked around 45C (with a normal load). The hottest components seemed to be a couple different diodes, and the main transformer. I didn't see any issue.

POE Injectors don't need bells or whistles, and while this device doesn't have anything fancy, it does what it needs to do well. It powers up my cameras without complaint, and the network connection through it is very reliable.My only complaint is that the A/C power cord feels just a bit thinner than I'd like. I know it's carrying a fraction of an amp, but I'd still feel better with just a little bit more conductor.

This device only supports higher voltages I could not get it to work kn 12v security cameras. A little frustrating, if I had known it did not support 12V I would not have selected it.

I ordered an inexpensive IP camera to provide persistent surveillance of my office front door. I didn’t want or need a NVR to power the camera, I just wanted the camera to connect to my office network. I needed an easy way to inject the power into the RJ45 cable. This was a simple solution. There are basically two designs of this type of device. One design integrates the power plug into the case and the other one has a power cable that attaches to the box. If it is convenient to run the RJ45 cables to and from the power outlet, the first option might be better. But if you don’t want to run the cables to an outlet, this design gives you more flexibility to place the RJ45 jacks in the location you want and then run power to the box. This device worked great for me and was a convenient way to get power to my camera.

The YuanLey Gigabit PoE Injector worked very well for my installation. I have a new wired camera on my property that I needed to get power/data to. In my backyard area I required a PoE injector and this worked out quite well. There is really no setup required, you just need to connect the RJ45 cables properly and connect the power.I had already set up my camera, so this was very easy to put in place. Once I verified network connectivity and power to the camera - I let the unit run for a period of time. I did not notice any problems with heat or any issues with camera power or communication. This was perfect solution to getting my camera online.

You have to guess which port is PoE and which is LAN because despite the listing pictures showing you it is labeled, it is not. This is not for heavy duty loads, it can only power up to 15w, but on a basic setup, it works just fine. I'm letting my PoE switch handle the majority of my setup, but this is working for a small setup on the other side of the house from my PoE switch.
