TP-Link PoE Injector Gigabit | Non-PoE to PoE Adapter | 802.3af Compliant | Up to 15.4W Power Budget | Wall Mountable | Plug&Play | Up to 100m(328 ft) | UL Certified(POE150S)

Works well! Solves a much needed problem to power microcontrollers in so many places. I love that it has different voltages, just check the voltage (5/9/12) switch before plugging in!

Item functions exactly as described. Powers my connected device with no issues.

Setup is simple, plug it in and you are done. My cable runs are between 50 and 200' long and this PoE injector works perfectly. I get great throughput. If you need to install a device in a location where a power connection doesn't exist, this makes that simple. Install your ethernet connected device, plug this in and you are done. As with any PoE connection, if you are trying to run high energy requirement switches or things like that, you should first check to see that this will provide enough power to run it. Setting this up takes less time than it takes to unpackage it from the box. Everything is included. Here is an installation tip, for maximum benefit, locate the adpater's power cube closest to the target device where power is available. Even though you can send power a long distance, like anything, the shorter the distance you need to transmit power the better. Remember, this is DC power, it will not power an AC device and the device you're trying to power must be PoE compliant. I really like this solution better than PoE routers because if you get a bad PoE port on the router, you are done, that port is no longer available. With this solution, trouble shooting is simple. If one run goes down, you can immediately check to see if the PoE is the trouble or the device your're trying to power has the problem. Just run an extension cord so you can use the regular power adapter and bypass the PoE injector. Then you will know immediately where the problem exists. I bought three of these and they all worked perfectly out of the box. If you have a WiFi access point or other PoE device that needs power this injector should work just fine. One caveat: Make sure your cabling is up to par. If you have old cables that have problems, this isn't going to fix that. This will work over Cat 5 Cat5e and Cat6 cabling. A lot of times when you read that someone is having problems with networked equipment, faulty cabling is right up on the list of other problems on that network. Always test with a known good cable. Bottom line is that this injector works just as described, has great throughput and is reliable to the maximum distances claimed.

Compact, good looking units, working well for me! At first I ordered the individual units (injector & splitter) but then noticed they are available as a "kit" for less money, doh! I then ordered the kit too thinking I would return the individual pieces. However, on the kit (POE injector+splitter) the units are white plastic, are 10/100 only and non 802.3af compliant. The POE injector and splitter when ordered separately are black plastic, are gigabit and 802.3af compliant. Seems very odd. POE injector comes with the 48v adapter. I ended up keeping all of them. I needed to connect 2 building that are 150 meters apart with a CAT5e ethernet cable. The maximum cable length for ethernet is 100 meters. So I needed to divide the 150m into 50m and 100m sections then add a switch at the 50m mark. However there is no AC power anywhere between those two buildings. I used this TP-LINK PoE injector & splitter kit with the PoE injector placed at the beginning of the cable, the splitter (which acts like a switch) placed at the 50 meter mark powered from the PoE injector and the ethernet cable continues on for the last 100m. I don't use the 5/9/12V output for anything. I used the white units from the "kit", everything is working very well. Saved the black gigabit units for spares, might upgrade to the gigabit ones if client needs more network speed.

Using this to power a Unifi NanoHD access point. Seems to work fine, plug-and-play. I used this because the OEM's own version was out of stock and/or was more expensive after shipping. Connections are clean, there's a link LED. The drawbacks to the design are a relatively big (unnecessarily) AC adapter, and no wall-mount bracket. That'll limit installs outside of SOHO, and even at home means making sure there's enough space for it. Overall, it suits the need though it's not perfect. TP-Link is one of my "trusted" brands, but I'll update if the injector fails unexpectedly.

It fit. It seems to function fine.

Positive: It's a dead simple and easy to use product and does EXACTLY what it says and is advertised to do. Cons: None. If you know what you're buying and you know what you're doing then you won't have a problem. A PoE injector does exactly what is says. It INJECTS voltage into a RJ-45 cable to combine your data source with voltage which, in turn, will allow you to power a PoE device such as a wireless AP or PoE camera at the other end of the RJ-45 without the need for a power source for that device whereever the cable terminates. A PoE SPLITTER on the other hand does the OPPSITE! Of course it doesn't come with a power supply in the box like one of the reviewers left a negative review for. WHY WOULD A PoE SPLITTER COME WITH A POWER SUPPLY IN THE BOX!? My god man! You use this device for splitting the data and power that is already in your PoE injected data line. You can then run the power into a device that isn't PoE powered and the data into whatever you need the data for. An example of this would be APs that are not PoE powered. You don't have a 120V outlet where you want the AP, but you have a PoE powered data line. You place a PoE spitter there and run the data into the AP and use the dc barrel of the split voltage to power the same AP. Job done. I use these PoE splitters not for the data part, but to split out the DC power to be used to power some 12V 1A IR Flood lights to assist the PoE cameras at the same location that are using other PoE data lines. There's no 120V power there, but these splitters allow me to power the IR flood lights with the data lines that were already run in the past. Just have the lines plugged into a PoE switch wihtout data at the other end.

I read many reviews on different brands of PoE injectors, and I decided to go with this one. This is a great little device that does the job that it was designed to do. I brought 3 of these injectors to power my PoE surveillance cameras around the house. Although this supports gigabit, my cameras and switch are only 10/100, so I can't comment on the speed of that. However, the data transfer rate seems to be pretty consistent. I have had these injectors for a two months now, and I haven't experience any data signal drop or power failure. And of course, they are ON for 24/7; they have been reliable. Depending on the location you put the injector, the unit doesn't feel hot to touch, only warm at most, which is normal. There is really not much more I can say about this injector. If you are looking for a PoE injector to power your surveillance camera, look no further, I would definitely recommend this one. My only complaint is that, the ethernet cable that comes with the injector is only 3 feet long, and it is too short for any of my camera setup location. But then again, for the price, it was still a very good buy. I brought some longer cables on Amazon, no big deal.
