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)

It fit. It seems to function fine.

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.

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.

Worked perfectly. Gave me the voltage I needed for the device without problem. The only downsides (and the 4 star rating) has to do with aesthetics. First off, the line in and line out are on opposite ends of the injector so you have to have it in a place where a cable can come into both ends rather than both cables coming in on the same end and slipping the device up against a wall. In general, it makes it harder to place the device somewhere where it can sit without getting knocked off. The other issue was the power supply to the injector. It is not shown in the pictures, but it is a horizontal rectangular power supply with the prongs perpendicular to the body. If you have a typical power strip, plugging one of these in will block at least 3 outlets in addition to the one you are plugged into.
