Tech Gigabit Power Over Ethernet PoE+ Injector | 30W | Plug & Play | up to 325 Feet

Great quality product! Works exactly as described, packaged very well, easy to install, super fast and very well made.

Works perfectly

works great! powered by cisco IP phone flawlessly.

Works as expected, Standards based. Good value! PoE started years ago as a hack with people putting 12 to 68 DC volts on the unused wires in the Ethernet cable as needed for custom ad-hoc applications. I wired up several such custom injectors 15 years ago for roof-mounted can-tennas and other projects. The classic injectors were super simple, and could be made from a pair of RJ45 jacks and a few inches of spare Cat5 cable. But it was not a consumer ready technology! - We always had to be carefull with the powered end, to not accidently plug it into an unsuspecting NIC and fry it, also we couldn't get Gigabit speeds as Gigabit requires all four pairs. Fast forward 15 years, and I'm wiring my house with surveillance cameras. I am so thrilled that now we have a Gigabit compatible PoE standard! The standard is safe for unsuspecting devices such that if I were to accidentally plug a powered end into my laptop, it will not fry the NIC with 48 volts! Additionally all four pairs can be used for data and power making the power transmission more efficient, and the data 10x faster. Running a single inexpensive cable to get reliable power and hard-wired data reliability is so much easier and the result so much more reliable than the alternatives (flakey jammable wireless signals, battery powered devices or running TWO wires - uggg! no thanks!). This device has worked great for my camera ( GW Security VDG2040IP HD Network ONVIF PoE 5MP 1080P Security Bullet IP Camera (White) ) Also, it is "compatible" with (but not compliant?) with the 802.3at ("active" or smart) PoE standard. Since i can't see much of an overall price difference between "passive" 803.2af devices and "smart" (803.2at Type 1 or 2) products, I would definitely recommend the smarter "at" devices (like this product) over the older passive "af" standard. Of course the newer "at" devices are compatible with "af" devices, but a mixed pair is limited to the lower power and slower data speeds of the older standard. However, If you need more than 13 watts for the Powered Device (PD) get a "PoE+" device (802.3at-2009 aka Type 2), which I don't believe this device is. This product's description and title do not call out "PoE+" specifically, although 802.3af/at "compatibility" is claimed. This leads me to believe that this is likely an "802.3at Type 1" device which claims to have some extra power to spare beyond the 15W minimum. It works great for my Camera, but if you have a larger PTZ with defrost/ice-melt or some other device that needs a full 25-30 Watts at the device, get one that specifically claims "PoE+" or "Type 2" or "802.3at-2009" like TRENDnet Gigabit Power over Ethernet Plus (PoE+) Injector, TPE-115GI . I'don't know why many of these product listing are (purposefully?) so vague. If I were buying again I would stick to listings that clearly identify their claimed standards compliance rather than just claiming to be "compatible" with the standard, and claiming the wattage of the higher standard which it may or may not actually implement. I would get a product that specifically claims _compliance_ (rather than "compatibility"!) with "802.3at" Type 1 (13 watts) or "802.3at" Type 2 (25 watts). There are other devices ( TRENDnet Gigabit Power over Ethernet (PoE) Injector, TPE-113GI ) that more clearly state their capabilities. Being more confident in what you are getting is better than trying to save $10 on a Type 2 (30W) but actually spending $4 extra on a Type 1 (15 W). It doesn't actually claim to be PoE+ but lists the same 30W capacity leaving you to assume it has the same capabilites of the other devices that list 30W when that may not be the case. This product may be somewhere in-between - I don't have test equipment, but next time I shop, I'll reward the more precise and specific product listings over the ambiguous ones.

In my mind, it's hard to go wrong with a port injector...but it has been noted to happen. I work for a major CC company and I needed this to power on an Ariuba 274 wireless Access Point as one of the requirements was to have 802.3at as a POE power source. I can say it worked like a charm and powered my device on. I have used an 802.3af device before and have been using it to power a device off a standard desktop switch for about 1-2 months now and it's presented 0 challenges. One thing to consider, I have run into issues where you have a port injector plugged into a managed switch (Cisco) and sometimes, the power injector and switch don't speak the auto-negotiation, so you have to manually set the speed....this wasn't the case for me. PLUS it's gig speed. 5 Stars due to all of the above...I will buy again if I have a need. I might even try their line of multi-port injectors, if they have some available. For what it's worth -- the item comes packaged in a standard ESD bag, almost a basic brown box...and got here in the time it said...but honestly, I bought this for how it works, not the packaging.

I don't know a ton about POE and just saw different W ratings . . . 30W, 60W . . . I figured maybe the voltage was different on higher watt units but it didn't really way. This one worked with the puck style unifi Access Point, the Wifi 6 version whereas the unifi branded one didn't work. They were both 30W and I didn't look beyond that to understand the difference. I just returned the unifi one! And generally I won't buy unifi anything anymore but that's a different review!

My review is based only on my situation, and it probably has nothing to do with the actual capability and performance of the PoE in the operation that it was intended. However, it did not work as I had hoped. I am not familiar with PoEs in general and had to search information on my existing one that I am using to power and antenna for fixed wireless on my roof. I have attached a picture of the existing PoE that I had intended to replace. Now, with all of that in mind, I couldn't really find the info I needed, so I had to extrapolate what I could find and apply it to the PoEs I could find. Obviously, my extrapolation was woefully deficient. So I am going to ask those of you who are familiar with these devices, what product could replace the PoE I have, based on the picture I have posted here with my review. I asked a question in the question section above, but I did not provide enough information in it to get an adequate answer, so I'm hoping I can get a comment that will help me in my search of a POE sufficient for replacing my current one. I have already bought three, and this is the first midspan of them, so I thought it would work. Thanks so much and I hope this might help someone who's in my situation who doesn't really know much about PoEs and is looking to replace one for a fixed wireless radio on their roof.

I now have two of these that I use to power a Foscam outdoor IP camera, and a Ruckus wireless access point. I have a small 8 port switch with 4 PoE ports, but the switch can only supply a total of 30W, which limits me to two Foscam cameras. Since I discovered that, I now prefer to use these individual PoE injectors--it's easier to add new PoE devices with them vs. buying a much larger and more expensive PoE switch. The PoE injector is as simple as a basic power supply--just plug it in, and it works. The power cord is a thick 3-prong cord just like a standard PC power supply cable, so it isn't something you can easily hide. And the PoE Injector itself is larger than a typical 'brick' style AC power adapter, so you will need some place to stow or hang it. There are screw mounts on the back of the injector, so I was able to hang them up on the wall out of the way. And the sides of the injector have a plastic 'tongue and groove' on them, so you can slide several of them together to make one big block, which is handy. The device works great and has powered my smaller PoE devices just fine.
