In this article, we’re going to look at the best POE injectors. PoE stands for power over ethernet, and devices (phones, access points, etc.) can actually be powered by a Switch. However, if you didn’t buy a Switch, you’ll have to purchase an injector if you’d like to power these devices (or a new switch, which can be more costly).

What is a PoE Injector?
A PoE injector is a device that will allow you to connect a power-over-ethernet device to a switch that can’t power it. It sits in the middle of the switch and the device and comes with a power cable. After the device is plugged into an outlet, then the ethernet cables are plugged in (Switch > Injector > Device), the device will receive power.
This means that you can take any switch that you currently own and power a device. Just keep in mind that you must have power!
What are the Best PoE Injectors to Use?
When looking at the options below, please make sure that the total power output and distance is sufficient for the device that you’re trying to power!
Ubiquiti PoE Injector
The Ubiquiti Injector is an option that most people using Ubiquiti hardware will be interested in and will be one of the best injectors for those types of users. A few important notes are that it only utilizes 15.4W, but is great for most UniFi cameras and access points.
In general, you should really only purchase this device if you are currently running Ubiquiti devices and want an injector from the same manufacturer.
This isn’t really a great value or even something I’d recommend, but I will say this: when you have a UniFi network, most people buy all UniFi equipment. This is the only scenario where I think something like this makes sense and why it’s on this list…and to be clear, even then, you’re better off with one of the devices below.
The TP-LINK TL-PoE150S is a 1GbE injector that will supply 15.4W of power at 100M (328 ft.).
Please keep in mind that this device cannot power a device with more than 15.4W, please check out the options below!
Simply put, this is an awesome budget option that will be great for things like security cameras that use a small amount of power (up to 15.4W).
The TRENDnet TPE-115GI is a 1GbE PoE+ 1GbE injector that will supply 15.4W or 30W at distances up to 100M (328 ft.).
It has a wall mountable design and auto senses the device that it has to power (meaning it will use the correct amount of power depending on what device is connected).
This is a good, usable Injector that has enough power for 30W devices and is a great budget option. For the majority of devices, this will be more than enough power. To put it into perspective, the security camera that I use which has two total LED lights only uses around ~15W of power, so this is double that.
The TP-Link TL-PoE170S is a 1GbE PoE++ that delivers up to 60W of power at distances up to 100M (328 ft.).
This device is plug-and-play, meaning that you simply plug it into your switch, then plug the other end into the device (as well as ensuring the injector has power), and it will automatically send power to your device!
This is the device that most people who need to power (up to) a 95W device should purchase. It has more than enough power for almost anything, but if you really need more, check out the device below.
The TRENDnet TPE-119GI is a perfect device for situations where you need a lot of total power. This device is a 1GbE device that supports PoE++, with a total power delivery of 95W at 100M (328 ft.).
If the device you’re trying to power needs close to 95W, this is a great device. However, most devices will require significantly less, meaning you can go with one of the other options above.
This is the most powerful device on this list as it supports 95W and has more than enough power for most needs. If you need to power something like a PTZ camera (that uses a lot of power) or a secondary Switch, this is the one.
iCreatin 2-Port Injector
The iCreatin PoE+ injector is a 2-port injector that supports up to 35W of total power. It’s not particularly unique and is a generic injector that can be used up to 100M (328 ft.). However, it does have the benefit of having two power-over-ethernet ports in one device, so if you need to power two devices and will be able to fit it within 35W of total wattage, this is a great device.
I like that this device has two total power-over-ethernet ports. In many circumstances (especially with things like security cameras), you’ll need to power multiple devices and if you’re not purchasing a Switch, this will be a great option.
The Texas WT-AT-4 is a device that will give you four power-over-ethernet ports in an individual injector. This device has a total power delivery of 60W, though it’s limited to 15W per port.
If you already have a Switch that’s fulfilling your requirements, but you’re looking to add powered devices to it, this is a great option. With that said, depending on requirements, it might make sense to purchase a dedicated switch.
This is the most interesting device on this list because overall, if you need four total power-over-ethernet ports, you should really consider buying a PoE Switch. With that said, there are going to be certain scenarios where this power-over-ethernet Injector makes sense.
Conclusion & Final Thoughts
This article looked at some of the best PoE injectors. An injector is a great option for anyone who needs to power a device and doesn’t have a Switch. In cases like this, it’s generally significantly cheaper to buy one or two injectors to fulfill your requirements rather than an entire switch.
However, once you get to a point where you’re looking to power three or more devices, it makes sense to invest in a quality 8-port PoE switch.
