TRENDnet 65W 4-Port Gigabit PoE+ Injector, TPE-147GI, 4 x Gigabit Ports(Data in), 4 x gigabit PoE Ports(Data + PoE Out), Multi-Port PoE+ Injector up to 100m(328 ft.), Add PoE+ Power to Non-PoE Switch

I am using this on a Unifi Pro 24 switch to power a Unifi access point and will later add three cameras. The access point is performing properly with the TRENDNet injector. I could have gotten a Unifi Pro 24 switch with PoE installed for, uh, $300 more, but I only needed four PoE ports, so I did the math. I really like the magnetic attachment feature and I used it to clamp the injector to the bottom of the UPS supply in my expansion rack. Pardon the mess, I'll clean the wiring up when everything is installed and sorted.

I bought this to replace 3 Ubiquiti PoE injectors. The problem I had previously was that I had a US-8-60W, but you realize that it can only have a limited number of uplinks - at 1Gbit - without link aggregation. Any switch with PoE and a 10Gb uplink (yes, it's easy to get over 1Gbit via WiFi and other network switches down the chain) costs well over $200. It mounts well, the included magnets are SUPER strong, and it does exactly what it says - it provides PoE via 4 separate ports with each having their own input. It works PERFECTLY with Ubiquiti devices, I have 2 UAP-nanoHD and a UAP-AC-Lite, as well as a USW-Flex-Mini powered by it. No dropouts, no weird behavior, no restarting it because it stopped working properly - it's been on since purchase and simply works.

So far, this PoE injector seems to be doing the job. Currently running 2 APs @ 1Gb each. Haven't seen packet loss yet.

Works good for adding POE to non POE switches. There is no good way of monitoring it but definitely works in a pinch.

It's a well built, 4 port PoE injector. Now, as an owner of an IT company, you're doing something wrong if you need a PoE injector, but for low cost installs, the 500$ increase to a 48 port PoE capable switch is a bit steep if just 4 devices need it. The solution for that is of course a small PoE switch, not an injector, but sometimes they can't be avoided. In cases like that, these rock.

I bought one of these to power a few security cameras at a data center where we have no PoE switches. What I was surprised to find in the box with it were two screw-attached strong magnets you can choose to install on the bottom side of it. So, instead of an ugly zip tie job, or sitting it on top of something else and creating future problems, I was able to just magnet it to the side panel within the rack where it was most convenient to run the cables in and out of it. I've got the typical APC racks with the metal side panels. The magnets are very strong, so it does not appear to be at risk of going anywhere. I ran my laptop through it out of curiosity and had no issue with gigabit throughput, if you are attaching something to it that has real bandwidth usage vs typical cameras and things.

What else is there? Plug it in and use it. No problems at all. I love it when things work like they should.

If you don’t want to buy an expensive POE switch. This device is the way to go. It handles multiple APs with ease. It comes with a magnetic mounting plate also.

Acheté pour alimenter des caméras et AP Wifi, mon switch PoE Unifi étant au bout de sa capacité, fonctionne très bien sans aucun problème.

Günstiger PoE-Injector für bis zu 4 PoE-Geräte.

very good
