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

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

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.

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

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.

Purchased to power a couple of unifi inwalls and it works great, however, this unit will not power my mikrotik switch. Based on my research into the topic (was admittedly was not very thorough) This unit provides a more passive POE output and mikrotik switches expect a more non passive unit

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.

Delivered on time and worked as advertised. Very pleased with this product.

I used this to power 4 remote Raspberry Pi's (Through active splitters) and get rid of the wall warts. One nice thing about doing this, the low voltage warnings went away along with the CPU throttling on the 3B+ units.
