Single-Port Mode A Passive PoE Injector, 48V 15W

Provides PoE for devices that need it.

Great quality at a good price. Works as advertised.

I can’t say enough about this thing. First off, the company behind it makes some amazing products—I use their gear in multiple places, and I’ll get around to reviewing those later. But right now, we’re talking about this little mini POE injector. And I do mean mini. Every once in a while, something comes up where I need a POE injector, and usually, they’re these bulky bricks with a separate power cord. Not this one. It’s compact, efficient, and ready to go when I need it. And at this price? It’s a steal. Most POE injectors cost 3, 4, even 10 times as much. If you need a quick, no-nonsense POE solution without the bulk or the high price tag, this is the one.

Works as advertised

Quick installation

I bought two of these to power two new Ubiquiti UniFi 6 Lite WAPs I bought. Ubiquiti PoE adapters were out of stock, so I tried these out. They seemed to work fine... at first. Within a week or two I started getting strange problems on my network. Backup scripts that used to take 45 minutes were taking 3 hours, and I kept seeing "Error 59" popping up from multiple programs. My WAP data transfer rates kept dropping over the next month and then developed spotty connections. Soon after my network audio player started developing static... and after hearing a loud static burst right after I sent a WAP reprovision command I realized that it was the PoE leaking power onto my ethernet. I swapped these out for the much more expensive Trendnet PoE+ and all the problems stopped immediately. You've been warned.

Works great

I bought this in June and it stopped working in October.
