Does not seem to work with all POE-at devices
I bought this POE injector to power a Wi-Fi 6 access point (AP).
This AP requires a POE-at power supply but when it's behind this Ubiquiti injector it tells me that the power supply is too low and assumes that it's a POE-af power supply.
Thinking it was my Ethernet cable that was of insufficient quality, I bought one that was POE+ certified (POE-at).
Failed, it hardly works any better (the AP lights up briefly)
What's more, this AP only consumes 6W (measured with a 'real' 12V power supply, even an undersized 9V power supply used by mistake is sufficient).
In short, the injector has been consigned to the scrap heap.
