Powering it via 24V passive PoE while also powering a Unfii AP via PoE passthrough really simplified the cabling requirements.

I'm powering it with the passive POE injector that came with my Ubiquiti wireless AP, with the AP connected to eth4 which is in POE passthru mode - works perfect.

Easy setup and POE pass-thru is a plus.

and they told me I should just use the POE injector which irritates me since this is a feature that does not work!Unifi

Does not support POE to a Unifi AP

These are fast, convenient (if you're already deploying 24V passive POE), tiny, and robust

The passive POE pass through feature on one of the ports is also very nice; what is perhaps a bit problematic is that as far as I know, passive POE is not fully standardized, and I am not sure it would work with the splitter I currently have at the other end

Passive 24V POE that powers my Unifi Lite

this didn't support 802.3af PoE, but other than that I was blown away by the value

The PoE on this is extremely convenient, especially when paired with a Unifi AP - plug in the injector, connect to the router, enable PoE for eth4 and connect your UAP and you're in business.
