For smaller draw devices it may work fine. I powered 2 Unifi ac lites via Poe with a 25ft and 50ft flat Ethernet cable for a couple years, no problems.

I am glad that worked for you. The reason I flag it is: it may silently appear to work, but be heating up the cables without you realising it.

Oh no, yeah I made sure that wasn’t the case with my setup. Monoprice 30awg flat Ethernet cables in 25-50ft with a 6.5w power draw from the devices, no heat at all.
