Summary: I run my rt-n16 slightly underclocked (400MHz) for power an longevity. A kill-a-watt on the wall wort shows it typically draws just under 6W, so there's a decent amount of headroom for what this PoE setup can provide.
Pros: Coupled with the TPE-111GI, this seems to have no problem powering my Asus rt-n16 router. Now I've got all my core network components on the same UPS. Comes with two DC power adapter cables.
Cons: I wish the data out cable was was just an rj45 socket so I could replace it if needed. However, it's a much more sturdy cable than the product pictures would lead you too believe. I don't expect it to be a problem.
