Review (5/5): Works great to power the Echo Dot
I've used these POE adapters to hook up some Amazon Echo Dot's mounted to the ceiling and they've been up in my burning hot attic for a while now. Haven't skipped a beat!
I didn't use the power adapter that came with it. Instead, I plugged it in to my passive 24V POE switch. So really I'm just using the two ends with ethernet on them. Couldn't be happier for the money.
