I needed to put a Raspberry Pi at the end of an ethernet cable, there were no power outlets nearby, and my switch needed something that could do proper 802.3af. This is the answer. Oh my god is this the answer. If I ever met the person at Wifi-Texas who decided to make this a thing I would embrace them in a long and awkward hug.You never know you need it until you need it.I heart you, Wifi-Texas.
