Is PoE more efficient than plugging in adapters for each network device?

And at what scale does it start to matter?

From my perspective; I’m going for a 3 node mesh router, plus 2 switches, and was considering if in 5 years time the electricity difference would be less than the extra upfront cost. The absolute max length of cable would probably be around 30m

    Dc-Dc is pretty efficient, I wouldn’t worry about conversion after the initial 48v, but I would potentially worry about losses in poor quality home wiring on longer runs in bigger homes
