240V AC and 5V DC manage to live close in a charger without problems. Problems with quality does not depend on voltage. I love the concept of PoE with one exception that it requires constant 1W or similar load to work even if it is not needed for low power device.

I mean, yes and no. My laptop case is at 78VAC to ground right now. It gives the tingles. I don't use my laptop much while plugged in. They all skimp on making proper 3-pronged chargers these days. My desktop has a grounded case and doesn't have this issue.

My phone, when plugged into wall AC, the touch screen stops working because the whole phone is at an elevated potential and it messes up the capacitive sensing.
