Legrand adorne 2.1 -Amp 125-volt Residential Square Full USB Receptacles , Magnesium
I have 4 of these installed. There is a "high pitch" type noise coming from them when nothing is plugged into them. Has anyone experienced this?

Thank you for your question regarding Legrand Adorne 2.1-Amp 125-Volt White Indoor Square Wall USB(Model # ARUSBW4). The humming/buzzing noise is a common characteristic of the class 2 power supply but it should not be load enough to be of a nuisance.
