Power sockets with built-in usb charging ports also emit a fair bit of RF interference - we had to move the kitchen radio because of it.

- hunta2097 6y agoUngrounded (floating) switching power supplies can emit a lot of high frequency noise. Unfortunately this is the majority of PSUs these days.
- H1Supreme 6y agoRan into a problem in my studio (audio recording) earlier this month because of a powered USB hub with charging ports. I kept getting this faint rhythmic ticking noise in my guitars. I stripped down, and rewired everything in my studio to track it down. Not sure if it's the PSU, or something USB specific. But, as soon as I unplugged it from the surge protector, the noise vanished.
