Our teen son has a charger for USB that does the same.

I plugged it into a power strip with a "transformer" outlet
(not the new once that merely make room for a wall-wart but
a small isolation transformer inside the strip) and all of
the powerline RFI went away.

Is anyone aware of power strips that contain effective filters
to block powerline RFI?

Has anyone evaluated common (350-650) UPS devices for RFI filtering?
