I have a cnc router in my shop that has a high frequency drive on it. I have not noticed problem in charging my iPhone over the years but I did not do it often. But I have been paying this online game on the way to work that eats my battery and I wanted to top off my phone while eating lunch now that I have a bluetooth headset I don't have to use the external battery to charge I can just plug in the phone. But I noticed if I have my phone or ipad plugged in the screen is spastic when I touch it. first I thought it was the no name charging cords but a apple lightning connector did it too thought it was the cheap power block nope apple one did it too. took the block out of my shop and it is fine. when my my machine is not cutting it is fine.
even my UPS does not dampen the noise. any idea that does not cost a lot to stop the noise?
