When I charge my brand new note 10 plus in my car using a third party car charger, the phone emits a very high pitched noise while it's charging. 

The noise seems to be coming from near the top of the phone. It's an extremely annoying and intense sound. 

Has anybody else had this happen?

I have just bought an S10, previously owned an S8.

Same issue, tried the genuine Samsung cord in my $75 Battery Pack, but the sound was ear shattering.

I immediately took it off charge and plugged it into the wall with the Samsung charger out of the S10 box, the sound didn't occur. I tried again with the pack, but after 2 seconds the ear piercing sound resumed.

It stopped immediately after removing the cord from the phone.

I presume it's a "cease and desist" warning sound.

For whatever reason, the S10 doesn't like the battery packs, the S8 had no dramas with either of my high-end battery packs... guess an upgrade isn't always as good as the old.

 

* Side note: It's definitely not as good as the S8's in general.

Very disappointed. *
