There was still a VERY SLIGHT high pitched noise coming from the unit, but I had to put my ear right next to the charger to even hear it
-
I noticed a few other reviews mentioned the high pitched noise, so rather than getting it exchanged, I think I will find another brand
-
Reduced to 3 stars due to the noticeable coil whine (high pitched noise) that comes out of the charger whenever a laptop is plugged in
-
Returned two of these because they made a high pitched noise while charging my Essential Phone

One was emitting an annoying high-pitched noise
-
This adapter seemed pretty handy for solving the "I no longer have any USB charging capability on my Macbook Pro" problem

, I love this b/c the two-prong plug fits into a converter with no issue and you can also use it with a standard extension with the requisite plug if necessary
