High pitched whine coming from these chargers.

Mine makes a high pitch whine at low loads and is also picky about working with certain lightning cables.

Love the size, but it emits a high pitch whine audible to my older ears which makes it too irritating to use even when I plug it in inside my center console

Started emitting a high pitch whine after 6-9 months of use.

: I originally wrote a 3-star review (below) based on the fact that while it worked, it had started emitting a high-pitched whine

Only complaint is that after a bit of use it tends to emit a high-pitch whine whenever a cable is plugged in

Under load, it now emits a very high-pitched whine somewhere north of 10kHz, which I can't handle for more than a minute or so

I usually well charged my phone at home or at work before going anywhere else; which means I don't normally need to utilize it

n’t have USB ports or even an auxiliary input, like the car I just got rid of.
