So, as my first wireless charger I decided to get the PowerPort Wireless 5 Stand and It is wonderful! A lot of what makes it wonderful is inherent in it being a wireless charger. However, I also enjoy having peace of mind knowing my phone/charger won’t overheat and having the ability to charge horizontally or vertically and with my case on, is all unique to this charger and frankly make it better than most in my opinion.
BUT! I have one tiny little problem (maybe not even a problem and just an observation), there seems to be a very faint oscillating high pitched tone coming from it. I only notice the noise when it is very quiet, and it seems to only happen when I am not charging my phone. Again, not really a problem but I am curious if that’s normal. Is it something all wireless chargers do? And what is making the noise? Or am I just going crazy (not to be ruled out)?
