Has anyone else experienced a rhythmic chirping from their MagEZ Slider? The first charger I ordered produced an audible rhythmic high-frequency electrical chirp around 120bpm. This chirp persisted the whole time a phone was not on the charger. I contacted Pitaka customer support and a replacement charger was issued. This replacement charger has no issue and produces no audible sound.
Because I was so satisfied with the working replacement charger, I purchased another MagEZ Slider for another room in the house but this second one is also producing an audible chirp exactly the same as the first one. Is this a known issue any others have experienced?
The chirp is a very high frequency and it seems it is not audible to every person’s hearing range. Video attached of the sound:
