I received this wireless power bank (PB-Y32) a few days ago and it makes noise while wireless charging. It’s a fast ticking sound that only happens while wireless charging. I’ve tried multiple different wireless phone devices and it makes the sound for all of them while wireless charging. I have no other problems wireless charging other than the sound. I wanted to place this besides my bed side and wireless charge my phone while sleeping but the sound is an annoyance. Is there any fixes to this or should I get a replacement? I am still within amazon’s 30 day purchase return policy.
