My DJI Tello battery Charging Hub occasionaly making a high pitch whining noise. I tried diffirent cables but no luck. When I plugged it into an extension wire outlet it makes the noise but if I plug it directly in the wall it somtimes doesn't make the noise. I'm using a 5v 2amp outlet plug and a wire that supports the same. If I place the wire completley straight, then somtimes it doesn't whine. What could be the problem?
