Why is there a noise when charging?

Because it is engaged in the power adapter industry, so often have friends to consult me about charging some aspects of the problem, some time ago a friend asked me to say that his cell phone charger charging sound, I do not know if it is broken. Then why the power adapter will have sound when charging it, this phenomenon is normal next EAHUNT for you to briefly explain it.

Power adapter in the Zizheng is an inductor coil in the alternating current through the magnetic field due to the effect of vibration of the sound, generally good inductor sound will be smaller (enameled wire winding encapsulation process over the top), but there is sound can not be fully equated with poor quality. As long as the sound is not particularly large, such as two or three meters away can be heard, then there is generally no problem.

Inductors generally use paint sealing, epoxy resin, heat shrink tape and other ways of encapsulation, over time these encapsulation materials may be loose, the coil itself will be subjected to thermal expansion and contraction of the role of the gap, so over time it will be sizzling sound.

But this process should be gradual, usually after a long time before the sound is slowly big. If it is suddenly found that there is sound, or the sound is big and small, then it may be the inductor upstream device short-circuit, or inductance and other originals have contact with the phenomenon of abrasion, which is likely to lead to the danger of the situation.

Each product 100% through the aging test, to ensure that the product qualification rate of 99.99%, to meet the 10,000 times plugging and unplugging without failure standard.
