This crackling is usually seen on low-end or counterfeit chargers whose sound insulation and the quality of the materials used leave much to be desired. It can also appear as a result of natural degradation or light desoldering of a component in the charger. Note that in this case, the phenomenon does not present no risk for you and it does not affect the lifespan or performance of your charging device.

Indeed, the crackling can then come from a false contact or an electrical failure and eventually lead to a .
Note: If your charger sizzles very strongly or becomes more and more intense, unplug it to avoid any risk.

What to do when your charger sizzles?
In this part, we will help you understand and find the origin of the crackling noise to then help you find the solutions adequate to remove it.
Check the power source
The first thing to do when your charger sizzles is to check that the power source, and therefore more concretely the socket to which you plug your charger, is not the cause of the failure. Indeed, voltage problems or a faulty electrical installation can cause the appearance of this parasitic noise. Although this malfunction is much rarer, it is necessary to verify it because it is the most likely to cause a . As a result, it presents the most risk to you or your material.
For check the charger's power source which sizzles, it's simple. Connect your charger to another wall outlet in your home. If the buzzing continues, the problem is not with the electrical outlet.

Check the condition of the sizzling charger
When your charger sizzles, it is very likely that the problem comes from the USB adapter or the charging cable. More concretely, it can come from a bad contact caused by damaged electrical wires or charger connectors; but also a poor sound insulation or an mechanical resonance related to low-end materials, assemblies or components present on your charger. This second hypothesis is particularly likely if your charger is a counterfeit or cheap.
To test your charger, simply plug it in with another compatible device. If the noise continues, then the problem is with the charger. On the other hand, if the buzzing stops the problem comes either from an incompatibility between your charger and the device being charged, or from the USB port of your device while charging.

Check the power connector of the device being charged
If you hum problem on your charger does not come from the power source or charger, then it may be that the power connector of the device being charged (PC, phone etc) is involved. In this case, the noise is most likely due to poor contact between the connectors of the charger and the receivers (pins) of the charging port. This false contact can then come from dirty pins which disrupt the transmission of current or worn pins who no longer fulfill their role correctly.
First, try to clean the power connector using a suitable product (see your user manual). Never use an abrasive product or a product with water to clean it. Be careful, be very delicate when handling because the receivers are extremely fragile.
