Power adapter sparks when charging

Have you encountered a power adapter plug on the row plug unplugged with fire like? Under normal circumstances, manually plugging and unplugging the plug, if it is with a load at this time, it will be more or less a bit of fire, and at the same time, there will be a snapping sound as you said. The heavier the load (high power), the more obvious this phenomenon; the lighter the load (low power), the phenomenon is not obvious

Simply put, there is a voltage difference between the socket and the plug, the moment of contact will fire. The shorter the time of this contact process, the better. That's why you see that many places now use air switches instead of the old plug-and-play kind with fuses. Because the action time of the air switch is short, the ignition is small, and it is not easy to damage the contacts.

If the charging power is small, even if its battery is empty, then the charging current is extremely small and should not fire. It may be a problem with the power adapter.

　　Plugging the laptop a little fire is normal, but the normal situation will never top off the front air open. This situation has the following possibilities:

　　1, the laptop internal damage caused by having a short circuit (including battery);.

　　2, power adapter internal damage caused by a short circuit.

　　3, there is another situation, the socket is relatively loose, the contact is not firm, will also frequently fire.

In addition, it is recommended to develop good electricity habits, plug and unplug, try to operate with the right hand. In case of leakage or other accidents, the current will not pass directly through the heart, the danger will be much reduced. Use electricity safely, choose Eahunt power adapter!
