The voltage is unstable, and when a large current is suddenly passed, it will cause burning. It may also be caused by the charger, which may cause burning when the current standard of the charger is not the same. When the phone charger has a burnt smell, it is necessary to power off immediately to avoid damaging the phone.
Note 1, do not charge after a full charge if the phone is fully charged but still connected to the power supply, it will affect the battery life. That's because once the phone reaches 100% charge, it goes into \"trickle charge\" mode - remaining fully charged. If you continue to charge, the mobile phone battery will be affected by current, and some chemical components will be destroyed, affecting the efficiency of use.
2, do not charge to 100% In fact, lithium batteries do not need to be fully charged and then power off. This is because after the phone is fully charged, the voltage inside the battery will rise, increasing the battery burden. Therefore, mobile phone charging can be completely plugged in and out, as long as it can maintain normal use.
There is only one possibility in this case, that is, there is a short circuit in the internal circuit of the charger, and the plastic case is burned, so there is an unpleasant smell.
instable voltage
The voltage is unstable, and when a large current is suddenly passed during charging, it will cause burning.
Current difference
Caused by the charger, the current standard of the charger is different, which will cause burning.
Charger short circuit
The internal circuit of the charger is short circuited, and the plastic shell is burned, resulting in an unpleasant burning smell.
Replace as soon as possible
Chargers with burnt smell is dangerous, indicating that the charger has a serious problem, prone to fire, should be replaced as soon as possible the appropriate charger.
