As a commonly used mobile charging device, charging treasure is always used when using mobile phones and tablets, but news about the sudden explosion of charging treasure may have been heard by many people. Generally, the regular charging treasure will not explode for a long time. If the defective product does not rule out this, it will explode. Therefore, when purchasing the charging treasure, you should choose the high-quality products of the regular brand. When using the charging treasure correctly, please be careful not to charge for a long time; unplug the power supply when charging is completed; place it in a ventilated place to avoid sun exposure; avoid heavy pressure and strong vibration; do not pour water for fire.
Charging treasure will explode when charging for a long time?
1. Regular charging treasure will not explode for a long time, because there is a charging control circuit and a battery protection circuit inside. When the battery is fully charged, it will automatically stop charging and cut off the charging current.
2, the defective product does not rule out this may explode, but in actual use, the battery manufacturer has already done preventive measures inside the battery, so there is generally no explosion.
Charging treasure suddenly exploded
In principle, if it is regular and there is no impact, the charging treasure that damages the charging protection will not be so easy to explode, but charging for a long time will cause the heating circuit board to catch fire, and the charging treasure will explode for the following reasons.
Charging treasures are basically divided into two types, one is the battery of 18650 lithium battery; the other is the battery of polymer lithium battery. The battery cells of the former are generally carbon core batteries, and the price is low but the power is small; the latter has the advantages of large power, fast charging and discharging, and more safety.
In addition to the quality of the battery, the circuit board at the interface acts as a commander, and can direct the charging treasure that is being charged to determine how much power to continue to send based on the amount of power that has been charged to the battery. The voltage of the electricity is not to be adjusted. In order to save costs, some manufacturers use the quality of the circuit board, and even the self-regulating function is not available. Therefore, we will find that the charging treasure will emit smoke and explosion during the charging process.
