The hazards of not unplugging mobile phone chargers

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.15
If the mobile phone charger is not unplugged, it may lead to prolonged charging, consumption of electricity, resource waste, and is not conducive to energy conservation and consumption reduction; It may also lead to prolonged electrification, aging of the charger material, causing voltage breakdown and other phenomena, which can seriously cause short circuits, accidental electric shock, fire, explosion, and other hazards. Here is a specific introduction:



1. Causing resource waste

When the charger is not charging, it runs at no load and its internal circuit board is powered on for a long time. The charger is still in working mode, which will consume electricity and cause resource waste, which is not conducive to energy conservation and consumption reduction.

2. Easy to cause various dangerous phenomena

Mobile phone chargers will drop the voltage from 220V to around 5V during operation, which requires them to have sufficient voltage resistance and insulation. However, with the passage of time and increasing usage, the materials on the charger will continue to age. The behavior of not unplugging the charger for a long time will accelerate the aging process of the charger, thereby increasing the possibility of short circuits and voltage breakdown in the charger. Especially for mobile phone chargers with low intelligence or substandard quality, prolonged charging time may cause the phone to overheat, leading to combustion or explosion. Excessive charging time may also increase the possibility of a short circuit at the output end of the charger. Once the output terminal of the charger is short circuited, the current at its input terminal will increase sharply, leading to the charger burning or exploding. Serious hazards can cause short circuits, accidental electric shock, fire, explosion, and injury to people.
