Many people often have the bad habit of not unplugging the charger when using the mobile phone charger. Why is this a bad habit? It is because there are many hazards, such as fire, if they do not unplug the charger after charging for a long time.
If the charger is not unplugged, it will cause fire. If the charger does not unplug for a long time, the charger uses a transformer to convert high voltage into low voltage. If the charger does not unplug on the socket for a long time and it is not connected to the mobile phone, it is in 'no-load', and there is also current in 'no-load'. If the charger is not unplugged for a long time, the internal circuit board is powered on for a long time, which will theoretically lead to the aging of the charger. If the quality of the charger is not good, it is easy to cause short circuit, fire, explosion, accidental electric shock and other accidents. It is worth mentioning that many mobile phone users go to work without pulling out the plug after charging. Either there is no one at home or there are only the elderly and children at home, which aggravates the possibility of unsafe factors and brings harm to their families.
Experts remind consumers that the general mobile phone can be charged for up to 4 hours, and the charger should be unplugged after charging. For convenience, you can also buy a safety socket with a power switch. When you don't use electrical appliances, you can press the switch on the safety socket to disconnect the power supply.
