Many people check their mobile phones first thing in the morning, and check their mobile phones for a while before going to bed at night. In order to keep the battery life of the mobile phone uninterrupted, many people are used to charging the mobile phone before going to bed. But you know what? It's dangerous to charge like this, let's see together.
24 hours standby mobile phone charger
On weekdays, many people will keep the mobile phone charger plugged into the power supply without unplugging it, which is convenient. In fact, this is a hidden danger.
On May 17, 2018, in Xinxiang, Henan, black smoke was coming from the second floor of a resident's house and was promptly discovered by community staff, who brought a fire extinguisher to put out the fire. After the smoke dissipated, the staff found that the bed and bedding in the house had been burned. Fortunately, no one was in the house when the fire started, and the fire was put out in time, so no further damage was caused.
Later, according to the preliminary analysis of the scene, the cause of the fire was that the mobile phone that had been charged for a long time was not pulled out of the socket, and the charger was ignited.
Lei Yian, an associate professor at the School of Physics at Peking University, introduced that the charger is a voltage-transforming and rectifying device. It is powered on when plugged into the circuit board, consumes a certain amount of current, and is always in working condition.
If the charger is left on the power strip for a long time, it will continue to heat up, which will accelerate the aging of devices and materials, which is prone to short-circuit or high-voltage breakdown, resulting in a fire hazard.

Beware of explosions
The usage rate of mobile phones is too high, 90%, 70%, 30%, 5%...
Modern people have a common anxiety - the mobile phone is out of power.
Many people are accustomed to charging their mobile phones for a long time and charging them overnight before going to bed. Is this really safe? Not so.
In November 2017, Hunan, a family of four suffered a fire, and they were asleep before they could react. The two most seriously injured children were ultimately unable to save their lives. The cause of the fire may be caused by two mobile phones being charged and heated under the pillow.
In fact, under normal circumstances, the phone can be fully charged after three or four hours of charging. It is recommended to unplug the power cord after charging.
Do not charge the mobile phone overnight, try not to put the mobile phone on the bedside to charge, to prevent danger and cause personal injury.
In addition, try not to make phone calls for a long time while charging. Because, when charging, the battery of the mobile phone will generate heat. If you continue to make calls for a long time, the heat will increase rapidly, which is easy to cause danger.
Every summer, the number of patients injured by the explosion of mobile phone charging and power bank will increase significantly. remind here
Charger or similar appliance catches fire, how to first aid
The power supply should be cut off at the first time, and the power supply of the whole layer can be cut off if necessary.
Do not use water to fight! Because water is conductive, and if it is splashed on chargers or other electrical appliances, it is easy to burst or explode.
When the flame is small, you can use heavy clothing or bedding to beat or cover the flame to isolate the air. If necessary, call 119 in time to call the police.
