recently
A video went viral on the Internet
The room is in shambles
The house was blackened by smoke
There are traces of burning everywhere
After the video is sent
It immediately aroused heated discussions among the majority of netizens
The person concerned also stated the cause of the fire
Everyone shared in the comments
Your habit of using the charger on a regular basis
As well as because of not unplugging the charger
An experience that almost caused a catastrophe
It's really "thrilling"
our lives
It has become more and more inseparable from electronic products such as mobile phones
Fire accidents related to the charging of mobile phones, etc
It's also more
Recently, Enshi, Hubei
A woman uses a charger to charge her mobile phone
Unexpectedly
Go upstairs to dry your clothes and come back
It was found that the phone charging cable had spontaneously combusted
Of course, looking at these cases
Many friends may still be confused
Is it possible that the charger will have power even if the phone is not connected?
The answer is: Yes, of course
Let's take a look
A set of experiments done by the School of Physics of Peking University
Testing a non-working charger with a current probe showed a current reading.
When connected to the mobile phone, the current reading changes significantly.
From the experiment, it is found that as long as the charger is connected to the circuit board, even if there is no load, it will generate a certain current, some of which are small and some are large. This is because the charger is a transformer and rectified device, and it is always in working condition after it is plugged into the circuit board.
On the other hand, the charger is a device that turns high-voltage electricity into low-voltage direct current, if the charger is placed on the plug-in board for a long time, it will continue to heat, thereby accelerating the aging of devices and materials, and is prone to short circuit or high-voltage breakdown, thereby causing fire hazards.
therefore
If the charger
Put it on the power strip for a long time and do not pull it out
The following problems will inevitably arise
Security is at stake!
If the charger is powered on for a long time and is not unplugged from the socket, the wiring will deteriorate and heat up, and the insulation layer of the coil will be melted. In the long run, it may cause a short circuit, and in severe cases, it will lead to electric shock, explosion, fire and other accidents.
Wallet challenged!
The charger is a transformer and ballast device, which will always be in working condition as long as it is connected to power. As long as the charger is not unplugged, there will always be current passing through this coil, which will undoubtedly consume electricity, although the power consumption is not much, but it will add up to a lot of waste.
Do not unplug the charger for a long time, etc
It is very easy to cause safety accidents
Don't leave anything to chance
Don't do it for the sake of saving trouble
And the root of the bane
When charging your phone
