Can the charger stay unplugged? Will the charger drain power if it is not unplugged?

Hello, the charger should be unplugged in time after charging, the charger can not be unplugged all the time, the charger will be easily damaged if it has not been unplugged, and the charger will waste electricity if it has not been unplugged.

As long as it is not connected to the mobile phone, it will be in a non-charging state, and there will be no power loss. But the best thing to do is to unplug it after the charging is completed, which is a more correct approach.

Of course, the charger can be unplugged all the time, but there are certain safety hazards in this way, so after using the charger, the charger should be quickly unplugged or turned off.

The charger cannot be unplugged all the time, because in the process of charging, this telecom is also electrified, so it is best to unplug it.

No, because the charger is composed of electronic components, if the charger is plugged into the socket for a long time, it is easy to cause heating, cause aging of components, and even short circuit, which greatly shortens the service life of the charger.

Can the charger stay unplugged? I think it's better to unplug the charger when you run out of chargers. It's safer to unplug the charger. The next time you charge it, plug the charger back in again.

The charger has not been pulled, which is easy to shorten the life of the charger, which can easily cause heating and cause aging of components, and also consume electric energy, which has potential safety hazards. Some chargers with a low degree of intelligence may also make the phone dangerous.

Of course, this is okay, as long as you are not afraid of consuming electricity, but an inferior charger may catch fire.

You mean put the charger on the plug and don't pull it out, right? Under normal circumstances, there is no problem, but if there are no children at home, it is recommended to unplug it, because children like to play with the plug, if you accidentally lick the charging port, it is likely to cause the charger to connect, and then short circuit.

Yes, when the charger is not charging, it will consume the same power on the socket. From a physical point of view, the charger has a voltage conversion effect; A transformer is used to convert high voltage into low voltage, which is then fed to electrical appliances. The transformer principle of the charger is magnetic field induction, and there are two parallel coils inside; One of the coils is connected to the power supply, which creates a magnetic field when an electric current passes through it, which in turn produces direct current of different voltages.

So, as long as you don't unplug the charger, there will be a coil that is working all the time, thus consuming power. In general, one side is not unplugged on the socket; Chargers that are not connected to electrical appliances on one side are in a "no-load" state, and the charger will consume power because there is also current passing through when there is no load.

Charge the charger with attention

1. Use the original charger: the current is unstable in the non-original charger, and the inferior power bank or charger is also easy to cause the battery to overheat and cause danger.

2. Pay attention to the damage of the charger: Before charging, it is best to check whether the data cable of the charger, including the charging head, is in good condition, and once the shell is found to be damaged and the metal is exposed, it should be replaced in time.

3. Pay attention to power consumption: the mobile phone battery is a new type of lithium battery polymer, the battery can not be used to the extreme state and then charged, when the power is less than 20%, a red alarm will be issued to prompt charging, and in the case of non-essentials, the charger can be unplugged when the power is charged to 80%, do not wait for the battery to be fully charged and continue to charge, and do not charge it all night.

After charging the mobile phone, it is the habit of many people to take the mobile phone off and play it directly. But this little habit is actually very dangerous!

Hazard one

Power consumption

When the charger is still connected to the power strip when it is not charging, the circuit board inside the charger is powered on, that is, it is still in working condition, even though the charger is not connected to the mobile phone or electrical appliance at this time.

It will definitely consume some power in working condition. Because even if the charger is not connected to the phone, its control circuit is working, and there will still be current, albeit in small amounts.

According to reports, the largest power consumption of mobile phone chargers is 308 milliwatts. According to calculations, 100 milliwatts of electricity consumption is insignificant for an individual, but if families with mobile phones do not pay attention to it, the conclusion is very striking.

According to a survey in 2012, the total number of mobile phone users of the three major operators has approached 1 billion, assuming that 1 8 people do not pull out the charger, then there are 100 million chargers plugged into the plug-in board every day, wasting electricity in most of the day, according to the power consumption of 100 milliwatts per charger, its total power is about 10,000 kilowatts, equivalent to more than 6,000 household air conditioners running at the same time.

Hazard two

Fire hazards

Not only that, due to the prevalence of chargers for various small electrical appliances, the number of chargers for various mobile phones, digital cameras, laptops, video cameras, etc., is also uneven.

When the electrical appliance is unplugged from the charger, the charger is in an interrupted state, but some chargers will still be on after the electrical appliance is unplugged, which will cause a current loop within a certain range, therefore, not only the state will cause unnecessary power consumption, but also there is a great safety hazard.

Therefore, be sure to plug the charger into a ventilated one that is easy to dissipate heat'Place charging, and at the same time master the use time of the charger, do not "continuous combat", let alone keep the charger plugged in the socket. When people leave the room for a long time, they should unplug the charger to avoid causing disasters.

Hazard three

Radiation damage

So, will the radiation from the empty state of the charger be harmful to the human body?

During the period of frequent electricity consumption of mobile phone charging sockets, the magnetic induction intensity within 30 cm around it will reach 1400 milligauss, and the number of immune function cells in the human body may be reduced, which will cause certain damage to human health.

Therefore, the human body should be kept away from the mobile phone charging socket 30 cm away, especially do not put the mobile phone charger next to the bed when it is in working condition.

No. The charger can not be plugged in the power supply all the time, the harm of the charger being plugged in the power supply all the time is great, and the materials on the charger will continue to age with the passage of time and the increase in the number of uses. The act of not unplugging the charger for a long time will accelerate the aging process of the charger, which will increase the possibility of short circuits and voltage breakdowns of the charger.

When most people use the charger, many people will keep the charger plugged in the power supply and do not unplug it when they are not in use, which will cause some harm, and it is not okay to do so. It is recommended that you unplug the charger from the power supply when you are not using it. With the passage of time and the increase in the number of uses, the materials on the charger will continue to deteriorate.

The act of not unplugging the charger for a long time will accelerate the aging process of the charger, which will increase the possibility of short circuits and voltage breakdowns of the charger. Once the output of the charger is short-circuited, the current at its input will increase dramatically, which will cause the charger to burn or**.

The hazards of not unplugging the charger for a long time are as follows:

1. Shorten the life of the charger.

Since the charger is composed of electronic components, it is easy to cause heat generation if the charger is plugged into the socket for a long time.

It causes the original to age, and even a short circuit occurs, which greatly shortens the service life of the charger.

2. Power consumption.

After charging, the charger has been plugged into the socket, although the phone is not charged, but the circuit board inside the charger is still in a normal working state, which will consume power. Research data shows that the original charger of an iPhone has not been unplugged, and it consumes about one kilowatt-hour of electricity per year.

3. There are potential safety hazards.

For some mobile phone chargers with a low degree of intelligence or substandard quality, charging time too long may overheat the phone, which in turn will cause the phone to burn or **. At the same time, charging times that take too long may also increase the likelihood of a short circuit at the output of the charger. Once the output of the charger is short-circuited, the current at its input will increase dramatically, which will cause the charger to burn or**.

Extended Materials. Be sure to remember to unplug the charger after charging, and do the following three things for your own safety:

1. Do not charge in an excessively cold or overheated environment.

2. Do not charge near pillows and sheets.

3. Do not use the charging cable that has been damaged.

Lots of power strips.

There is a switch on each socket. When charging your phone, it's best to connect the charger to this kind of switched power strip; After charging, you can directly turn off the corresponding switch on the power strip without unplugging the charger, which is not only simple and convenient, but also very safe.

Yes. Because the charger does not set a power switch, the internal circuit is powered on all the time, and there is a no-load loss. It's just that now technology makes no-load losses very small.

The charger will also consume power when it is no-load standby, but the energy consumption is very low, and the general regular charger will not have potential safety hazards, the charger is designed to work uninterrupted for a long time, such as routers, surveillance cameras, etc., these adapters work all year round, and there is no problem! Of course, it is recommended to turn off the power if it is not used often, and if you don't like to plug and unplug frequently, you can choose a plug strip or wall socket with a switch!
