When the mobile phone charger is not charged, I suggest that it is better to pull it out, for the quality of the unqualified charger or when the grid voltage is not normal, it is easy to burn the charging head.
Better charging head in the factory have been debugging set, in the mobile phone charging, the initial charging current is larger, when the fast full charge, because the battery voltage in the mobile phone is getting higher and higher, then the charging head intelligent control charging speed, charging more and more slowly, called a trickle, metaphorical charging current like a trickle, relatively small and fine, The advantage of such charging is to protect the phone from accidents caused by excessive battery voltage.
Although the better charging head has a perfect protection function, we should remember to pull out the charging head when we are finished charging. This is because: first, the charging head is plugged into the power supply for a long time, and the internal circuit of the charging head is always powered on, which will consume a certain current, and in the long run, it accelerates the aging of the components. Second, the charging head is plugged into the power supply for a long time, and it is easy to burn the charging head when the power grid voltage is unstable.
In summary, it is better to pull out the charger when fully charging the phone, if it is plugged into the power supply for a long time, there will be the possibility of burning out, or pay attention to the point is better.
Well, today's answer to this, I hope my answer can help you, more electrical knowledge, please pay attention to Lanxiang electrical, thank you.
The phone charger is plugged in when it is not charged. It will be fine. This is because the phone charger and the data line are just a single line, if the phone is not connected, it will not form a loop, that is, there is no current through, and it has no effect on the charger. Charging recommendations, if the charger overheats, it is recommended to stop charging, so that the charger life will be better.
There is a power socket on the market, the socket has a mobile phone charger, this socket can plug in 220V mains power supply TV, desk lamp and other electrical appliances, but also can replace the mobile phone charger.
This shows that there is no need to unplug the phone charger when it does not charge the phone.
TV, desk lamp, when not in use, there is a manual mechanical switch, turn off the switch, there is no need to pull the power plug of the TV, desk lamp from the power socket.
The principle of mobile phone charger is to switch the power supply, when the mobile phone battery is lost, the mobile phone is plugged in to automatically start charging, and it is automatically closed after being fully charged.
The mobile phone charger is a switching power supply, which is automatically opened and closed, replacing the manual mechanical switch. It's as simple as that.
Our current smart phones and tablets are used lithium batteries, this battery energy density, small size, can be made into various shapes, and no memory effect, can be used with the rush, without worrying about the reduction of battery capacity, of course, with the extension of the use of time, the capacity will become less, but this is not a memory effect.
Nowadays, smart phones have more and more functions, larger and larger screens, stronger and stronger performance, and more and more consumption of battery power, but there has been no qualitative breakthrough in battery technology in the last year. As a result, smartphones now need to be charged almost every day. Many people plug in the charger before going to bed and don't unplug it until the next day.
This approach looks more dangerous, but in fact, it is not, in the mobile phone, in order to protect the battery will not overcharge or overdischarge will have the corresponding power management chip, to distribute, can reach the battery power, when the battery voltage reaches the corresponding standard, the power management chip will automatically cut off the charging current to protect the battery. So after the battery is fully charged, it is no longer charged, even if the charger is still plugged into the phone.
But the key to the problem is that the charger does not pull the current through, if the quality of the component is not up to standard, it may cause fire, there is a risk.
No need to unplug the charger. Unless the quality is not up to standard, there will be no problems.
The current charger design is more intelligent, will change the charging current according to the size of the charge, fast charging appliances can change the size of the current and voltage, and the protection of the line is also very good, there are anti-overcharge, short circuit, anti-reverse, anti-overcurrent, etc., so even if the charger is plugged into the socket for a long time, there will be no accident. And in real life, there are many people who have not unplugged their mobile phones after charging, and have developed a habit, feeling that it is too troublesome to unplug every day, although in theory there is no problem, but we still have to develop a good habit of often unplugging. Afraid of power grid instability caused by voltage and current instability, resulting in damage to the charger, the general charger even if damaged will not affect the output, that is, can not be charged, but afraid of internal short circuit caused by fire, which is more dangerous, it is recommended to unplug the charger or turn off the socket switch. It's safer.
If it is a regular charger, there are intelligent control circuits, when there is no load, it will automatically break, under normal circumstances is fine, of course, those cheap copycat goods that is a different matter
It's okay. I've been fine all year,
It's not a problem. My computer room uses a charging head to charge LED lights, small speakers, and there are charging bars and two charging heads under the TV, which are generally plugged in there all day.
