Will the charger hot will explode? What is the cause of a hot charger?

Definition of charger
Charger is the use of high-frequency power technology, the use of advanced intelligent dynamic adjustment charging technology. The industrial frequency machine is designed with the traditional analog circuit principle, the machine internal power devices (such as transformers, inductors, capacitors, etc.) are relatively large, there is generally less noise when running with a larger load, but the model is more resistant to the harsh grid environmental conditions, reliability and stability are stronger than the high frequency machine.

The normal working conditions of the charger

(1) The altitude does not exceed 2000 meters;
(2) The temperature of the surrounding medium is not higher than +40℃ and not lower than -10℃; (3) The relative humidity of the air is not more than 85% (when the medium temperature is 20℃±5℃)
(4) no place with conductive dust;
(5) No explosive hazard environment;
(6) Environment that does not contain gases and vapors that can corrode metals and insulation;
(7) In places where there is no rain or snow intrusion;
(8) in the vertical plane inclination of not more than 5 degrees and no violent vibration and impact of the place.

What is the cause of the charger hot?

When charging cell phones, it is normal for the charger to get hot, there are losses in the conversion of AC and DC power, the general charger uses a high efficiency switching power supply, but is limited by the size, so there is basically no PFC circuit, so the power factor is less than 0.7, the rest of the energy is basically converted into heat.
It is normal for the charger to be a little hot when charging, so as long as there is no odor, do not worry about it, but it is best to put it in a ventilated place, because the heat will accelerate the aging of electronic components.

Will the charger explode if it is hot?

The normal charger will never explode, but some quality problems with the substandard products may explode depending on the situation. Now the basic cell phones used are lithium batteries, the probability of finding the danger is one in 100 million to three in 100 million. Although the probability of an accident is extremely small, but 80% of accidents occur when charging. This is because, when charging the phone voltage is higher than when standby, if other operations such as calls are carried out at the same time, the voltage will exceed the usual many times, so that the use of poor quality chargers, cell phone electronic components aging or moisture, etc. may cause leakage, connected to the mains in the socket, and then the current through the human body, once a short period of time through the human body, the current is too large, it may lead to death.

Solutions to prevent the charger from overheating

1, placed in a cool environment charging.
If the phone charger overheating, it is best to put in a cool environment in the summer to charge, such as air-conditioned house. This way the phone charger will not overheat.

2. Use the original charger.
When charging the phone, you should use the original charger, which can ensure a stable output current, and the role of battery protection. The original charger will also be hot, but will not overheat, there are protection devices. If your charger is overheating, it means it is counterfeit or not the original one.

3, do not play with the phone when the phone is charging.
When charging the phone also play with the phone, it will cause the phone charger overheating, because to work more than normal for a while, so the charger will not, will reduce the life of the charger.

4, do not overcharge.
General cell phone charging original charger for about 3 hours can be fully charged, full do not continue charging, otherwise it will lead to overload the charger, become overheated. To unplug the charger in a timely manner.

5, careful of the surrounding heat sources.
When charging the phone, the charger should be placed away from heat sources, such as gas stoves, steamers, etc., so as not to overheat the charger due to high ambient temperatures.

6、Reduce the number of charging.
If the charger is charged many times a day, it will cause the charger to overheat, so you should control the number of times you charge it, usually once or twice a day, which can help extend the life of the charger.

7, when charging, the phone as far as possible to turn off.
This can extend the life of the charger, but also to protect the phone.
