The charger uses high-frequency power technology and uses advanced intelligent dynamic adjustment charging technology. The power frequency machine is designed based on the traditional analog circuit principle. The internal power components of the machine (such as transformers, inductors, capacitors, etc.) are relatively large. Generally, there is less noise when the load is larger, but the model is bad. The power grid environmental conditions have strong resistance, and the reliability and stability are stronger than those of high frequency machines.
(1) The altitude does not exceed 2000 meters;
(2) The temperature of the surrounding medium is not higher than +40 ° C and not lower than -10 ° C; (3) the relative humidity of air is not more than 85% (when the medium temperature is 20 ° C ± 5 ° C);
(4) Where there is no conductive dust;
(5) An environment free from explosion hazards;
(6) It does not contain an environment capable of corroding metals and insulating gases and vapors;
(7) Where there is no rain or snow;
(8) Where the vertical plane is inclined no more than 5 degrees and there is no severe vibration and impact.
When the mobile phone is charging, the charger is normal. The AC and DC power is lost during the conversion. The general charger uses a high-efficiency switching power supply, but it is limited by the volume, 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. As long as there is no smell, do not care about it, but it is best to put it in a ventilated place, because heat will accelerate the aging of electronic components.
A normal charger will never explode, but some defective products with quality problems may explode as appropriate. The basics used in mobile phones today are all lithium batteries, and the probability of finding danger is between one million and three hundred million. Although the probability of an accident is extremely small, 80% of accidents occur when charging. This is because when the mobile phone is charged with a voltage higher than standby, if other operations such as talking are performed at the same time, the voltage will be many times higher than usual. In this case, the use of inferior chargers, mobile electronic components, aging or moisture, etc. may cause leakage, and the socket The internal power supply is connected, and then the current passes through the human body. Once the current through the human body is too large, it may cause death.
1. Charge in a cool environment.
If the phone charger is overheated, it is best to charge it in a cool environment in the summer, such as an air-conditioned room. This way the phone charger will not overheat.
2. Use the original charger.
When charging the phone, the original charger should be used, which ensures stable output current and protects the battery. The original charger will also heat up, but will not overheat and have protective devices. If your charger is overheated, it means fake or shoddy, or not original.
3. Do not play the phone while the phone is charging.
When the mobile phone is charging, playing the mobile phone will cause the mobile phone charger to overheat, because it will work for a longer period of time than normal, so that the charger will not, it will reduce the life of the charger.
4. Do not overcharge.
Generally, the original charger for mobile phone charging can be fully charged in about 3 hours. Do not continue charging after it is full. Otherwise, the charger will be overloaded and become overheated. Unplug the charger in time.
5. Be careful of the surrounding heat source.
When charging the mobile phone, the charger should be placed away from heat sources, such as gas stoves, steamers, etc., to avoid excessive ambient temperature, causing the charger to overheat.
6. Reduce the number of times of charging.
If you charge more than one day, it will cause the charger to overheat, so you should control the number of times of charging, usually one or two days to charge, can help extend the life of the charger.
7. When charging, the phone should be turned off as much as possible.
This will extend the life of the charger and protect the phone.
