    Before talking about this matter, let’s first understand the principle of charger heating. The components of the charger that generate a lot of heat are high-voltage capacitors, switching tubes, and high-frequency transformers. These three components are quite high in temperature. It is not difficult to reduce the temperature of these three components. Generally speaking, when the output current is constant, the power of the high-frequency transformer is relatively large, and the temperature of the high-power high-frequency transformer is much lower. Simply put, it is necessary to give it extra power, just like a big car pulling small things without effort. Of course, it is easier for the switch tube to dissipate heat, as long as it is equipped with enough heat sinks. However, due to volume limitations, it is impossible to reduce heat generation. Therefore, it is inevitable that the charger will generate heat.

    Knowing the principle, we can easily understand why the charger is hot:

    • Too high temperature will accelerate the heating of the charging hair – When our mobile phone is charging, the power is lost during the conversion process, and some of the energy will be converted into heat, causing the charger plug to become hot. Although it is normal, heat will accelerate the aging of the charger.
    • Non-original genuine charger – When we use the charger to charge if the charger is not matched or is a copy product, then the charger plug is likely to become hot during the charging process, and it may even cause a short circuit.
    • Causes heat when the phone is charging – Many people like to play with their mobile phones while charging. This will cause the charger to work for a longer period, which may lead to overload operation of the charger, overheating of the charger plug, and affect the useful life of the phone.

    7 tips to solve the overheating of the charger

    1. Charge it in a cool environment – If the charger is too hot, it is best to charge it in a cool environment in summer, such as an air-conditioned house.
    2. Use the original charger – It is best to use the original charger to ensure a stable output current and protect the battery. The original charger will also generate heat, but it will not overheat and has a protective device. If your charger is overheated, it means it is fake or not original.
    3. Don’t play with the phone while it is charging – This will cause the charger to overheat if play when charging the phone, because it will work for a period of time longer than normal, which will not affect the charger and will reduce the life of the charger.
    4. Don’t overcharge – Generally, the original charger can be fully charged in about 3 hours. Do not continue charging after being fully charged, otherwise, it will cause the charger to overload and become overheated. Unplug the charger in time.
    5. Be careful of surrounding heat sources – When charging the phone, the charger should be placed away from heat sources, such as gas stoves, steamers, etc., to avoid excessively high ambient temperature, causing the charger to overheat.
    6. Reduce the number of charging – If you charge it multiple times a day, it will cause the charger to overheat, so you should control the number of charging. Generally, you can charge it once in 1-2 days, which can help extend the life of the charger.
    7. When charging, turn off the phone as much as possible – This can extend the life of the charger and protect the phone.

    There are several ways to solve the heating of the charger. It is best to use the original charger for electronic products, so be careful when the charger is heating up.

    Will the charger catch fire?

    • Theoretically won’t catch fire – Theoretically speaking, it will not cause a fire, because the charger is overloaded, if the temperature is too high during charging, the charger will automatically cut off the power, and if the charging is completed, it will also automatically turn off the power, so there will be no such thing as a fire.
    • Poor quality chargers may catch fire – However, it should be noted that if you are using a non-original inferior charger, there is a possibility of fire due to process and quality reasons, so it is suggested that you try not to use poor chargers.
    • There are hidden dangers if the charger is not unplugged for a long time – The charger uses a transformer to convert the high voltage into a low voltage. If the charger is left unplugged from the socket for a long time and it is not connected to the mobile phone, this is “no-load”, and the current also flows through the “no-load”. If the charger is not unplugged for a long time, the internal circuit board is energized for a long time, theoretically speaking, it will cause the charger to age. If the charger is of poor quality, it will easily cause a short circuit, causing fires, explosions, accidental electric shocks, and other accidents.

    It is suggested that you put the charger on the power strip, and turn off the power strip switch when not in use, to avoid the risk of short circuit, and also save the trouble and loss of plugging and unplugging the charger every time.

    How to give first aid to the charger accidentally catching fire?

    • Cut off the power first – If there is an accident and a fire occurs in the charger, the power supply must be cut off as soon as possible, and the power supply of the whole house should be cut off if necessary. Never use water to fight it out, because water is conductive.
    • Never splash water – If water is splashed on electrical appliances or chargers, there is a danger of bursting or explosion. In this case, it is suggested to use heavy clothing or bedding for swat or bedding, and call the police in time.
    • Develop good electricity habits – Fires are no small matter, sometimes bad electricity usage habits can cause fires. so you should pay more attention to electricity safety in your daily life and take precautions.

    Precautions for mobile phone charging

    • Do not charge in a cold or hot environment – When charging, try to avoid objects such as refrigerators, ovens, or places exposed to direct sunlight. If the household living conditions are in a state of frequent high temperature, it is suggested to use a high temperature resistant charging head with a built-in high-performance switching transformer.
    • Do not charge near pillows and sheets – In order to facilitate the use of mobile phones while charging, people are accustomed to charging at the head of the bed or near the pillow. If a short circuit causes spontaneous combustion, the pillow bed sheet will become a dangerous burning material.
    • Do not use a damaged charging cable – When the metal of the charging cable is exposed, leakage is likely to occur during the charging process, and the current, the human body, and the floor are likely to form a closed circuit, which poses a safety hazard. Therefore, the damaged charging equipment must be replaced in time.

    Which charger is best to buy ?

    • Original charger (safe and easy to use but expensive) – The original charger is a gift when you buy a mobile phone. It has a built-in smart chip and is safe to use. Non-original chargers may have a charging accessories design that does not meet the standards, the current and voltage cannot meet the requirements of the mobile phone, and the battery may be damaged.
    • Fast charge charger (fast charging, will reduce battery life) – Fast charging is related to the charger, USB cable, and the internal charging module of the mobile phone, all of which are indispensable. At present, the more common ones are high-pressure fast charging and low-pressure fast charging on the market. High-pressure fast charging has a large heat generation situation, while low-pressure fast charging does not have this situation, and it is more comfortable to use. To achieve the effect of fast charging, the mobile phone, USB cable, and charger must all support fast charging technology.
    • Wireless charger (easy to use, but expensive and inconvenient to carry) – The wireless charger uses wireless charging technology to transmit electric energy by using the alternating magnetic field generated between the coils. The inductive coupling technology will become a bridge connecting the charging base station and the equipment. No usb cable is needed, just place the phone directly on it to charge it.
    • Multi-port charger (It can charge multiple devices at the same time but is easy to overload and heat up) – The multi-port charger adopts intelligent shunt technology, which can be based on different models, intelligently match and stably output the required current, quickly charge without damaging the battery. It can meet the charging requirements of common devices such as mobile phones, tablets, mobile power supplies, and is easy to carry and has high practicability.
