Reasons why the charger plug is hot

When charging a mobile phone, it is normal for the charger to generate heat. There is loss in the conversion of AC and DC. Generally, chargers use higher-efficiency switching power supplies. However, they are limited in 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 energy.

It is normal for the charger to be a little hot when charging. As long as there is no peculiar smell, you don't need to worry about it. However, it is best to place it in a ventilated place, because heat will accelerate the aging of electronic components.

The following describes the solution to the charger overheating:

1. Charge in a cool environment.

If the mobile phone charger overheats, it is best to charge it in a cool environment in summer, such as an air-conditioned room. This way the phone charger won't overheat.

2. Use the original charger.

When charging your mobile phone, you should use the original charger, which can ensure 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 overheating, it's either fake or not original.

3. Do not play with your phone while it is charging.

Playing with the phone while the phone is charging will cause the phone charger to overheat, because it will work for a longer period of time than normal, which will not damage the charger and reduce the life of the charger.

4. Don’t overcharge.

Generally, the original mobile phone charger can be fully charged in about 3 hours. Do not continue charging after it is fully charged, otherwise the charger will be overloaded and overheated. Unplug the charger promptly.

5. Be careful of surrounding heat sources.

When charging a mobile phone, the charger should be placed away from heat sources, such as gas stoves, steamers, etc., to prevent the ambient temperature from being too high and causing the charger to overheat.

6. Reduce the number of charging times.

If you charge it multiple times a day, it will cause the charger to overheat, so you should control the number of charging times. Generally, it is enough to charge it once a day or two, which can help extend the life of the charger.

7. When charging, try to turn off the phone.

This can not only extend the life of the charger, but also protect the mobile phone.
