1. It is normal for the fast charger to heat up.
2. Inside the charger, when the electronic components are overcharged, a part of the electrical energy will be converted into heat energy.
3. This is normal.
4. Calorific value is related to voltage, current and resistance.
5. If the output voltage and current of the charger are large, more heat will be generated, and the charging time will be shortened.
6. So it is normal for the charger itself to heat up.
This is a normal phenomenon. The amount of heat is related to voltage, current and resistance. If the voltage and current output of the charger is relatively large, the relatively hot point, and the charging time will be shortened. So it is normal for the charger itself to heat up.
The heat of the charger is normal, as long as it is not particularly hot, it will not affect the use. If the fever is abnormal can find after-sales treatment!
