Many smartphone users are concerned that their charger gets hot and fast when charging.
This is what causes the charger to heat up.
This can be seen above all when using the fast charging function.
However, other things can also cause the charger to heat up.
No certified charger designed for a specific model of the smartphone should become very hot.
What could be the impact of overheating the charger?
Continuous overheating will cause problems with the miniature circuit board inside the charger body.
After some time, the machine is sure to fail.
Damage to the board can cause a short circuit, and the high currents will cause a fire.
It will not cause a large-scale fire, but the case will surely melt.
What causes the charger to heat up?
Several reasons cause the gear to heat up.
They can be both natural and a consequence of a malfunction of the charger itself.
The efficiency of any charger is less than 100%.
During voltage transformation, there will be a loss of energy, accompanied by the release of heat.
Many smartphones have a fast charging feature.
This is typical for Chinese-made chargers.
The same situation can be observed when a heavier load is connected to the working charger.
This will lead to overheating of the gear, from which it can burn out.
In this case, the battery will not charge at all.
By this sign, it is not difficult to identify the problem.
