CAUTION: Cell phone charger gets too hot? Understand why

The heat generated is a natural effect of the process of transforming the energy from the socket into a form compatible with the cell phone. This warming, however, must be “totally bearable”. So when is there reason to worry?

If the charger becomes excessively hot, to the point that you can’t touch it or it starts to smell burning, this could indicate a problem. In this case, investigation is necessary.

A very hot charger could be a sign of a defect in the equipment itself or in some part of the cell phone, such as a capacitor, resistor or chip in short circuit.

Such faults can trigger excessive electrical current when connecting the charger to the mains, which can result in overheating, fire or even explosion.

Despite the possibility of fire and explosion, experts emphasize that the charger, in itself, is not deadly. However, it is important to highlight that it is capable of causing injuries. Therefore, caution is necessary.

Essential care

  • Charge the battery in an appropriate location, away from the sun and hot surfaces, in order to avoid the device overheating;
  • Do not handle the charger with wet hands and avoid recharging in humid environments, such as the bathroom. Moisture can cause the pins to short circuit, which will damage the device or charger;
  • Make sure you fit the charger perfectly into the port on the cell phone and align the pins to avoid the risk of short circuits.
