Connecting the mobile to the charger and noticing that this is heated is a usual experience for most users. Although a certain level of heat during loading can be considered normal, it is not always an harmless. Understanding what is behind this warming and knowing how to prevent it is key to prolong the shelf life of our devices and avoid possible accidents.
When a charger is connected to the current, an energy conversion process begins: the alternating current that comes from the plug is transformed into direct current, which used electronic devices. During this process, part of the energy inevitably dissipates in the form of heat due to the resistance of the internal components. This phenomenon is known as Joule effect.
The greater the resistance and worse the quality of the materials, the more heat it will be generated. Therefore, the Low quality or non -approved loaders tend to heat up more easilysince its components do not manage energy efficiently.
Factors that intensify overheating
Beyond internal functioning, there are other elements that can aggravate this warming:
- Inappropriate use: Connect a loader designed for a low energy demand device to one that consumes more power than it can supply will cause overwhelming that generates additional heat.
- Hot environments: High external temperatures or load the mobile on surfaces that retain heat (such as sofas, beds or cushions) hinder the correct ventilation of the charger.
- Intensive use during load: Use the mobile for demanding tasks while loading (such as games or videos) increases both the device temperature and the charger.
A hot charger does not always represent a threatbut if the temperature exceeds certain limits, it can lead to consequences. Among the most common are the premature deterioration of the charger and the device, operating failures or, in extreme cases, fire risk.
Therefore, notice that the charger is too hot in touch or perceive a strange smell should be interpreted as a Alert sign.
How to prevent and act
- Choose certified loaders: Always prioritizes the use of original loaders or recognized brands that have European security certificates.
- Make sure compatibility: Verify that the charger has the appropriate capacity for the device. A loader with less power of the necessary will work forced and will reheat.
- Check the status of cables: A damaged cable can become a critical point of overheating or short circuit. Replacing it in time is fundamental.
- Load in ventilated places: Ensures good ventilation of the charger and avoid covering or placing it on surfaces that catch heat.
- Do not expose the direct sun charger: Especially in summer, environmental heat can be a determining factor in the thermal problems of the devices.
- Interrupt the load if something is not going: If you detect excessive heating, immediately disconnect the charger and let it cool before using it again. Do not ignore signs such as deformations, burns or unusual noise.
