The “potato” of the charger, also known as a transformer or power supply, converts the alternating current from the socket, which is 220 volts or 110 volts, depending on the region, into direct current worth 5 volts, an adequate amount for the cell phone. .

During the conversion process, part of the electrical energy turns into heat, which heats the device. For this reason, when you unplug the charger, it may feel hotter.

This energy conversion generates losses, and heat dissipation is a natural consequence of this process. Therefore, it is normal to feel the charger heating when touching it.

However, it is essential to remember that excessive overheating may indicate problems with the charger or cell phone, requiring attention to avoid damage.

Essential tips when charging your cell phone

While feeling a little heat from this transformer is normal, it is crucial to monitor and ensure that it does not exceed safety limits.

A very useful tip is to see if you can hold the charger in your hands right after unplugging it from the socket.

However, if you can’t, you need to change your charger as quickly as possible before something happens that could harm your battery. security.

To avoid overheating the charger, it is also useful to leave it in a cool place. This allows heat generated during charging to be dissipated more efficiently.

When kept in closed spaces, which prevent heat from escaping, it tends to accumulate and may result in the charger overheating.
