With the popularity of smartphones, mobile phone chargers have become an indispensable part of our daily lives. However, sometimes when charging our mobile phones, we find that the charger plug is hot, which makes us worry. So, why does the mobile phone charger get hot? How to solve the overheating problem? Next, let’s explore this topic in detail.

Why does a mobile phone charger get hot?

First of all, we need to understand how the mobile phone charger works. The charger is a voltage conversion device that converts 220V AC power from household circuits into 5V DC power for use by mobile phones and other devices. During this process, due to losses in the conversion between alternating current and direct current, part of the electrical energy will be converted into heat energy, causing the charger to heat up.

In addition, the charger also needs to withstand a certain current load when charging. If the current is too large or the internal circuit design of the charger is unreasonable, it will cause the charger to overheat. At the same time, too high ambient temperature will aggravate the charger's heating.

How to solve the overheating problem?

Choose a cool environment for charging

In order to reduce the heat generated by the charger, we can choose to charge in a cool environment. Especially in summer, it is best to place the charger in an air-conditioned room or a place with a fan to help dissipate heat.

Use original charger

Using the original charger is an effective way to ensure charging safety and reduce charger heat. The original charger is highly matched to the mobile phone, the output current is stable, and it can protect the battery and charger. At the same time, the original charger usually has an overheating protection function, which can automatically cut off the power when the charger overheats to avoid safety accidents.

Avoid playing with your phone while charging

Playing with your phone while charging will cause the phone charger to be under high load for a long time, exacerbating the heating problem. Therefore, it is best to avoid using your phone while charging and let the charger get a full rest.

Don't overcharge

Generally speaking, the original mobile phone charger can fully charge the mobile phone in about 3 hours. When the phone is fully charged, the charger should be unplugged in time to avoid overcharging and overheating of the charger.

Pay attention to surrounding heat sources

When charging, be sure to keep the charger away from heat sources, such as gas stoves, steamers, etc. Prevent the charger from overheating due to high ambient temperature.

Reduce charging times

If you need to charge multiple times a day, the charger will be under high load for a long time, exacerbating the heat generation. Therefore, we should try to reduce the number of charging times, usually once a day or two.

Try to turn off your phone when charging

Turning off the mobile phone while charging can not only reduce the load on the charger and reduce heat generation, but also protect the mobile phone battery and extend the service life of the mobile phone.

It is a common phenomenon for mobile phone chargers to become hot, but as long as we pay attention to the usage method and environment, we can effectively reduce the heat of the charger and ensure charging safety. At the same time, we should also pay attention to the quality and brand of chargers, choose regular channels to purchase original chargers, and avoid safety hazards caused by using inferior chargers.
