What will happen if charger charge for a long time?

In order to save trouble, many people rarely unplug the charger plugged into the bed. Is there any harm in not unplugging the charger for a long time? The answer is yes, there will be the following adverse effects.

Shorten the service life

The charger is composed of electronic components. If the charger is plugged into the socket for a long time, it is easy to cause heat, cause aging of the components, and even short-circuit, which greatly shortens the service life of the charger.

More power consumption

The charger has been plugged into the socket. Although the mobile phone is not charged, the circuit board inside the charger is still energized. The charger is in normal working condition and consumes power.

Research data shows that if the original charger of a mobile phone is not unplugged, it consumes about 1.5 kWh of electricity every year. The cumulative power consumption of hundreds of millions of chargers around the world will be very huge. I hope that we will start from ourselves and save energy every day, which is not a small contribution.

Notes on charging

Do not charge in a too cold or too hot environment.

Try to avoid objects such as refrigerators, ovens, or places exposed to direct sunlight when charging.

If the living conditions are in a state of frequent high temperature, it is recommended to use a high temperature charger with a built-in high-performance switching transformer.

Do not charge near pillows and sheets

In order to facilitate the use of mobile phones while charging, people are accustomed to charging at the head of the bed or near the pillow. If a short circuit causes spontaneous combustion, the pillow bed sheet will become a dangerous burning material.

Do not use damaged charging cables

When the metal of the charging cable is exposed, leakage is likely to occur during the charging process. The current, the human body, and the floor are likely to form a closed circuit, which poses a safety hazard. Therefore, the damaged charging cable and equipment must be replaced in time.
