What effect does the charger have on the socket if it is not unplugged for a long time?

When charging the mobile phone, many people have the habit of not unplugging the charger, and some even do not unplug the mobile phone charger all year round.

    So what is the impact of the charger being plugged into the socket for a long time when the phone is not charging? Let's take you to reveal the secret.

    The impact of not unplugging the charger for a long time

    1. Shorten the life of the charger

    Let the charger be plugged into the socket for a long time, due to the composition of the electronic components of the charger, there will be microcurrents passing through the socket all the time, which will cause heat generation for a long time, which is easy to cause the aging of components, and some will also cause a short circuit, which will greatly shorten the life of the charger.

    2. Power consumption

    The charger has been plugged into the socket, although it does not charge the phone, but the circuit board inside the charger is energized, so the charger is in working condition and will consume power.

    3. There are potential safety hazards

    If the charger is of poor quality, its own heat is serious, plus the environment of your own room is airtight and the weather is hot, it is easy to create an environment for the charger to spontaneously combust and self-detonate.

    Of course, because the charger is equipped with a protective device, the probability of spontaneous combustion and self-explosion of the charger is very small.

    However, the possibility of village equipment failure or copycat charger cannot be ruled out, it is best to unplug the charger or turn off the socket switch to avoid safety accidents.

    Fourth, charging is small, safety is big

    The materials and circuit boards of the regular charging head are used in accordance with national standards, and its weight will generally not change much.

    If you buy a charging head that is significantly lighter, it may be a copycat charging head. This kind of charging head is plugged into the socket for a long time and not unplugged, which will pose a safety hazard.

    Do not charge in an environment that is too cold or too hot, such as next to a refrigerator, electric oven, heater, or in direct sunlight.

    If your home is in a state of constant high temperature, and you often forget to unplug the charger, it is recommended to use a charging head with high temperature resistance and a built-in high-performance switching transformer.

    In order to facilitate the use of mobile phones when charging, we are used to charging near the head of the bed or near the pillow, it is recommended not to place the charging mobile phone near flammable pillows/sheets, if you want to charge the mobile phone overnight, it is best to stay away from the sleeping place.

    When the charger interface is loose or too tight, and some data cables are exposed metal, it is easy to leak electricity during the charging process, and it is easy to form a closed circuit with the human body and the floor, which is a potential safety hazard.

    Therefore, it is necessary to replace the data cable that has been used for a long time in time, and pay more attention to its workmanship when purchasing a data cable.
