Precautions for Using Mobile Phone Charger

Oct 06-2021

1. The hazard of the PD phone charger being plugged in the socket all the time


(1) Power consumption


The PD phone charger has been plugged into the socket. Although the mobile phone is not charged, the internal circuit board of the charger is energized, so the charger is in working condition and consumes power.


(2) Shorten the life of the charger


If the charger is plugged into the socket for a long time, since the charger is composed of electronic components, a small current will flow when it is plugged into the socket for a long time. Greatly shorten the life of the charger.


(3) There are potential safety hazards


The charger has been plugged into the socket. If the charger is of inferior quality, self-heating is serious, and your own room environment is closed and the summer weather is hot, it is easy to create an environment for the charger to spontaneously ignite and explode.


2. Precautions for charging with PD phone charger


(1) Don't make calls while charging


In the charging state, the insulation between parts with dangerous voltage and accessible conductive parts is broken down or the contact current is too large, which can easily cause electric shock to the user. Making and making calls when the mobile phone is in close contact with the fast charger is already commonplace for friends, and you should be more careful. In addition, inferior chargers can easily catch fire.


The original mobile phone chargers are like a small power supply bureau, which has overvoltage protection circuits and transformer devices, which can convert high voltage to low voltage, and convert alternating current to direct current. It is not produced by the original manufacturer, and may not have a protective coil, which may cause the voltage or current to be too high and unstable. Excessive voltage can easily bulge the battery and sometimes cause a dangerous explosion.


(2) Qualified quality is the key


When buying a PD phone charger, you must choose a qualified product from a regular manufacturer, and don't try to buy an unqualified product from an unqualified manufacturer. Products produced by non-regular manufacturers may not have protective coils, which can easily make the voltage or current excessively high and unstable. Excessive voltage can easily bulge the battery and sometimes cause a dangerous explosion.


(3) Pay attention to ventilation and heat dissipation


When charging, the phone voltage is higher than the standby state. If you use an unqualified battery or charger, and the charging environment is poor, such as high temperature, humidity, etc., accidents may occur, so please charge your friends in a well-ventilated place .


(4) Try to be supervised when using


The mobile phone should be charged when someone is there as much as possible, so that abnormal situations can be dealt with in time. Pay attention to the temperature of the PD phone charger and whether there is a burnt smell during charging. If the temperature is too high, there is obvious hot or burnt smell, etc., stop charging first, check the cause and perform necessary treatment before charging.


(5) Pull out the plug after completion


After charging, remember to unplug the charger, which can effectively prevent the power bus from causing a fire.
