The mobile phone charging cable is the “lifeline” of the mobile phone, and people use it almost daily. Such a critical “lifeline” is often the easiest to ignore its “health” status. If misused, its potential safety hazards will also be released. Now, let’s discuss the hidden dangers of mobile phone charging cables.
A General List of the Potential Dangers of Mobile Phone Charging Cables:
- Do not unplug the charging circuit board after the mobile phone is fully charged;
- Avoid using the cable when the charging block/adapter has been used for too long and aged;
- Don’t attempt to charge your phone if you notice that The charger is wet;
- It is equally dangerous to charge your phone when the charger wire or adapter is damaged.

Basic Insights Into How The Mobile Phone Charger Works
The transformer in the charger reduces the high voltage of 220 volts to a low voltage of 5 volts. This process ensures a “voltage difference” between the high and low voltage.
In such a small device, if the “electric current” escapes out of the insulating layer, it could result in an explosion. Burns might also be an inevitable consequence.
As long as the charging plug is connected to the power supply, even if the other end is disconnected from the mobile phone, the primary coil of the transformer is still in working condition.
This can easily cause the charger to heat up if the insulation layer of the coil is aged or damaged, causing a short circuit.
How To Prevent Safety Hazards When Using Mobile Phone Charging Cables
To safeguard yourself and prevent safety or health hazards, you need to pay attention to the following nine points while using mobile phone charging cables
1. Do not answer the phone while charging.
Under normal circumstances, the insulation between the parts with dangerous voltage and the accessible conductive parts is broken down or the contact current is too large, which can easily cause an electric shock to the user, especially for some smartphone users. This is particularly true of low-end Chinese phones. However, a fire explosion happened to a top-of-the-line phone the person of Samsung galaxy note 7. A lot of us still remember this incident.
2. It is best to use the original charger and cable.
The original mobile phone charger has an overvoltage protection circuit and is equipped with a rectifier transformer device, which can convert high voltage into low voltage and direct current into alternating current.
Most of universal chargers are produced without protective coils, which are easy to cause the voltage or current to be too high and unstable. Excessive voltage is easy to charge the battery, and sometimes it can cause dangerous explosions, and the mobile phone can catch up flames
3. Select products with certified quality.
When buying mobile phone chargers and batteries, you must choose products that regular manufacturers qualify.
Fire experts pointed out a good charger has an overheating self-protection circuit inside. When its internal temperature reaches a certain value, it will automatically disconnect the power supply, which plays a certain degree of protection.
4. Try to charge when someone is watching.
The mobile phone battery should be charged when someone is present so that abnormal situations can be handled in time.
During charging, you should pay attention to the temperature of the charger and whether there is a burnt smell.
If the temperature is too high, it is hot to the hand, or there is a burnt smell, etc., stop charging first, check the cause, and take necessary measures before charging.
5. Do not cover up your phone while the phone is charging.
When charging, the voltage of the mobile phone is higher than the standby state. If an unqualified battery or charger is used, and the charging environment is poor, such as high temperature and humidity, accidents may occur.
6. Unplug the power plug when not in use.
After charging, remember to unplug the power plug, which can effectively prevent the power adapter from causing a fire.
7. Don’t charge For Too Long Or Overcharge
It is forbidden to charge for a long time, especially with inferior chargers and data cables, without overheating protection and an automatic power-off function. Usually don’t charge for more than four hours.
8. Choose the charger and data cable that matches the mobile phone.
Also, if you must, please avoid using your aftermarket charger and data cable indiscriminately.
9. Lastly, protect the contact points of the charging line.
This method is straightforward and reliable. Spray the contact points of your charging cables with The “nano protectant spray,” and you’re done. Its function is to significantly prolong the life of the contacts when plugging and unplugging, and there is no longer a stagnant feeling when plugging and unplugging.
