Mobile phone charges be dangerous goods? Why does mobile power source love explosion

Not long ago, the Guangzhou Metro included mobile power supply for mobile phone charging in the category of dangerous goods. The subway broadcast was broadcast on a circular basis and passengers were constantly reminded not to use mobile power to charge on the subway. Prior to this, the dangerous goods specified by the Guangzhou Metro included flammable and explosive items such as gasoline, kerosene, and water.

Since when, the mobile power supply and flammable and explosive dangerous goods on the equal sign! You know, at all the entrances and exits of the subway station, there are more or less a few small vendors selling mobile phone charging treasures. This makes people think about it. They are afraid of the mobile power in their bags and pockets. It's a random bomb?

Why does the mobile power supply spontaneously ignite and explode?

Fire fires and explosions often occur on low-priced, low-quality mobile power supplies, because the profiteers who manufacture these inferior products have tampered with electric cores, circuits and wires in order to make huge profits. These pose a great threat to our personal and property security.

Horrible shoddy power core.

The core of the mobile power supply is the core of the electric core. At present, there are two main types of electric cores that can be used for mobile power supply. One is a cylindrical design with a "18650" electric core with a diameter of 18 mm and a height of 65 mm. The other is a polymer material. Core, It is very similar to cell phone batteries and is generally shaped like a square. The chemical properties of this battery are relatively stable and safer.

Comparing the two types of core materials, about 60 % of the mobile power sources on the market currently use 18650 cores. Both products are theoretically safe.

Of course, the 18650 battery itself is not resistant to overcharge, the probability of the flip product fire, explosion is there, before the cottage millet mobile power explosion incident can explain the problem. In particular, the quality of the mobile power supply is even more insecure when the profiteer has tampered with it.

The use of low-quality power core manufacturing mobile power supply, in addition to resulting in less power, fast loss, there are also safety performance problems, there will be explosions. In particular, when a large capacity of mobile power is exploded, the consequences are very serious. Therefore, when choosing mobile power supply, you must choose a product with a strong core.

Low quality wire easily short circuit

When I was a child, I bought a lot of earphones for a dollar or two. The wire of these earphones was peeling in a few days. The same is true of the short line of the mobile power supply. The inferior wire is easily deformed after bending and use.

Inappropriate use by users

Of course, in addition to the above problems are due to the reasons why manufacturers cut corners and the quality of mobile power supply itself is not good. The reasons for the potential hidden dangers of mobile power supply are also due to a small part of the users 'improper use.

As mentioned above, the 18650 battery itself is not resistant to overcharging, so excessive use and overcharging of mobile power supplies may lead to a shortening of its service life, and even a dangerous situation such as spontaneous combustion and explosion.

In addition, some friends put mobile power in a high-temperature, flammable environment, which is very dangerous. High temperatures and open fires can easily cause mobile power to explode, even if it is the best mobile power, reminding everyone to be vigilant. Especially in the current hot summer, the temperature is too high, and the mobile power supply will be more or less accompanied by heat when charging and discharging. This is a potential hidden danger that causes the mobile power supply to spontaneously ignite.

Conclusion:

However, it is not necessary to make waves of vegetation because of several mobile power explosions. In fact, the mobile power supply with good quality is still very safe. To constitute a fire and explosion, it must be based on harsh conditions. If you have to use mobile power, then when you buy mobile power, do not worry about money, must remember, recognize the big brand, the best is to use mobile power to the small partner information, safety first! I hope everyone can buy a nice mobile power supply.
