Why did the portable power supply explode?

Recently, Guangzhou metro will recharge treasure mobile phone power included in the category of dangerous goods, metro broadcast cycle, constantly reminds passengers don't use mobile power charging on the subway. Before that, as prescribed by the Guangzhou metro station of dangerous goods include gasoline, kerosene, days that water and other flammable items.

Since when, mobile power supply with inflammable and explosive dangerous goods on the equals sign!Want to know, in the subway station entrances and exits of all more or less a few vendors in selling mobile phone charging treasure, this let a person think of dying, his chuai in bag, pocket of mobile power supply, when sometime, became a timing bomb?

Why do mobile power spontaneous combustion and explosion?

Fire and explosion are often happen in low price, poor mobile power supply, because the manufacture of these inferior products profiteers to profiteering, in the place such as batteries, circuit and the wire to move hands and feet, the personal and property safety of us constitutes the great threat.

Terrible bad batteries

Batteries is the core of the mobile power supply, at present, there are two main types of mobile power supply can be used in batteries, is a kind of cylindrical shape design, 18 mm in diameter, height 65 mm, the "18650" batteries, batteries, is another kind of polymer material it and mobile phones battery very similar to that of general is square shape.The battery chemistry more stable, more safe.

Compared to two kinds of batteries is qualitative, mobile power supply about 60% currently on the market are using 18650 batteries, two kinds of products are safe enough in theory.

Of course,18650 battery Itself is not resistant to overcharge, refurbished products of fire and explosion probability exists, the copycat millet mobile power explosion event is the most telling.In particular, in the case of unscrupulous merchants had hands and feet, the quality of the mobile power supply is more security.

Using inferior batteries manufacturing mobile power supply, besides can lead to less power, loss fast, there exists a problem in safety performance, the explosion would happen.Especially the large capacity mobile power supply, once an explosion, consequence is very serious.So when the choose and buy mobile power must choose batteries excellent product.

Inferior wire short circuit

As a child, I bought a lot of one or two dollars of headphones, these headphones wire was peeling in a few days.The short thread of mobile power supply is the same reason.Inferior wire after bending, use is easy to deformation.

User's improper use

, of course, in addition to the above problem is due to the manufacturers to cut corners, the cause of the mobile power supply itself quality closes nevertheless, mobile power supply potential reason, also has a small part of improper use had to blame the user.

Mentioned above, 18650 battery itself is not overcharge resistance, so the overuse of mobile power supply, charging too much, and so on and so forth are likely to lead to the service life shortened, appear even spontaneous combustion, explosion and other dangerous situations.

In addition, some friends put mobile power supply in high temperature, flammable environment, it is very dangerous.High temperature, bright fire to explode easily lead to mobile power supply, even so is the best mobile power supply, remind everyone must remain vigilant.Especially now sorching summer, the temperature is too high, mobile power supply in charge, discharge, or more or less will be accompanied by fever, it is lead to mobile power potential spontaneous combustion explosion hazard.

Conclusion:

However, don't because of several mobile power of spontaneous combustion, the explosion ', actually qualified mobile power supply is very safe, if you want to fire, explosion, must be based on tough conditions.If you must use a mobile power supply, when buying mobile power supply, don't love money, be sure to keep in mind, look for the big brands, it is best to use a friend information of mobile power supply, safe!Hope everybody can get to the heart of grace mobile power supply.
