Recently, there are news reports that some consumers' mobile power supply exploded or burned, and the flight attendant died of electric shock when charging with IPONE5, which reflects the hidden dangers of the safety of electronic products. So why does the power bank explode or burn, what is the reason? Let's discuss with you the main factors that will explode!
There are two main aspects that affect the safety of mobile power: battery cells and PCB boards.
1. Battery: The battery is the core of the entire mobile power supply. There are currently two types of batteries, one is 18650 batteries, and the other is polymer batteries. The vast majority of high-end mobile power supplies currently use polymers The battery cell is used as a mobile power source. In terms of safety, the polymer battery cell is much better than the 18650 battery cell, and the general explosion-producing battery cells are also 18650 battery cells. A good lithium polymer cell does not contain liquid electrolyte inside the battery, and there is no battery leakage problem. The battery can be bent and deformed, with a long service life and high safety. If there is a quality problem, it will only burn and not explode. But in Taobao ’s dozen or twenty mobile power banks with a capacity of 10,000ma, consumers should be careful because such businesses are either virtual capacity or inferior and cheap “garbage batteries†called “garbage batteriesâ€. In fact, it is a waste battery purchased. This kind of battery has been used and has been aging. If it is used frequently, it will generate high heat. Under high heat, the expansion coefficient of the battery will increase, and at this time, it may explode.
2.PCB board: The PCB board is the protection god of the battery core, which guarantees the protection function of the battery core to stabilize and stabilize the current, overload, overcurrent, overcharge, overtemperature and short circuit protection. The good board has the largest protection for the battery core. Protection, otherwise there will be other problems such as explosion or burning.
Therefore, whether the power bank will explode or burn depends mainly on the quality of the materials. Here I warn you not to buy junk products for the sake of being cheap and cheap. The editor recommends to everyone the mobile power bank, which is of high quality and low price. It uses high-quality imported A-level batteries and PCB boards, so you can buy it with peace of mind and use it with confidence!
