Now many people are worried about the explosion of charging treasure. Let me analyze it for you: first of all, why did the lithium battery explode? Because the battery is overheated, a large amount of gas is generated inside, and it will explode when the pressure reaches a certain height. What causes the battery to overheat? Overcharge, overdischarge, short circuit, mechanical damage (such as nailing). In fact, in order to ensure the safety of users, there must be a protection circuit inside the charging treasure. In the case of overcharge, overdischarge or short circuit, the circuit will automatically cut off the power supply for protection. Therefore, normal use is very safe. But if the quality of this protection circuit is not good and it is damaged in advance, it will be unreliable. So don't buy cheap informal products. During normal use, it is necessary to pay attention to the supervision during charging. When abnormal temperature rise is found, the power supply must be cut off in time to prevent tragedies such as explosion and fire.
