In recent years, fires caused by inferior power adapters are very common. Most people complain that the inferior products of unscrupulous power adapter manufacturers are harmful to people. In fact, improper use of users is the most direct cause of fires. What happened to the fire caused by the power adapter? How to prevent it?
Dry connection of the power adapter causes excessive heat
The power adapter must be an active circuit, which completes the conversion of electrical energy, such as step-down or rectification. This part of the circuit will generate a certain load, and in many inferior power adapter circuits, manufacturers have not added high temperature countermeasures to prevent the continuous operation of the load. In this way, the power adapter will generate heat even when it is actually connected to the power supply but not charged. When it is heated to a certain extent, it will cause damage to the internal circuit, and many of this damage is also accompanied by a short circuit. This short circuit occurs. The occurrence of this phenomenon is very harmful to the circuits in your own room. If there is no fuse or air brake, the possibility of fire is very high.
Excessive charging causes the battery to rupture and explode
Overcharging will also cause the power adapter to generate huge heat and its consequences have been explained above, but at the same time, it should be known that this kind of overcharging is also a kind of damage to the battery. If the charging time is too long, the battery may explode. Most of the current batteries use inert lithium to maintain power. Once burned, this lithium element will be activated and rapidly oxidized in the air and generates heat. This is what can cause a fire.
