There are many benefits to the power adapter, but many people confuse the power adapter with the battery. In fact, the two are fundamentally different. The battery is used to reserve power, and the power adapter is a conversion system between the power supply and the battery. If there is no power adapter, once the voltage is unstable, our computer, notebook, TV, etc. will be burned. Therefore, the power adapter is a good protection for our household appliances, and it also improves the safety of the electrical appliances. In addition to improving the safety performance of electrical appliances, it is the protection of our own body. Imagine if our electrical appliances do not have a power adapter, once the current is too large and suddenly interrupted, it may cause the electrical appliance to explode or spark, etc. The blasting or fire has a great threat to our lives and health. It can be said that having a power adapter is equivalent to insuring our home appliances. Never worry about accidents anymore.
