The life span of a power adapter is just like the life span of a human being, it is impossible to predict the exact life span, but many big data analysis reports have the concept of average life span. Under normal use, the power adapter can last 2-3 years, if not used properly will directly affect the life of the power adapter. Let us now introduce how to use the power adapter properly.

How to use the power adapter correctly？
1. Power adapters of different laptop models cannot be mixed
Different types of laptop power adapters have some differences in voltage and current values, so they should not be mixed. Otherwise, it is likely to cause the laptop's battery to be undercharged and other phenomena, or to burn out the laptop's motherboard or other hardware.
2. Reasonable charging of the power adapter
When the laptop's battery is charging, you should try not to run large 3D games, to avoid the power adapter output power surplus is not enough and lead to slow battery charging speed.
3. The power adapter should be stopped in time if it is abnormal
When the power adapter makes a lot of noise or even smoke, it should be a malfunction of the power adapter and should be stopped immediately and contacted by a professional engineer before it is put into use again.
Precautions for using the power adapter
1. Try to avoid using the power adapter in a wet or easy to contact with water environment, except for the waterproof power adapter of course.
2. Do not use and power adapter that does not match the input voltage, so as not to cause the power adapter input excessive current or voltage phenomenon and damage.
3. When using the power adapter, should protect the wire not to overbend or fold dead, and friction.
4. The power adapter should be avoided in the environment of direct sunlight.
5. When not using the power adapter, should try to cut off the power supply to reduce the internal loss of power. This not only extends the life of the power adapter but also saves resources.
Components of the power adapter
1. Varistor, its function is when the external voltage of the power adapter is too high, the resistance of the varistor quickly becomes very small, and the fuse in series with the varistor is blown, thus protecting the other circuits of the power adapter from being burned.
2. Fuse, when the current in the power adapter circuit is too high, the fuse will blow to protect other components.
3. Inductive coils, whose main function is to reduce electromagnetic interference.
4. Rectifier bridge, the role is to change 220V AC into DC.
5. Filter capacitor, the role is to filter out the AC ripple in the DC power supply adapter, so that the circuit works more reliably.
