Power adapters are widely used in residential life, from the voltage regulator in the eighties to the charger for laptops today can be called power adapters, along with the rapid development of technology, the power adapter is now gradually getting smaller and smaller, but the functions it can provide remain unchanged, let's introduce the functions of the power adapter next.
Here is the content list:
The function of the power adapter
Use of the power adapter
The function of the power adapter
1. Power adapter can adjust the input and output voltage, the laptop power adapter can be for 100V-240V voltage range, that is, no matter where we are, the laptop can be used, no need for a power converter.
2. The output voltage of the power adapter is by the size of the laptop and the requirements of the electrical capacity, generally will choose a few amps to tens of amps ranging.
3. Power adapter can protect computer components, if there is no power adapter, the laptop directly into the socket to use will burn computer components and batteries, the main reason is the load and other issues, and the power adapter can control the current in the laptop requirements within the power load, which can ensure that its normal use of the process does not bring safety risks because of the power load.
4. The power adapter can protect the battery, the power adapter can be for the input voltage shunt and voltage stabilization, for the current of impurities and noise in the filter, to give the battery a stable voltage power, to further ensure the life of the battery. In the process of use, the power adapter will also send current to the machine to use as well as give battery charging, and the battery will be fully charged through the charging current control device to send a signal to the power adapter, thus forming a power failure, which is also one of the functions of the power adapter.
5. The power adapter can help cool down the laptop and will not form a series of safety accidents due to sudden power failure or other problems.
Use of the power adapter
1. Try to avoid using the power adapter outdoors or in harsh environments to prevent the power adapter from being exposed to sunlight or moisture.
2. Unplug the power adapter if it is not in use. This is because the long time power on will keep the power adapter in working condition, which will affect the final service life of the power adapter.
3. Although the power adapter is a wide range of operating voltage, marked from 100V-240V, but if the power adapter is used under extremely unstable voltage, it will also cause damage to the power adapter.
