China dc power adapter factory said that power adapters are widely used in residents' lives. With the development of technology, current power adapters are gradually getting smaller and smaller, but the functions they can provide have not changed. Today, China dc power adapter factories share power function of the adapter.

1. Adjust the input and output voltage. According to the China dc power adapter factory, the power adapter of the notebook computer can cope with the voltage range of 100V-240V, and the notebook computer can use the power supply at any time.
2. Protect computer components. The China dc power adapter factory believes that if there is no power adapter, plugging the notebook directly into the socket will burn the original and the battery, and the power adapter will control the current within the power load required by the notebook to ensure that it is in the process of normal use. Do not bring security risks due to power load;
3. Protect the battery. Divide and stabilize the input voltage, filter impurities and clutter in the current, and give the battery a stable voltage power. During use, the power adapter will supply current to the machine for use and battery charging by default. After the battery is fully charged, it will send a signal to the adapter through the charging current control device to form a power outage.
4. China dc power adapter factory said that the power adapter can also help the notebook computer to cool down, and it will not cause a safety accident due to sudden power failure or other problems. The current provided by the voltage regulator can also be more convenient for the notebook computer to use.
