In the process of modularization, integration and miniaturization, no matter how the appearance and function of power adapter change, the five basic functions of a qualified laptop power adapter are the key to its passing the certification. Now let's see what five basic functions a qualified power adapter should have.

1. For the power adapter of notebook computer, its basic and most important function is to adjust the input and output voltage. According to the current international standard, a qualified laptop power adapter product can cope with the voltage range of 100V-240V, that is, no matter where the user is, the laptop is plug-and-play, without power converter. Only by meeting this design requirement can the new product meet the export production standards.

2. The basic function of laptop power adapter is to protect the laptop battery. A new type of adapter product, which has passed the test and certification, can shunt and stabilize the input voltage, filter impurities and clutters in the current, give stable voltage power to the battery, and can also bear the problems of voltage reversal when the battery is suddenly cut off, thus fully guaranteeing the service life of the battery. At the same time, in the process of using, the power adapter will also default to send current to the machine and charge the battery. When the battery is full, it will send signals to the adapter through the charging current control device, thus forming a power outage, which is also one of the functions of the power adapter.

3. Finally, any laptop power adapter certified by CCC must have, that is, through its own heat dissipation design to help the laptop cool down, so that its hardware in the cooling at the same time, not because of sudden power outage or other problems caused by safety incidents, for the voltage stability of the current can also be more convenient for the use of laptops.
