The purpose of the power adapter is to convert the high voltage at home into the low voltage suitable for the work of electronic products. Power adapter is the power supply conversion equipment of small portable electronic equipment and electronic appliances, which is generally composed of shell, power transformer and rectifier circuit.
The nominal voltage of the power supply refers to the open-circuit output voltage, that is, the voltage when there is no external load and no current output, so it can be understood that this voltage is the upper limit of the power supply output voltage. In the case of active voltage stabilizing elements used in the power supply, even if the mains voltage fluctuates, its output is also constant. Like small transformers on the market, such as walkman and other power supplies, if the mains voltage fluctuates, the output of the power supply will not fluctuate.
There is a nameplate on the power adapter, which indicates the power, input and output voltage, current and other indicators. Pay special attention to the range of input voltage. This is the so-called "travel power adapter". This feature is very useful if you go to countries where the market voltage is only 110V. Some aquatic laptops are only sold in the country of origin. There is no such compatible voltage design, or even a single input voltage of 110V, It will burn out when it is plugged in at 220V mains voltage in China.
