time2019/05/10
- The function of the power adapter is to convert the high voltage in the home into a stable low voltage that can work, so that he can work normally.
The power adapter (hereafter referred to as the adapt tag above there are generally several items that need attention.
First, the adapt model, such as this adapt model is XVE-120100 tells a few information, that is, manufacturers, wattage, etc., XVE is generally the ## company code, 120100 is to explain that this adapt12W050200 is 10W.
Second, the adaptINPUT input) is generally 100-240V~50-60Hz. This means that the adapt can work normally under the voltage of 100V-240V.
Third, adaptOUTPUT output) two numbers can quickly calculate the adapt wattage, for example, this adapt voltage 12V * current 1A = 12W power) that this power is 12Wadapt.
Most laptop power adapters can be used for 100240V AC (50/60Hz. Most laptops have external power supplies, and a power cord is connected to the host, which can reduce the size and weight of the mainframe. The model has a power supply built into the main unit.
There is a nameplate on the power adapter, which indicates the power, input and output voltage and current quantity. Pay special attention to the input voltage range. This is called the travel power adapter. If the mains voltage is only 110V, this feature will be used. Very useful. Some parallel laptops are sold only in the country of origin without this compatible voltage design, even with a single input voltage of 110V, the country's 220V mains voltage will be burned when plugged in.
Summary: The role of the power adapter is to convert the high voltage in the home into a stable low voltage that can work, so that he can work normally. Without it, it will bring a lot of convenience to my daily use. This article mainly introduces the role, composition and application of the power adapter and some issues to be aware of when using the power adapter.
