The use of power adapter
There are various types of switching power adapters in our life, but many people do not understand the relevant knowledge of power adapters. They are completely unaware of the specific application of switching power adapters. In fact, we should learn some of these knowledges of power supply in life, the following tips of power adapter should be popularized:
First of all, what is the use of the switching power adapter? Popularly speaking, the "voltage converter" converts the 220V AC power of the commercial power supply to a dozen volt DC power used by your notebook. It is not normal if your device be turned on automatically when you turn on the power supply!
The power adapter has power, but the computer should not be turned on immediately. It should be started after pressing the computer's power switching key, which is normal. It turns out that how much voltage is required accurately, that is why the wires coming out of the switching power supply have a variety of colors, which are used to distinguish different voltages and currents.
The switching power adapter is suitable or not, which depends on whether the interface between the power supply and the motherboard is suitable or not mainly. This is called "architecture". Different motherboard architectures have different power access rules, and the power must also be considered.
What kind of appliances are generally used: a power adapter is a power supply that turns the voltage of a certain power supply into the voltage you need and the appropriate current. Some adapters also have protection functions to limit current, voltage, and protect electrical equipment. Power adapters are generally used in places with high power requirements. Most of mobile phones are now used.
