Are the same nominal voltage power supply, the output current is different, can not be used in the same books on the Power supply voltage, the output current is different, can not be used in the same books. The basic principle is that the large nominal current supply can replace the small nominal current supply. It is estimated that some people would like to think that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, Oh, think of junior high school physics to know.（ AnenPower ）  When the books of high-load operation, the current larger, the books into the standby time, the current is smaller, large current power supply has enough current margin. On the contrary, some people use 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply, so this replacement is generally ...

What is the nominal voltage and current of the power adapter (hereinafter referred to as the power supply)? First of all, the general power supply of the nominal voltage, it is to point to open circuit output voltage, which is not connect any load, outside when no current output voltage, so can also be understood as the voltage is the upper limit of output voltage. ( AnenPower ) For use inside the power supply under the condition of the active voltage components, even if the mains voltage fluctuation, the output is also a constant value, as the market of small transformers, like the walkman with power supply, if the mains fluctuation, the output of the power supply will not then swings.  ( AnenPower ) In general ordinary real no-load voltage power adapter does not necessarily completely consistent, and nominal voltage because of the characteristics of electronic components can't completely consistent, so there is a certain error, error is smaller, the higher the consistency ...

Power adapter is a small portable electronic devices and electronic power supply power transformation equipment, general controlled by shell, transformer, inductor, capacitor, IC, PCB board and other components, it works by converting ac input dc output; According to the way of connection can be divided into the wall type and the desktop type. It is widely used in security camera, set-top box, router, lamp strip, massager, etc. Power adapter, also called external power supply, a small portable electronic devices and electronic power supply voltage transformation equipment, common in mobile phones, LCD display and laptop computers and other small electronic products.
