Precautions TWO of Power Adapter

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 feasible in the general use, But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, above a CD-ROM to read the disk at full speed, plus at the same time To charge the battery, it is estimated that the danger, and at any time to touch your power is not already boiled eggs. So it is best not to use a small current instead of high current power supply.(AnenPower

Does The Power Adapter Plug In The Socket And Consumes Power?

With more and more electronic devices around us, a variety of power adapters are naturally inevitable. For the convenience of charging, many of us like to plug the power adapter into the socket, but it will be slow even if the device is not connected. Slow power consumption, then why does the power adapter consume power when it is empty? Left Center Right Remove click to add a caption Most power adapters belong to the switching power supply. The 220V is first rectified into DC power, then converted by high frequency, and coupled by pulse transformer, and unidirectional rectified output is low voltage DC. Even if there is no output current, the high frequency conversion section is still working and needs to consume some of the power. For example, the control circuit in the charger is mainly whether the sensing device is connected to the power adapter, and the control circuit is also working when the power adapter is not connected to...
