it is best not to use low current power adapter supply instead of high-current power supply

nderstanding of these concepts, we can determine the second issue of this article

. The same nominal power supply voltage, output current is different from the same can not be used in the books. The basic principle is that a large nominal current of the power can replace the small nominal current power supply. Some friends are misunderstood, that a large nominal current of the power will burn books, because the current big thing. How much current is actually the Ac adapter Acer laptop ac adaptersame in the case of the voltage depends on the load, that is, the work books, when the books when the high-load operation, the current larger, the books go into standby when the current is smaller, short current equal increase in the books The voltage divided by the books on the equivalent resistance. Nominal current of the power supply has a large enough current margin, will not replace the current power after a small nominal output voltage is too low or overheating situation. On the contrary, with a small current power supply to replace the current existence of such a large risk. But some friends instead of 72w with 56w of power have no problem with it because the design of the power adapter is usually left a certain margin, the load must be less than the power supply power, so this place is in general use feasible, but the remaining power supply power margin to a few, the books once you pick a lot of peripherals, such as the two usb hard drives, and cpu at full speed, then there is a base, the above read the disk to a drive at full speed, then with the same time charging the battery, estimated to dangerous, to be ready to feel the power you are not already boiled eggs. 72w more than the 16w 56w adapter is to cope with such situations. So it is best not to use low current power supply instead of high-current power supply. If you really do, conditional friends can think of ways to Test your books, when the maximum consumption of the actual needs of current measurement method is very simple, a socket, a plug, a current meter, a few wires, a soldering iron can be. If the nominal current in your power within, of course, is safe.
