Are the same nominal laptop ac adapter voltage, output current differences, can be used in the same notebook?
The underlying principle is the nominal current of small power can be replaced by a large nominal current of the power. It might be misunderstood, someone thinks great nominal current of the power will burn Notebook, actually how large the current depends on the load in the case of the same voltage, that is, the work of the laptop, the current was bigger when the notebook in a high-load operation and smaller when the laptop turned into standby state, in short, the current equals to the voltage added to the notebook divide by the notebook’s equivalent resistance. Large nominal current laptop ac adapter has sufficient current margin and will not overheating or low output voltage after replace a small nominal current power. If you use a small current replaced a high-current adapter will ouccers such dangerous. But some friends instead of 72w with a 56w adapter is also no problem, that is because laptop power adapter is usually designed to leave a margin, load power must be less than the p
