Voltage different different brand notebook power adapter is not the same, even if the power adapter interface is similar, also cannot apply different brands of laptop power adapter for power supply. Different different brand notebook power adapter current is also not the same. The interface is the most important, excuse if there is wrong is certainly will appear all sorts of all sorts of problems. Followed by the voltage, as long as the voltage is close to 5%, should can be generic. In addition is the current, the big electric current can be used in small current machine, but time shoulds not be too long. Finally is the interface compatibility issues, swap is certainly not possible. So the main cause of laptop power adapter is general interface, such as voltage, current three reasons. Believe you can after read this article on a laptop power adapter is not universal problems have a further understanding.
