Laptop power adapter, 19v ~ 2.37A. I bought a 19v, 3.42A, the battery is not harmful ah!
Plug can be compared with the original from the appearance, as long as the plug in good contact on the line. Positive and negative mark on the shell should have, and the old contrast or look at the multimeter.
Alternative principle: the voltage must be equal, the current can be large.
19v, 3.42A power adapter, can replace 19v, 2.37A power adapter, will not cause any damage to the battery, pay attention to their positive and negative polarity and plug to be exactly the same.
