Laptop adapter voltage battery voltage is not it can be charged to the notebook? Influential?
Select the charger is not simply higher than the laptop battery can be, there is a limit, generally not more than 10%, that is, the books 14.8 battery, it is recommended to choose about 16V mobile power is better, although the charge may be slow Point, but the slow charging effect is the best. Of course, 19V can also be used, just not recommended.
First of all, the voltage instability on the computer damage, casually received the power of your computer may be scrapped, and now the notebook is generally 19v, not only the voltage, the current also provides
Is not higher than the laptop battery can be, theoretically speaking, but after all, the books of each book is not the same, the circuit also has a certain pressure drop, so choose the power adapter is based on the original power adapter voltage (plus or minus 5% Can also accept) to choose, choose too high voltage is not appropriate.
