1. "Power adapters" of different specifications cannot be used universally. The key points are:
①The voltage must be the same, otherwise it will burn the electrical appliances or fail to work.
②The "output current" of the power adapter must be greater than the working current of the electrical appliance, otherwise, the power adapter will "overcurrent" and burn out.
③The interface of the power adapter and the electrical appliance must match, otherwise it cannot be connected.
④The positive and negative polarity should be the same to avoid accidents.
2. What kind of power adapter can be used universally?
It can be replaced if the voltage is appropriate and the current is not less than the original power adapter.
Appropriate voltage means that as long as the voltage of the power adapter is higher than the battery voltage of the notebook by 4V, it can be used. Otherwise, because the voltage is not enough, the notebook charging and protection circuit cannot open the working voltage difference.
The 11.1V battery requires a power adapter voltage of 15V or more, and a 14.8V battery requires a voltage of 19V or more.
Can the power adapter be universal? Just share it here. In summary, try to use the original charger as much as possible in your life. This is mainly for safety reasons. Most manufacturers will provide original adapters. If you can't find them, you can choose a power adapter of the same specification. Many people may not know how to choose a power adapter in the process of choosing a power adapter. We have talked about how to choose a power adapter before. You can take a look at it together.
