Is the power adapter universal?
Update Time:2019-05-14
The voltage is appropriate and the current is not less than the power adapter of the original power supply. The voltage of the power adapter can be used as long as it is higher than the battery voltage of the notebook by 4V or more.

Nowadays, more and more electrical equipment in my life needs to use a power adapter. There are also many mobile devices that almost always use a power adapter. Then, can the power adapter be universal? The technical staff of Shenzhen Lianyunda Electronics Co., Ltd. will explain to you that the power adapter can be used universally.

First, different specifications of the power adapter can not be universal

1 The voltage must be the same, otherwise it will burn the appliance or it will not work.

2 The output current of the power adapter must be greater than the operating current of the appliance. Otherwise, the power adapter will “overcurrent” and burn out.

3 The power adapter must match the interface of the appliance, otherwise it will not be connected.

4 The positive and negative polarities should be consistent to avoid accidents.

Second, what kind of power adapter can be used?

The voltage is appropriate and the current is not less than the power adapter of the original power supply. The proper meaning of the voltage means that the voltage of the power adapter can be used as long as it is higher than the battery voltage of the notebook by 4V or more. Otherwise, because the voltage is not enough, the working pressure difference required for the notebook charging and the maintenance circuit cannot be opened.
