Usually more and more electrical equipment in my life needs to be applied to the power adapter. There are a lot of mobile devices, it will be applied to the power adapter. So the power adapter can be universal? The following is a small series for you to explain the power adapter can be universal.

1. different specifications of the power adapter can not be universal

The voltage must be different, otherwise it will burn the electrical appliances, or can not work.

The output current of the power adapter must be greater than the working current of the electrical appliance, otherwise, the power adapter will be "overcurrent" and burn out.

The power adapter and the interface of the electrical appliance must match, otherwise it cannot be connected.

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

2. what kind of power adapter can universal?

The voltage is appropriate, the current is not less than the original power adapter, you can exchange. The meaning of proper voltage means that the voltage of the power adapter only needs to be higher than the battery voltage of the notebook 4V or more, and it can be used. Otherwise, due to insufficient voltage, the working pressure difference required by the charging and maintenance circuit of the notebook cannot be opened.
