The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays and notebook computers. So what is the disadvantage if the current of the power adapter is too large?

 

Is there any harm in the output current of the power adapter too large?

 

For the power adapter, the most important parameters are two: output voltage, output current.

 

Different specifications of the power adapter, if the voltage output voltage is different, there is no way to use it. So be sure to check the output voltage carefully before using the power adapter. The output voltage must be accurate. If the device is powered by 12V, the voltage of 5V will definitely not work. If the voltage is 24v, the device may burn out.

 

The power adapter output current is its nominal current, ie it provides the maximum current. The current supplied in actual use varies from load to load, but the maximum supply current cannot exceed its nominal current. The large current of the power adapter can replace the smaller current adapter, while the smaller one cannot work with the larger power adapter.
