70W Notebook Power Adapter 20V 3.5A Laptop Charger

70W Notebook Power Adapter 20V 3.5A Laptop Charger

As For the composition of notebook power adapter, the first is the varistor of laptop adapter. Its function is that when the external voltage is too high, the varistor resistance value quickly becomes very small, and the fuse in series with the varistor is blown, so as to protect other circuits from being burnt. The second is its fuse, which is 2.5a/250v. When the current in the circuit is too large, the fuse will blow to protect other components. Moreover, its inductance coil (also known as choke) is mainly used to reduce electromagnetic interference.
