OEM 7.5mm5.0mm 90w Power Charger For Hp Notebook

• Most mobile PC power adapters can automatically detect 100 ~ 240V ac (50/60hz). Basically all mobile PCS put the Power Supply outside, with a line and the host connection, so you can reduce the size and weight of the host, only a few models put the power inside the host. On the power adapter, there is a nameplate indicating the power, input/output voltage and current flow, with special attention to the input voltage range. This is known as a "travel power adapter".
  

• How to use the adapter pattern:
  A class is used to inherit the interface and the known class at the same time, using the methods and properties defined in the known class to realize the definition of the interface (mainly using the method of overloading interface methods). This class is used as a base class for other business classes, where interfaces and known classes are adapted. If a known class changes, simply modify the class adapter to satisfy the implementation of the interface.
