The comparison Between Charger and Adapter

The charger is power supply equipment which will turn the alternating current (ac) into low voltage direct current. It is a static variable flow device which adopts the power electronic semiconductor devices to transfer the alternating current with fixed voltage and frequency into direct current.

It is applicable to small portable electronic equipment and electronic appliances' power supply transformation equipment. Adapter can be independent hardware interface equipment, and also can be information interface. Commonly used adapter usually has power adapter, Adapter Converter Switcher, etc.
