The difference between power adapter and charger
 
The power adapter generally refers to the power supply that converts our mains power to DC or low-voltage AC power required by appliances such as notebooks, mobile phones, monitors, routers, switches, etc.But the power adapter would be the charger if it is used for laptops and mobile phones.For most others applications, the power adapter is just a power supply. Let's first understand what a charger is and what is a power adapter before introducing the difference between a charger and a power adapter. Power adapter manufacturers will come to make an analysis for everyone:

Charger:
Charger usually refers to a device that converts alternating current into low-voltage direct current. It includes a control circuit that meets charging characteristics such as current limiting and voltage limiting. The charger is widely used in various fields, especially in the field of life is widely used in mobile phones, cameras and other common electrical appliances. It generally charges the battery directly without any intermediary equipment and devices. The flow of the charger is: constant current-constant voltage-trickle, three-stage intelligent charging. The three-stage charging theory in the charging process can greatly improve the charging efficiency of the battery, shorten the charging time, and effectively extend the battery life. Three-stage charging uses constant current charging, then constant voltage charging, and finally float charging for maintenance charging.
 
Power Adapter:
Most power adapters can automatically detect 100-240V AC (50/60Hz). The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It externally connects the power supply and connects to the host with a line. This can reduce the size and weight of the host. Only a few devices and appliances have the power supply built into the host. Inside. It is composed of power transformer and rectifier circuit internally, according to its output type can be divided into AC output type and DC output type; according to the connection method can be divided into wall type and desktop type. There is a nameplate on the power adapter, which shows the power, input and output voltage and current and other indicators, especially pay attention to the input voltage range.
