The difference between power adapter and power supply charger

Increasingly developed portable electronic products are increasingly demanding for power adapter and power supply charger quality and charge stability. 

Power adapter is a transformer, rectifier and regulator power converter, The output of the DC, to meet the power of the case can be understood as low-voltage power supply. Let's talk about what the next power adapter is. Charger is usually referred to as a switch into low-voltage direct current equipment, which includes the current limit, limiting voltage and other charging characteristics to meet the control circuit, What is the charger? What is the relationship between the two and the difference between each other.

Power adapter

Common power adapter on the market is through the transformer, rectifier and regulator power converter, the output is DC, in the case of power can be understood as low-voltage power supply. Power adapter is widely used in routers, telephone sub-machine, game consoles, language repeaters, Walkman, notebooks, mobile phones and other equipment. Most of the power adapter can automatically detect 100 ~ 240V AC (50 / 60Hz).

    Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, it is external power supply, with a line and the host connection,which can reduce the size and weight of the host, only a very small number of devices and electrical power built in the host Inside. It is composed of internal power transformer and rectifier circuit,according to its output type can be divided into AC output type and DC output type.

Power supply charger

Power supply charger usually refers to a conversion of alternating current into low-voltage direct current equipment,the charger is a rechargeable battery with a dedicated DC power supply, which includes the current limit, limiting voltage and other charging character is tics to meet the control circuit.

  Power supply chargers are widely used in various fields,especially in the field of life is widely used in electric vehicles,flashlights and other common appliances. It is generally a direct charge to the battery, not through any intermediary equipment and devices.

  Power supply charger flow is: constant current - constant pressure -trickle, third-order 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 can effectively extend the battery life. Three-stage charge using the first constant current charging, and then constant voltage charging, and finally the use of floating charge maintenance charge. Generally divided into fast charging, make up the charge, trickle charge three stages.
