The difference between a charger and a power adapter
Jun 19, 2018

The difference between the charger and the power adapter, in our life, has a lot of electronic products, which are the least used by the charger and the power adapter, but many people don't know much about the difference between the two.


One, what is a charger?

A charger usually refers to a device that converts AC to low voltage DC. It is a special DC power supply for rechargeable batteries, which includes a control circuit that limits the current and limits the voltage to meet the charging characteristics. According to the battery condition, the current limit may be limited, and voltage limit may be required.

Chargers are widely used in various fields, especially in the field of life, which are widely used in electric appliances, flashlights and other common appliances. It usually charges the battery directly, without any intermediary equipment or device.


Two. What is an adapter?

The power adapter is a power supply converter for the small portable electronic equipment and electronic appliances. It puts the power supply outside and connects the mainframe with the mainframe. In this way, the volume and weight of the mainframe can be reduced. Only a few devices and electrical appliances are built in the mainframe.

The power adapter is a power converter with voltage variable, rectifier and voltage regulator, and the output is DC. It can be understood as a low voltage stable voltage power supply when the power is satisfied. It is widely used in routers, telephone phone servers, game consoles, language repeater, Walkman, notebook, mobile phone and other devices. Most power adapters can automatically detect 100 to 240V alternating current (50/60Hz).


Three, the difference between the charger and the power adapter

There is a difference between the power adapter and the charger. The power adapter directly supplies power to the electrical appliance, and requires a stable voltage, so it is a regulated power supply. The power adapter can be used as a charger because the internal resistance of the power adapter and the battery is larger, the characteristic "soft" and "mutual adaptation" are not the problem.

The charger inside the cell phone and computer does not include the charging control circuit, and the charging control circuit is usually put on the host computer. So the charger and the laptop charger are actually a power adapter. It is not included in the charge control circuit. The power adapter such as the natural cell phone charger and the notebook charger, such as the host, is actually a power adapter. The power supply used to supply electrical appliances and equipment is called a charger.


The difference between the charger and the power adapter: the charger contains the function of the power adapter, but the charger has a control circuit that has constant current, constant voltage and so on to meet the charging characteristics. After knowing the above contents, I believe you have a clear understanding of the difference between charger and adapter.
