What is the difference between an adapter and a charger?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.04.12
Adapters and chargers are two common electronic devices that are similar in appearance and function, but their functions and principles are different. This article will introduce the differences between adapters and chargers from several aspects.



1. Different functions

The functions of adapters and chargers are different. An adapter is a device that can convert the output voltage and current of a power supply into a voltage and current that meets the requirements of the device. It is usually used for supplying power to electronic devices. A charger is a device that can convert the voltage and current output from a power source into a voltage and current that meets the requirements of a charging device. It is usually used to charge batteries or mobile devices.

2. Different output voltage and current

The output voltage and current of adapters and chargers also differ. Adapters typically output constant voltage and current to power electronic devices. The charger outputs different voltages and currents according to the requirements of the charging device, in order to charge the battery or mobile device.

3. Different structures and appearances

The structure and appearance of adapters and chargers are also different. An adapter is usually a small box shaped device with a plug and socket that can be directly inserted into a power outlet and electronic device. A charger is usually a device with a charging cable, which needs to be connected to the power supply and charging device in order to achieve charging function.

4. Different application ranges

The applicability range of adapters and chargers also varies. Adapters are usually used to power electronic devices such as computers, routers, speakers, etc. Their voltage and current requirements vary, requiring the use of different adapters. And chargers are used to charge batteries or mobile devices, such as smartphones, tablets, cameras, etc., and their charging requirements are also different, requiring the use of different chargers.

In summary, although adapters and chargers are similar in appearance and function, they differ in their functions, output voltage and current, structure and appearance, and applicability. Understanding their differences can help us better use them, avoid incorrect use or selection of devices, and thus ensure the safety of both devices and users.
