What Is the Difference Between Power Adapter and Charger?

2023.02.28
With the increase in technological advancements, we often come across terms such as power adapters and chargers. However, many people tend to use these terms interchangeably, but they are not the same thing.

Understanding the difference between a power adapter and a charger can be quite helpful when it comes to the proper use of electronic devices.
 

What Is a Power Adapter?


A power adapter is an external power supply that converts high-voltage AC power from an outlet into low-voltage DC power that can be used by electronic devices such as laptops, mobile phones, and tablets.

The power adapter also regulates the voltage and current required by the device to function correctly. Power adapters come in different shapes and sizes, and they can be used for various electronic devices.

For instance, if you own a laptop that requires a DC input, you will need a power adapter that can convert the AC voltage from the wall socket into the DC voltage that the laptop requires. Without the power adapter, the laptop will not function as the battery alone cannot power the laptop for an extended period.
 

What Is a Charger?


A charger is a device that charges a battery or a device's internal power source. Chargers are used to recharge batteries used in electronic devices such as mobile phones, laptops, and tablets.

For example, your mobile phone comes with a charger that can recharge the phone's battery. The charger receives power from the wall socket and converts the power into low-voltage DC power that the battery can store. The charger regulates the voltage and current that the battery requires to prevent overcharging or damaging the battery.

The Difference Between a Power Adapter and a Charger

 

Functionality


The primary difference between a power adapter and a charger is its functionality. A power adapter is used to convert high-voltage AC power from a wall socket into low-voltage DC power that electronic devices can use. On the other hand, a charger is used to recharge a battery or a device's internal power source.
 

The Output Voltage and Amperage


Power adapters have a specific output voltage and amperage that is required by the electronic device to function correctly. If the output voltage or amperage does not match the device's requirements, the device may not work correctly or may be damaged.

Chargers usually have a variable output voltage and amperage. This is because different batteries require different voltages and amperages to charge correctly.
 

Physical Appearance


Another difference is the physical appearance of the devices. Power adapters are usually larger in size than chargers. This is because power adapters have more components, such as transformers and rectifiers, that are required to convert high-voltage AC power into low-voltage DC power.

Chargers are smaller and more compact. This is because chargers only need to convert the power from the wall socket into low-voltage DC power that the battery can store. Chargers also have fewer components than power adapters.

It is also worth noting that power adapters are usually included with the electronic device at the time of purchase. In contrast, chargers may need to be purchased separately for some electronic devices, such as laptops and cameras.

Some electronic devices may use both a power adapter and a charger. For example, a laptop may use a power adapter to power the device and charge the battery, while the battery may be recharged using a separate charger.
 

Conclusion


Understanding the difference between these two devices can be beneficial when it comes to the proper use of electronic devices.

It is essential to use the correct device for its intended purpose and ensure that the output voltage and amperage match the electronic device's requirements to avoid damaging the device.
