Difference Between Adapter and Converter (With Table)

As the intricacy of contemporary technology grows, gadgets are built to meet a variety of criteria while adhering to a variety of standards. As a result, the gadgets are incompatible with the others, particularly at ports used to link devices for power supply, storage and retrieval, or simple communication. An adapter and a converter are two such examples of electrical devices with distinct functions.

Adapter vs Converter

The main difference between an adapter and a converter is the use of power. The aim of an adapter is to effectively make the electronics plugs fit into foreign outlets, whereas the task of a converter is to adjust the voltage present in an outlet to best match that of the electronics.

By employing a single plug, adapters make it possible to connect a peripheral device to a distinct jack on your computer. They are typically used to connect contemporary devices to a legacy port on an old system to a modern port. These adapters might be completely passive or incorporate active electronics.

Converters are active components since they not only facilitate connectivity but also modify the form of the medium flowing via the component. It could be potentially a physical component or a software component. The fundamental function of a converter is to convert a large or low amount of power voltage into the voltage required by a device.

Comparison Table Between Adapter and Converter

Parameters of ComparisonAdapterConverter
UsageAn adapter is a device that enables one plug to fit into another kind of terminal.A converter modifies the electricity so that it may be utilized at the intended location.
ComponentsAdapters include fewer components than converters.Converters have a substantially larger number of components.
Incorrect Device UsageThere are no issues as a result of using the incorrect adaptor.Inaccurate converters might result in significant harm.
ConnectionAn adapter connects a plug to a socket meant for a distinct plug type.A converter enables a device to be connected to a mains supply delivering a voltage that differs from the voltage for which the item was actually built for.
Voltage Conversion CapabilityAdapters do not have the capacity to automatically make alternations between AC and DC or high and low voltage outputs.By correcting the electric signal, converters can indeed convert any DC voltage to AC or the other way around.

What is an Adapter?

Multiple kinds of plugs are utilized in various parts of the earth. This is not due to a technical problem. Distinct nations began to develop different types of plugs on their own, and after several wall outlets were installed, it was too complicated to change everything to a single global standard.

To address this issue, an adaptor was built. An adapter is a device that enables a plug to be connected to a distinct kind of socket. Thousands of tourists traveling across nations frequently need to acquire these adapters in order to connect electrical gadgets from their native country into outlets in other nations.

On the market, there are several types of adapters that are utilized for specialized reasons. Adapters of many varieties include video adapters, electrical adapters, network adapters and audio adapters that function as per the person’s preference. An adapter contains fewer components. It’s very effortless to use and work with as a result of this. In certain circumstances, using the wrong adaptor may not result in any difficulties. As a result, the tourist does not have to be concerned.

What is a Converter?

Not only do various nations utilize various types of plugs, but the specifications for mains power vary as well. The majority of nations utilize AC currents with an RMS voltage of 230 V and a frequency of 50 Hz. RMS voltages of 220 or 240 V are also used in several places.

Certain devices are designed to operate at either 120 V or 230 V. As a result, if a person decides to plug such a device into the mains power of another country, a converter may be necessary. In a converter, a transformer is designed to step up or step down the voltage to an appropriate value. However, most contemporary devices can work at both voltage levels.

Convertor types are commonly classified as high-wattage converters and low-wattage converters for usage with high-wattage devices and low-wattage devices respectively. Because converters actively participate in the transfer of media across interfaces, any flaw in the converter destroys the media’s content. This might lead to either equipment failure or data loss.

Main Differences Between Adapter and Converter

  1. An adapter is a gadget that is used to link two items for charging reasons. A converter, on the other hand, is a gadget that is utilized to adjust the voltage from high or low to the appropriate normal voltage.
  2. Adapters cannot mechanically switch between alternating current and Direct current or high and low voltage outputs, but converters can easily convert any Direct current voltage to alternating current or the other way around by rectifying the electric signal.
  3. An adapter connects a plug to a socket meant for another plug type, while A converter enables a device to be connected to the main power supply with a voltage that differs from the device’s standard voltage.
  4. When the wrong adaptor is used, it may not create any difficulties. On the other hand, in some circumstances, using the wrong converter may result in serious complications.
  5. Adapters are generally compact and lightweight, often including simply a socket; on the other hand, converters are larger in size and design because they contain a circuit board for switching or limiting voltage.
  6. An adapter contains lesser components. A converter, on the other hand, has a greater number of components.


Different nations throughout the globe have different standards for distributing mains electricity. Fluctuations in the voltage and frequency of the distributed alternating current cause these variations. Furthermore, various countries employ different plug kinds for connecting equipment.

Adapters and converters are gadgets that enable individuals to connect electrical equipment manufactured in one nation to the mains electrical systems in other nations.The adapter and converter are two little electrical devices that serve two distinct functions. Both of these gadgets are ideal for traveling. However, the functionalities of the two gadgets are not the same.
