Different types of laptop chargers [Explained]

Laptops are small, portable electronics with rechargeable batteries as their own power source. These batteries have a limited lifespan before requiring recharging. Power adapters for laptops are used for this and are plugged into wall sockets. There are many laptop brands available, and each one utilizes a unique kind and model of adapter. On their retail websites, the majority of manufacturers provide laptop components and accessories. Laptop adapters may also be purchased from inexpensive computer hardware distributors and retail electronics retailers. Adapters and cables may also be found on auction websites like eBay. Finding the appropriate sort of adapter requires investigation when it’s time to replace an old one with a new one. Owners should verify their laptop’s model number, voltage, and amperage requirements before looking for an adapter.
Using this information, you may search online for a suitable laptop adapter. A laptop’s needed voltage and the voltage of the adapter must match. An adapter’s amperage may be equal to or more than what is needed. Owners of laptops need to additionally purchase an adaptor with the appropriate connection type. The most typical connection type for a laptop computer is the cylindrical connector tip or USB-C. Another option is to buy a universal power adapter, which has numerous connection tips and can adjust its power settings to the laptop.

Computers Run on DC Power

Direct Current (DC) electricity is required to run all laptops. The electrical energy that continually flows in a single direction is known as DC. The majority of wall outlets employ Alternating Electricity (AC), which produces a positive flow of current despite its continual variation. An adapter is needed to change the wall outlet’s current to DC power since laptops cannot operate on this form of power.
The little, bulky black box attached to the cords that go from the laptop to the wall socket for charging the battery is the adaptor. The laptop is able to consume AC power from a typical wall plug thanks to these components. DC adapters are also available for outlets that provide DC power.

Various Laptop Adapter Types

The AC adapter and the DC adapter are the two major kinds of power adapters that are used by laptops. These converters, which are often referred to as chargers, assist in transforming the power from the wall socket into a form that the laptop can use.

Ac Adapters

The AC adapter transforms the AC electricity present in most houses’ wall outlets into the DC power needed by the majority of small appliances. DC electricity is used by laptops, smartphones, computers, and DVD players. This is the sort of power that batteries deliver, which is what most laptops rely on to function when the user is on the go.

Dc Adapters

It seems that a DC adapter is not required when plugging in a laptop since DC power is what they run on. However, the majority of DC power sources provide a voltage that is insufficient for a laptop’s requirements. To take that electricity and transform it into a higher voltage that the laptop can use to operate or charge its battery, a DC power adapter is needed. Cars, airplane plugs, solar power systems, and batteries all use DC electricity.

Adapters for Universal Power

A universal power adapter is an additional choice for laptop users. Despite being more costly, these adapters can work with any voltage and power source. Theoretically, every laptop should be compatible with universal adapters. They are thus quite practical, particularly for those who regularly travel and are uncertain of their next source of power. In order to accommodate a number of laptops, universal adapters can come with a variety of connection types. Finding the right adapter for your laptop might be challenging since so many models employ various connection types.

Choosing the Correct Adapter Model

Given the wide variety of adapters available, it’s critical to confirm the kind of adaptor a laptop needs before making a purchase. The majority of adapters are sold for a certain laptop maker and model. Additionally, they will indicate the adapter’s voltage, current, and polarity. Owners of laptops may choose the right adapter for their machines in this manner. Checking the laptop’s model number and power requirements can help you choose the right adapter.

  1. Identify the model of the computer. This is often written on a little sticker that is attached to the laptop’s bottom.
  2. Obtain the laptop’s power needs. This is also written on a little sticker that is attached to the laptop’s bottom. It could also be printed next to the USB port on a laptop. Look for the appropriate voltage and amperage.
  3. To find out whether there are appropriate adapters available, look up the model number online. The laptop’s requirements must be met by the voltage and amperage of the adapter.
    Compare the laptop adapter’s connection type to any other adapters you can find online. To make sure the adapter can connect to the laptop, they must be the same size.

Regarding Voltage

What draws electrical energy into the laptop is voltage. It resembles a paddleboat’s wheels, which revolve and propel the paddleboat over the water. The paddleboat in this instance is really a group of electrons. The adapter won’t be able to generate the proper charge required to suck electrical energy into the laptop if the voltage of the laptop differs from that supplied by the adapter. It’s crucial to choose the proper voltage for a laptop adapter in order to prevent the electricity from shorting out the computer. The circuits in the laptop will be overloaded by an excessive voltage. At that time, owners will need more than simply a new adaptor.

Regarding Amperage

Amperage, sometimes referred to as current, provides the laptop with the necessary power to function. It refers to how much electricity is pumped into the laptop at any one time. To power all of the circuits within a laptop, there must be a sufficient stream of reliable electricity. Voltage is often used to gauge the laptop’s potential energy consumption. Laptop power adapters must have an amperage that is equal to or more than the laptop’s requirements.

kind of connectors

Make sure the connection will fit the laptop’s power port while searching for a new laptop adapter. Although DC power connections are used by all laptops, not all connectors are created the same.

Types of Laptop Connectors

Cylindrical Connectors

They are insulated, hollow cylinder that attaches to the laptop power port and go by many other names, including barrel connectors, sleeves, tips, and coaxial power connectors.

Snap and Lock Connector

This connection, which has three or four pins, is also known as a Kycon 3-pin and 4-pin DC power plug.

Molex Connector

A flat, rectangular box made of plastic with 3, 4, or 6 terminals houses multiple insulated electrical cables, which are often used to power portable computers.

USB connector

A hollow, rectangular metal tip with two or more flat metal pins within makes up the USB connection.

Some brands will feature unique, specialized connection tips for their laptop adapters. Finding a cheap adaptor may become more difficult as a result, but it is still doable. The most prevalent form of connection used in laptops is the cylindrical connector. Additionally, USB connectors are often used as power outlets for laptops and other electronic devices.
On eBay, there are dozens of various laptop power adapter models and varieties to choose from. You might research in-flight DC power adapters or simply purchase a new laptop adapter. These adapters are included in the category of laptop power adapters and chargers. Simply click on Electronics from the home page to access this category. From there, choose Laptop Power Adapters & Chargers under Computers, Tablets & Networking.


Despite being portable, laptops need power connections and adapters to recharge their batteries. AC and DC power adapters are the two primary categories of laptop adapters. They all transform electrical energy from a power source into a form that the laptop can use. The appropriate voltage, connection type, and amperage must be supplied via these adapters. There are several distinct connection types, but only one of them will function with a certain laptop. The owner of the laptop may enable the save a search option to send an email notification when a matching adapter is offered if the right style and model of adapter cannot be found on eBay or they can also buy it on Amazon.
