Buyer’s Guide

How to choose the
best laptop power supply

What is the Purpose Of A Laptop Power Supply?

The power supply unit (PSU) converts electricity into usable electrical current. Most laptops require two types of PSUs; AC adapters and battery chargers. An AC adapter plugs directly into a wall socket while a battery charger uses batteries to store energy. Both units convert alternating current (AC) to direct current (DC).

How Does a PSU Work?

Most modern computers run on DC voltage which is converted to AC using a transformer. The transformer has coils inside that produce magnetic fields. As the electrons flow through these coils, they create a changing field around the coil. This creates an electric potential between the positive and negative terminals of the transformer. The output of the transformer is connected to the motherboard via a connector called a plug. The plug contains pins that connect to specific points on the motherboard. Each pin represents a different point on the motherboard where the signal must be sent. For example, there could be four pins representing the CPU, memory, video card, and hard drive.

Types of PSUs

There are three main types of PSUs available today. First, we have the standard type which comes with most laptops. Second, we have the modular type which consists of multiple components that can be added together. Third, we have the external type which connects to the PC via USB ports. All three types perform the same function except for size and portability.

Standard Type

This type of PSU is built into the chassis of the laptop. It is very compact and lightweight. However, it does not allow users to upgrade parts individually. Instead, the entire unit needs to be replaced if anything goes wrong.

Modular Type

These PSUs consist of several smaller modules that can be removed and replaced separately. Modules include the power brick, fan, heatsink, and connectors. Users can replace individual components to improve performance or fix problems. Some models also contain additional features such as LED lights and fans.

External Type

This type of PSU is designed to attach to the outside of the case. It is larger than the previous two types and requires special tools to install. External PSUs are generally more powerful than internal ones due to the fact that they draw more power.

The Importance of Purchasing a Quality Laptop Power Supply

Laptops require a lot of electricity to run. Without proper power supplies, laptops could be damaged due to overheating. Overheated components can result in permanent damage to the motherboard. Therefore, it is very important to ensure that you purchase a high quality laptop power supply. There are many different types of power supplies available today. However, there are three main factors which determine whether or not a power supply is suitable for your needs.

Power Source Type

There are two main types of power sources; AC adapters and DC (direct current) batteries. Both types of power source are required depending on the type of laptop being powered. For example, most laptops require both an AC adapter and battery pack. Some laptops however, only require either an AC adapter or a battery pack.

Voltage Rating

This refers to the amount of voltage needed to operate the laptop. Most laptops require 12 volts while others require 24 volts. The higher the number, the greater the capacity of the power supply. As mentioned above, some laptops only require a single power source. Therefore, it is essential to check the specifications of the laptop before making a decision regarding its power requirements.


Most laptops are designed to be portable. Therefore, size is extremely important. Smaller power supplies are generally lighter and easier to carry around. However, larger power supplies are able to handle heavier loads and therefore are more powerful. Therefore, it is recommended that you purchase a power supply which has sufficient wattage to meet the demands of your laptop.


Finally, it is always advisable to purchase a power supply which comes with a warranty. This ensures that you receive support if anything goes wrong with the unit. Furthermore, warranties cover replacement costs if the product fails within the specified period of time.

In conclusion, it is imperative to purchase a high quality power supply for your laptop. Not only does this ensure that your laptop runs safely, but it also saves money in the long term. Remember, no matter what kind of power supply you decide upon, it must match the specifications of your laptop.

Affiliate marketing is a popular way to earn extra income online. Many affiliate programs pay commissions ranging from 10% – 50%. The commission depends on the program and the merchant who pays the affiliates. Here are five ways

Features To Look For When Buying A Laptop Power Supply

The most common type of power supply found in laptops today is called “wall wart”. Wall warts are designed to be plugged into a wall socket and connected directly to the motherboard via a standard USB cable. Most computers sold today include a built-in battery charger which uses the same kind of power supply. However, there are many advantages to using a dedicated power supply rather than relying on the internal battery charger.

Power supplies are generally smaller and lighter than batteries.

They require no maintenance and are very reliable.

Most models allow you to select different voltages (12V, 24V, 48V) depending upon the needs of your particular application.

Some power supplies can handle higher amperage loads than others.

Many modern power supplies incorporate safety features such as surge suppression circuitry and fuses.

There are several types of power supplies available including AC/DC adapters, DC/AC inverters, and DC/DC converters.

All power supplies must meet certain standards set forth by UL, CSA, TUV, etc.

Laptops typically run cooler when powered by a dedicated power supply.

In addition to being able to charge your laptop while running on its own power source, a power supply can also be used to recharge the battery.

Finally, a power supply can be purchased separately and added to your existing laptop.

How Do I Know Which Type Of Power Supply My Laptop Needs?

To determine whether or not you need a power supply, check the specifications of your current laptop. If your laptop has a built-in battery charger, chances are it already includes a power supply. Otherwise, consult the manual provided with your laptop to see if it lists a recommended power supply. If it does not list a specific power supply, contact the manufacturer for further information.
