Undoubtedly, technology has embedded its roots deeply into Humankind and people have become dependent on it. Not only is it evolving further to help the growth of civilization but it is also easing people’s lives.

As you all know, this pandemic has gravely affected everyone globally. Making their in-person contact as limited as possible and at that peak, technology played a significant role in stabilizing the economy and growth.

People turned towards online platforms for running their businesses and continuing their education. Since then, the demand for Laptops has reached its peak. Where having a personal laptop or PC became a basic necessity.

Additionally, what concerns the people at times is how many watts does a laptop charger uses per hour? Nowadays, electricity is nowhere cheap, and people’s concern regarding power consumption is genuine. Don’t worry! You’ll be surprised to know that the numbers are meager.

Various Types of Laptops and How many Watts does a Laptop Charger Use?

This might seem a simple question, but there are several underlying factors contributing to the main cause in reality. Usually, it’s known that a laptop tends to use around 60 – 90 watts per hour as per its charging.

But other factors affect the charging, like the model and type of laptop, etc. Moreover, based on power consumption, there are several types of laptops.

How many Watts does a Laptop Charger Use

Gaming Laptop

A Gaming Laptop or high-end laptop generally has heavy-duty specifications and is observed to be highly power-consuming. It not only carries top-notch specifications like high core count but also carries a significantly dedicated graphic card.

That, in turn, adds up the count to its power consumption. Moreover, to enhance the laptop’s aesthetics, it has plenty of RGB features like a keyboard with a backlight. That, in turn, consumes more energy than the normal ones.

Usually, such laptops have type C power charging adaptors, and such adaptors support lighting charging and boost their capabilities to charge the batteries as fastly as possible. Hence, depending upon its heavy-duty specification, its power requirement for charging is somewhere around 135 – 160 Watts.

Standard Laptop

Everyday laptops are commonly used in offices, homes, businesses, and schools. They are very portable as they are lightweight and carry consumer standard hardware specifications.

Unlike gaming laptops, they don’t have a backlighting keyboard, a specifically designed ventilation system, or a dedicated graphic card. Thus, its power consumption is much more budget-friendly.

Usually, such laptops have Type C or Round pin Jack power connectors for charging. Which in turn helps in powering up their lithium batteries. However, they often lack fast charging. But they still have a higher charging capacity due to bigger batteries lasting longer than a gaming laptop. Thus, making them more portable for daily use. Such laptops usually consume around 60 – 80 Watts of power through a charging adaptor.

Workstation Laptops (e.g., Dell Precision, Lenovo ThinkPad P Series):

  • Workstation laptops designed for professional tasks often come with high-wattage chargers.
  • Charger wattages can exceed 130W.
  • Average power consumption: 130W to 160W.

Apple MacBook

If you are a MacBook user, then a typical 13 inches MacBook pro consumes around 61 watts of power as given in the charger. Whereas 15 inches, MacBook consumes around 87 watts per hour.

Ultrabooks and Light Laptops (e.g., Dell XPS 13):

  • These laptops often come with lower wattage chargers, typically in the range of 30W to 65W.
  • Average power consumption: 40W to 50W.

Factors Affecting the Power Consumption of Laptops

The laptops are built so that each component tends to work as energy-efficiently as possible. But at the same time, it has many large consumers and functions. Generally, the Display and the Processor serve to be the large consumers. Additionally, the main components of power consumption include.

●            Random Acess Memory (RAM)

●            Graphics Card

●            SSD/ Hard Disk

●            Fan

●            Touchpad

●            WLAN Module

Moreover, if you use the latest model laptop with a multi-core processor heavily, its power consumption will rise to 60 Watts or more. Therefore, the graphics card is the major factor. If one is installed in your laptop, its power consumption will be significantly higher than normal. As the graphics aren’t just calculated through the main processor. However, Graphic Cards are only built into Gaming or High-end Laptops.

here’s the average power consumption for different laptop charger wattages:

  1. Ultrabooks: 40-50W
  2. Standard Laptops: 70-80W
  3. Gaming Laptops: 120-150W
  4. Workstation Laptops: 130-160W

A laptop charger works to provide electrical power to a laptop’s battery and components. Here’s a simplified explanation of how a laptop charger works:

  1. Plug Connection: The charger has a plug that you connect to a standard electrical outlet or power source. This source typically provides alternating current (AC) electricity.
  2. Transformer: Inside the charger, there is a transformer that converts the high-voltage AC power from the wall outlet into a lower-voltage direct current (DC) suitable for your laptop. This conversion reduces the voltage to a safe level for the laptop’s internal components.
  3. Rectifier: After converting the voltage to DC, a rectifier circuit ensures that the current flows in a single direction, preventing any oscillation between positive and negative voltage.
  4. Voltage Regulation: Many laptop chargers include voltage regulation circuits to maintain a steady and precise voltage output, typically around 19 volts for laptops. This ensures that the laptop receives the correct voltage it needs to operate.
  5. Connector: The charger has a connector or plug at the other end that fits into your laptop’s power input port. This connector transfers the DC power to the laptop.
  6. Charging the Battery: When you plug the charger into your laptop, it provides power to charge the laptop’s battery. At the same time, it supplies power to the laptop’s internal components, allowing you to use it even when the battery is low or removed.
  7. Battery Management: The laptop’s internal charging circuitry manages the battery charging process. It ensures that the battery is charged safely and prevents overcharging, which could damage the battery.
  8. Powering the Laptop: While connected to the charger, the laptop can draw power directly from the charger, bypassing the battery. This is especially useful when you need to use your laptop for extended periods without relying on the battery.
  9. LED Indicator: Many laptop chargers have LED indicators to show whether they are actively charging the laptop. This can help you confirm that the charger is functioning correctly.
  10. Safety Features: Modern chargers often include safety features like overcurrent protection, overvoltage protection, and thermal protection to prevent damage to the laptop and ensure safe operation.

Overall, a laptop charger converts AC power from an electrical outlet into the appropriate DC voltage for your laptop and charges the laptop’s battery while providing power to the device itself, allowing you to use it both plugged in and on battery power.

Conclusion How many Watts does a Laptop Charger Use

All in all, your Laptop Charger power consumption varies depending upon the model, peripherals you are using, and how you are using your laptop. It will still use little energy overall. It depends on the number of watts its adaptor supports.

But the count can increase as the watt requirement increases. Nonetheless, no matter how many watts your laptop is taking, you should stay careful and try to minimize the load on the battery and let it charge properly.

If you follow this tip, it will help you retain your laptop’s long life, and you’ll be able to have a long-lasting battery as well.
