Do you know how many watts your laptop charger uses? It’s an important question, especially if you’re trying to save energy. Some laptop chargers use more watts than others, and if you’re not careful, you could use more electricity than you need to.
In this blog post, we will discuss how many watts a laptop charger use, and we will also discuss some tips on how to reduce the amount of energy your laptop charger consumes.
In this article, we will discuss the watts that we will measure. . The rate of energy transfer is measured by the power unit known as the watt. A joule per second is equal to one watt. Laptop chargers are typically rated in watts, and the higher the wattage, the more power the charger can provide.
Most laptop chargers have a wattage between 45 and 65 watts. Some chargers may be higher or lower, but this is the most common range. But more advanced ones – like gaming laptops and such – can go up to 180 Watts per hour.
The wattage of your charger will determine how much power your laptop will use when it is plugged in and charged.
How to find out how many Watts a laptop uses when charging?
Your laptop’s charger is one of the essential components regarding how long your battery will last and how well your computer will perform.
The first way is to check the specs of your charger. Most chargers will have this information listed on them somewhere. If you can’t find it on the charger itself, you can usually find it on the manufacturer’s website.
Another way to find it is to use a power meter. A power meter is a tool that measures the electricity we use. You can buy a power meter or download a Power Meter app for your smartphone.
To find out the values for your particular laptop model, look at your charger and see the output (it will probably be the only number followed by a W, which is Watts).
Remember that the time your battery will last on a charge will vary depending on how you use your laptop. You can expect the battery to drain more quickly if you use it for heavy gaming or video editing.
Conversely, The battery should last longer if you only use your laptop for light tasks like web browsing or word processing.
How much power does a laptop use per hour?
Here are some of the other most significant factors that impact the actual power consumption of your laptop:
The processor: More powerful processors tend to use more power.
Screen size and resolution: A larger screen or higher resolution will need more Watts to run. So smaller laptops use less energy.
Battery capacity: A laptop with a larger battery usually consumes more power than a smaller one.
Internal components: If your laptop has a dedicated Graphics Card (and is also using it), it will consume more power. Other internal components, such as Multiple hard drives, optical drives, and RAM, SDDs, will also increase power consumption.
External peripherals: Anything extra that you have connected to your laptop and doesn’t have a power source will increase your laptop’s power consumption: This includes external monitors, USB devices, a mouse, an external keyboard, and a gaming controller; there are lots of options here.

Can I use a lower-wattage charger for my laptop?
How to Check the Laptop Power Consumption
You can first search for “Task Manager” with a right-click on the taskbar. Your apps’ features and how they work on your computer are listed here.
The task manager also details the amount of space in the app or software’s CPU. The only downside to this is you will need a clearer picture of power usage.
The sign of power usage is represented by “very low,” “low,” “high,” and “very high.”
Another way to determine how much power your laptop uses is to check your battery use. You’ll be able to get an approximate idea of how much battery life your apps and software consume.
Ways to Determine Your Laptop’s Power Consumption.
A power consumption calculator is one of the most reliable ways to determine how much power your laptop uses. To calculate your laptop’s power consumption, take the voltage (V) listed on the charger’s label and divide it by the current (A) required to charge your laptop.
This will give you power in watts (W). This formula allows you to figure out how much energy your laptop uses. You get a clear picture of the watts that are being used.
Another way to Check Your Laptop’s Manual or Specifications: Many laptop manufacturers list the wattage requirements of their models in product manuals, user guides, or on the manufacturer’s website.
Use a Wattmeter: If you don’t have access to this information, you can use a wattmeter to measure the power consumption of your charger.
This device will measure the electricity your laptop’s charger uses and tell you how many watts it requires to charge.
The wrong power supply can damage a laptop.
Yes! It will be ideal if you avoid charging a laptop with a charger with a different voltage than your laptop. This is because a high voltage may damage your computer permanently. This is typically affected by too high voltage. But using a charger with a high current will protect your computer. A low current rating charger might fry the power supply, but not the laptop.
How many watts does it take to charge a laptop USB-C?
The maximum charge speed for almost all USB-C charging PCs is 60 watts. But the 15-inch MacBook Pro has a full charging power of 87 watts. However, the 14-inch model’s maximum power in 2021 and 2019 is 96 watts, respectively. I am making them the most noteworthy exceptions.
How to minimize the energy laptop charger consumes
Laptop chargers are one of the most common electronic devices in use today. You can take a few steps to reduce the energy consumption of your laptop charger.
Use Wi-Fi carefully: Wi-Fi enabled on your laptop can significantly increase the energy consumed. When not in use, turn off your Wi-Fi so your charger can work less hard.
Turn down your screen’s brightness: The laptop’s screen is one of its primary energy consumers. Turn it down if you don’t need the intelligence so your battery lasts longer. A bright screen indicates that your laptop is using more power. Additionally, you’ll consume less energy when charging your laptop.
Do not do processor-intensive tasks: Tasks like gaming and video streaming require a lot of power from the battery, but if you are doing everyday work, you do not need to use so much energy. This will help reduce the number of watts being used while charging.
Turn on power saving mode: You can turn on power saving mode. This will help reduce energy usage and decrease the energy your laptop charger needs to use. Power saving mode allows adjusting settings like processor clock speed, dimming the display, and turning off unused functions when not in use.
Switch off certain apps at specific times: Many apps can run unnecessarily in the background. These make your laptop work harder and, as a result, consume more electricity. This will help reduce the amount of energy your laptop charger is using.
Reduce heat: Heat is a significant energy drain on your laptop charger. If you can keep your laptop cooler, it will reduce the watts used to charge it.
Keep the vents clear, and avoid placing the laptop in direct sunlight or hot areas. This will decrease the amount of electricity essential to cool the computer.
Switch off and unplug: Open the power adaptor and switch your laptop off when fully charged. Off mode can use more electricity than Sleep mode per day due to the extended period that the computer is in that mode. So, to save energy, remember to unplug. This will help reduce the amount of energy the charger uses when not in use.
These few tips have been tried, tested, and proven very efficient. They will go a long way to ensure you preserve your battery life and save on electricity bills.
As you can see, even though your laptop’s power consumption varies depending on the model, peripherals you are using, and what you’re doing with your computer, it will still use very little energy overall.
Different laptops support different power inputs. A laptop charger uses between 45 too 65 watts of power. The average is about 45 watts.
If you want to save power, it is not worth unplugging your charger when your laptop is not in use.
Can I charge my laptop twice a day?
Yes, you can charge your laptop twice a day. However, letting the battery drain completely before recharging is best. This will make your battery last longer.
Is a 45W charger good for a laptop?
45W with USB Power Delivery PPS support is futureproofed, suitable for tablets, and even reasonable laptop charging speeds.
Can I charge my HP laptop with another charger Of the same voltage?
If the voltage is the same, the current the lower supply can handle is more than the laptop needs, the polarity matches, and the power supply is of merchantable quality, it will be fine.
