Laptops are almost in every house these days, and almost everyone knows how to use them. But, just using them is not enough. You must understand your laptop specs and how many watts does a laptop use? Because this will help you when you travel. For instance, you can buy a perfect charging cable if your original one expires somehow.
And, if your laptop is not fully charged and you are on one day’s vacation, you can figure out how long the battery will last. Even though many people don’t bother to know more about it, it is always crucial to know about the battery watts. Today, we will see what the laptop’s charging voltage is and how long can your laptop battery last?
How many watts does a laptop use on average?
On average laptops use between 20-100 watts per hour for charging, while some take around 180 watts. The watts are never the same for all laptops as they depend on the type of usage you do.
So, if your laptop uses more watts, you cannot blame the charger as it is all about your specs and usage. From usage, I mean, your primary usage like video watching, music playing, doing some use of Word, etc.
This type of usage doesn’t take a lot of power from the specs, and they take 20-100 voltage.
However, if you run heavy programs, do some ethical hacking, or play high-end games, the specs will take a lot to perform. So, I will discuss the specs that affect the watts of the laptop. Check below.

Adapters for the laptops
The bigger your laptop is, the higher watts it will take to charge the laptop. And, remember, if you upgrade the laptop to higher specs, it will run high-end specs and take more power. And, we already know that high-end specs, especially in gaming laptops, take more power and drain the battery faster. So, with such specs, you can expect the battery to take 180 watts or even a little more. So, that’s how the system works.
High-end CPU
Now, we talked about the adapters taking the watts depending on the usage of the laptop. However, if we talk about the CPU, the system is the opposite here. You keep upgrading the CPU, and note that the battery will stay. So, the higher the CPU is, the lower watts it will take.
You will need to upgrade the CPU for heavy-duty tasks like professional editing, streaming for the whole day, or running heavy-duty programs. You can go for a better graphics card and a processor that gives a lag-free performance. And with this extreme usage, the laptop will take around 120 watts for charging.
Note: The laptop charging also depends on the brand models, so you can not always blame the specs. The battery watts will work according to that. I’m talking about laptops like HP and Acer that don’t drain their charging quickly.

Graphics card for your laptop
A graphics card plays a vital role in every laptop’s display; I’m counting the PC in. So, if you have to do tasks like spreadsheets or watch YouTube or Netflix on laptops, you can manage with the graphics card your system already has.
However, if you think of handling some high-end tasks, running CAD programs, and doing professional editing, go for a specific graphics card. You can opt for what you find suitable for your use. However, I can say that NVIDIA GeForce RTX 2060 is the best card in the system.
Now, please note that it won’t take power as the CPU once you upgrade the graphics card. Instead, it will take more power than before, and your laptop battery will drain sooner.
The display matters a lot.
Now, even if you know it or not, the display size plays a crucial role in the watts usage the power cable takes. So, if your display is 16 inches, the laptop will take up to Fifty watts for charging per hour. And, if your laptop is 17 inches or so, the laptop will take 100 watts per hour for charging. So, yeah, if this information was new for you, you can figure out the watts from your screen size quickly now.
How many watts to charge a laptop does the charger take?
A laptop charger typically takes 20-100 watts or 50 watts to charge the laptop. This watts consumption is of normal usage on laptops. And, if the laptop has high-end specs, it may take up to 150 watts to charge. And as I stated above, the laptop specs differ from laptop to laptop depending on the brand.
So, if you want a rough estimate, you can check the charging adapter of the laptop to guess what is maximum watt capacity your system can take. That’s how you can easily take the idea.
How many watts does a gaming laptop use?
Any high-end gaming laptop uses 130-185 watts, and any high-end gaming PC takes 300-750 watts. Now, I have a better example to give you. If we see one of the best laptop brands like Acer Predator Helios 300, its charger tells us that it takes 180 watts of charging. That clearly defines that it takes 180 watts per hour to charge the laptop. Also, we know how good Helios 300 is for streaming, gaming, and regular usage like spreadsheets, etc.
So, you cannot question the specs of the Helios 300 laptop. Now, here is also a question which systems take more watts? Whether it is a PC or laptop. So, the answer is below.
If you still have any confusion, check the video below:
How much power does the gaming laptop use per year?
If you want to take the annual estimate of the PC and the gaming laptop, a PC takes 6 times more power than a laptop annually. Because a laptop will take 300-500 watts in an hour, it will make 1400KWH annually, making it six times more than the gaming laptop. So, yeah, laptops are the best choice.
Conclusion
I’ve tried to explain to you how many watts does a laptop use? So, whenever you feel confused about the laptop watts, check the adapter and read the maximum watts given on the system.
