When people purchase laptops, they usually ignore some important factors that need some attention and have a significant role in the laptop’s overall performance. And one of the most important factors is the energy a laptop consumes. So, if you are planning to get a new laptop, you must consider how much Watts it consumes while using.

If you are wondering and want to know the power in figures, read this complete informational article to get all the details about energy consumption. Let’s move ahead without further ado and explore How many watts does a laptop use when charging?

Energy Consumption in Laptops 

When you go to the market to purchase a laptop, then you find plenty of laptop brands with a wide range of different specifications, but if you want a typical and straightforward answer to this question that How many watts does a laptop use when charging then the answer is 60 Watts per hours for a 15 inches laptop.

But you cannot use this answer as an average answer because there are many factors on which energy consumption depends. The most common factor among all is the hardware connection because the more hardware you connect with your laptop, the more it will consume power. And it is also true that different types of laptops consume different power. 

Let’s look at the energy consumption of some important types of laptops!

Energy Consumption of a Gaming Laptop 

Gaming laptops have the heart of many customers, especially the youth, because they are the best part-time partners and fulfill all their gaming needs and help them pursue their careers as a gamer.

Still, it is a fact that a gaming laptop is a complex assembly of different types of components that are enclosed in a single unit, and that is why they consume a lot of power.
