How Many Watts Does a Laptop Use When Charging?
The battery charging is the main factor that you prefer when buying. All laptops are not the same and do not consume equal energy or watts during charging.
A 15-inch screen approximately needs 60 watts an hour, equivalent of 0.06kWh when charging. It also depends on different models and types of PC. There are variations in the watts consumption of different manufacturers.
Laptop model and type
There are loads of brands and various companies developing gadgets every year. With the latest technology, they build machines with better achievement and functions.
So power consumption is determined by the different types of devices. It also depends on the work that you are doing on the processor.

If you have a high end or gaming computer, it will consume more than 135 watts per hour, and few gaming processors use 180 watts per hour.
A few types of gadgets use 100 watts per hour; these kinds of processors becomes hot and require to cool down. A 13 inches MacBook use 61 watts, and 15 inches Macbook uses 87 watts per hour.
Different elements affect charging and Watts consumption
LCD size
The LCD size of each PC affects power consumption. It is a significant factor that affects power supply during charging.
The big size screen uses high volts per hour to charge, and the small screen size uses fewer Volts per hour.
The gadget with 12 to 15 inches screen size use about 60 watts in one hour. A gadget that has a 17 inches LCD require almost 70 watts or higher in 60 minutes.
The computer with 20 to 24″ LCD requires approximately 80 to 90 watts per hour. An old notebook with 17 to 19 inches screen size use around 100 watts in 60 minutes. Sony Vaio laptops use different power consumption as well.
Central Processing Unit
As it named CPY is the central or main part of the computer. And it is responsible for all the functions, applications, and operating systems that you use.
There are many functions of different model devices that help to increase the performance of the processing unit. When your CPU performance is fast and right, then it consumes more energy or gets battery lifeless.
The battery receives pooped when the processing unit consumes more energy to perform tasks. CPU and power consumption has a positive correlation. The higher the processing unit, the greater the consuming watts while charging.
Laptop Charger
The processor watts consumption during the process also depends on the charger. Different gadgets have their tools and devices for this purpose.
A 17-inch processor uses a 90 watts charger, and 15 inch PC size consumes 65 watts adapter to charge it and an a15.6 inches processor uses 70 watts adapter for this purpose.
If electricity supplies properly and the charger works accurately, a processor uses approximately 60 to 90 WH.
