How Much Power Does A Laptop Use Per Hour

A 15-inch laptop consumes approximately 12 volts or 60 watts per hour.

How much power does a laptop use per hour. An average desktop computer uses between 60 and 300 watts. Typically the amount of electricity a computer uses is between 65 watts and 250 watts. Determining the amount of electricity a computer uses can be a somewhat complicated task since it depends on what type of equipment a person has and what applications he is running.

If its idling on desktop the laptop will use 5-10W. LCD monitors takes twice. Most computers are built to use up to 400 kilowatts of electricity per hour but they usually use less than that.

The power consumption of a laptop depends on the screen size typically you will find power consumption as low as 20 watts and up to 100 watts when running off the battery. Desktop monitors during the sleep mode use between 5 to 10 watts of power while the laptop monitor uses about 2 watts. A desktop uses an average of 200 Whour when it is being used loudspeakers and printer included.

If its running a browser watching movies and general usage including running most desktop applications the laptop will use 10-15W. The average electricity cost in the US is 13 cents per kWh. A computer that is on for eight hours a day uses almost 600 kWh and emits 175 kg of CO 2 per year.

An old laptop takes 25W total when running. This is the average estimation we took according to the Energy Department. It is very difficult to know exactly how much computers use on average because there are so many different hardware configurations.

The laptops whose sizes range from 12 to 15 inches usually use around 60 watts per hour while the laptops that have a 17-inch or above screen consume 70 watts or higher on average. Roughly 30-70 watts are used with that figure varying from model to model as some people will opt for specific features meant to enable certain draining functions. Since the average cost of electricity is around 28 centsKWh here in San Diego my weekly cost is roughly.
