According to the United States Department of Energy’s most recent laptop power consumption estimate, a standard laptop charger uses 50 watts of electricity, equal to 5-kilowatt hours. Using an average, a WH implies that if a laptops is used for eight hours a day, it would cost 5p a day to keep it running.
How many watts do I need for my laptop?
There is no single answer to how many watts a laptop uses. While most need anywhere between 20 and 100 watts per hour, this can increase to 180 watts per hour for some laptops. These variations often reflect the reason for the laptop’s use.
