Steps
1. Look for the wattage of your laptop charger.
2. Find out how many watts your laptop uses.
3. Use a simple equation to calculate the power usage of your charger.
Most laptop chargers have a wattage between 44 and 60 watts. To find out how many watts your particular charger uses, look at the label on the charger or the manufacturer’s website.
The power usage of your laptop charger can be calculated by simply dividing the wattage of the charger by the number of watts your laptop uses.
For example, if your laptop uses 50 watts and your charger has a wattage of 60, then the power usage of your charger is 60/50, or 1.2.
In general, it is safe to assume that your laptop charger uses about 1 watt of power for every hour that it is plugged in.
So, if you use your laptop for 3 hours per day and your charger has a wattage of 60 watts, then your total power usage would be 60*3, or 180 watt-hours per day.
How Much Power Does A Laptop Charger Use?
A laptop charger typically uses between 15 and 20 volts of direct current (DC) to charge a laptop battery.
The power required to charge a laptop battery depends on the size of the battery, as well as the charging method used. Some older laptops may require up to 90 watts of power, while newer models may only need 60 watts.
Does The Type Of Laptop Charger Take A Difference?
There are three main types of laptop chargers: universal, OEM (original equipment manufacturer), and aftermarket.
Aftermarket chargers are usually cheaper than OEM or universal ones, but they may not offer the same level of quality. In terms of power usage, all three types of chargers should be similar.
How To Reduce The Amount Of Power Your Laptop Charger Uses?
