2. Add up the power ratings: Sum up the power ratings of all the devices connected to the power strip. This will give you the total power consumption of the devices in the power strip.

3. Convert wattage to kilowatts: If necessary, convert the total power consumption from watts to kilowatts by dividing by 1000. For example, if the total power consumption is 2000 watts, the equivalent in kilowatts would be 2 kW (2000 watts ÷ 1000).

4. Estimate the usage duration: Determine the average duration of time that the devices plugged into the power strip are active or in use. This could be daily, weekly, or monthly usage. For example, if the devices are used for an average of 3 hours per day, multiply the total power consumption by 3 (in kilowatt-hours) to estimate daily consumption.

5. Calculate the power strip electricity consumption: Multiply the average daily consumption by the number of days in the selected duration. For instance, if the average daily consumption is 6 kWh and the selected duration is one month (30 days), the estimated power strip electricity consumption would be 180 kWh (6 kWh x 30 days).

It’s important to note that this calculation provides an estimation and may not account for variations in power usage or standby power consumption. Moreover, this calculation assumes that all devices connected to the power strip are active simultaneously. However, in reality, devices may not operate at their full power or may not be in use at the same time.
