If this product has an off mode which still consumes a small amount of power, then to completely stop product power consumption,
disconnect the power cord from the wall outlet.
Total energy usage
It is sometimes helpful to calculate the total product energy usage. Since power consumption claims are provided in power units of Watts,
the power consumption should be multiplied by the time the product spends in each mode in order to calculate energy usage. The total
product energy usage is the sum of each mode's energy usage.
