Maximum Power Consumption

Power consumption measured in watts (usually in milliwatt, mW) is the correct term for low power applications but all too often the current consumption measured in ampere (usually milliamperes, mA) is used instead. As the power is just the operating voltage multiplied by the current, this is trivial for fixed voltage operations but becomes more tricky to estimate when using batteries that discharge and the voltage changes over time and loading conditions.

Maximum Power Consumption is the maximum electrical power consumed in normal operation of the product, dependent upon the Supply Voltage and any internal power saving modes of the product.
