A smartphone might produce 1 watt of power. A voltage of 1 volt producing 1 ampere of current over 1 second is 1 watt of power. (Did I do that right?)
Or a kid pushing a toy block might produce 1 watt of power. Accelerating one kilogram one meter-per-second every second, moving it one meter in the direction of force, in one second — that’s also 1 watt of power.
These come from different definitions of power. In what sense does it make sense to say it is the "same" amount of power? Are they convertible or comparable?
