Why Watts differ when voltage does for same Ampere

Can you tell me, when Amps is a measure of how many electrons pass through a circuit per second, and a different voltage can be used to create the same Amps in a circuit, why does P = v*i, when the number of electrons passing through the circuit is the same?

The "different voltage for the same amps" requires a different load resistor connected to the volt source which in turn means you have to "push harder" on the electrons to get the same current to flow.
This is a super dumbed down explanation but ultimately requires more power leading to P=v*i. You can probably find a much better discussion of volts, amps, power and ohms laws in the Circuit Lab Textbook.
