(Consider a step up Transformer).
Let the input voltage be "V".
Input current be " I".
Transformation ratio be k = 2.
So here the input voltage V = 2*V" (output).
But output current I = 1/2 I.
So, the power would be P = V*I (Consider constant power factor).

A step-up transformer steps up the "voltage" not power.
