Power, is a scientific term that has specific denotative meaning. In a typical reference such as "high powered rifle" the information conveyed is that the rifle has a relatively long effective range. Power is basically a measure of energy delivered per a unit of time measured. A long trip through a resistive medium (air) drains energy from the bullet during its flight. A "high powered rifle" would be one which fires a round where the bullet retains sufficient energy at the end of a comparatively longer flight to impart an incapacitating degree of ballistic trauma.

Your edit does highlight what you mean well enough but the media often uses terms without a logical basis and frequently only for sensational effect.

I day to day I might remark about a "powerful" cup of coffee. There would be little chance of anyone inferring a scientific meaning from that remark.

Pardon the intrusion. Nice to have you here.
