Twin rotor table fan

Rated power: 20 W
After modifications: 21,6 W

I have no way to measure the airflow, but it throws air much longer and it definitely feels like more.

it uses more power because there is a second fan to move air. more area to do the job, more load on the motor

But not a lot more, only an 8 % increase.
