That is an awesome idea!

Tried some cellular chargers, led is blinking but motor wont work
Yep, cell charger current is too low.
I doubt the Airwick has any voltage regulation built-in. But 3.3V is a common max voltage for microcontrollers, so it can probably
handle that voltage without a problem; and that opens up a few possibilities. Plus you'd get more motor torque too.
