hi, i really want to know if a transformer or power supply of 250v 7.5a can run a pedestal fan. I checked the plug for the power outlet and it says 250v 7.5a. is this right? i just want to power the fan without the power outlet. if this is right could anyone tell me where i can purchase a power supply or transformer and if i can go to 10 amps instead of 7.5. Ive been searching but have not found anything suitable. thanks
