How do I choose the right transformer?

On the back of your appliance, you should be able to find a label describing the specification of it. You should see a label describing the Wattage (W) or the Amperage (A) of the appliance.

Example: If your appliance consumes 80 watts then you need a VC-100 transformer (100 watts capacity) or higher.

If you want to operate 2 appliances on one transformer. One of them consumes 300 watts and the other 130 watts then you would need a VC-500 (500 watts capacity) or higher.
