If your grounded appliance is multi-voltage (120/240 or 100-240 volts) you only need a grounded adapter plug.
If your grounded appliance is 120 volts only, you need a grounded transformer to convert the voltage and a grounded adapter plug to modify the outlet.
Please note: Adapter plugs do NOT convert electricity
