Are some appliances already dual voltage?
Yes. Most modern electronic equipment including battery chargers, computers, printers, stereos, tape and CD players, VCR’s, etc. are built specifically for use across a wide range of power supplies such as 220 volts. However, you must still read the read all instructions and always check the appliance you plan to use for compatibility. Also, most common hair dryers, curling irons, steamer irons, regular irons, and beverage heaters can be found that will have a voltage selector switch. Multi-voltage appliances will not have the selector switch but will show the input voltage as 100-240V. Check the owner’s manual or the appliance to determine the input voltage and wattage.
