There are products called Step Up transformers/Step Down (Voltage Converters) that can be used. We use these For our 220VAC Australian manufactured lasers when we need to run them in a Dr.'s office that only has US 110VAC.
Info from a website
Electrical voltage in USA is 110 voltwhereas; the voltage in most of the foreign countries is 220V to 240 volt. A voltage converter / transformer, also known as power converter are usedto convert electricity coming out of the wall to match the voltage of yourdevice. These Voltage transformers or converters can be used safely withRefrigerators, Microwaves, Juicers, Blenders, Coffee makers, Power Tools,Stereo Systems, TV's, Video Games, DVDs, Hair dryers, Chargers, computersand other electronics when travelling abroad..
Remember to leave at least a 100-percent margin for power surges/spikewhen buying a transformer. Some items, such as Televisions, computermonitors spike when you turn them on. For these products you need to buy avoltage converter transformer that is at least 3 times the items capacity.Power tools, laser printers and heating appliances like coffee makers,toasters, microwaves, Halogen, Fluorescent bulbs you must leave a marginof 3-4 times.
Voltage transformers are made to convert single phase 110 or 220 volt.American 220 Volt consists of 2 phase of 110 Volt and European 220 Voltconsists of 1 phase of 220 volt.
Volts x Amps = Watts (i.e. 110V x 0.5 AMPS = 55W). Please make sure not torun any appliance with higher wattage then voltage transformer's wattage.This might damage both: your appliance and the transformer!
I hope this helps.
