When you travel from a 110 volt country (like USA) with your 110 volt devices to a 220 volt country (like Europe, Africa Asia etc), You will need a Step Down Transformer or a Converter.
If you travel from a 220 volt country (Europe/Asia) to a 110 volt country like USA, you will need a Step Up Transformer or a Converter.
Also, there are Step UP/Down Transformers and converters available that work both as Step Up and Step Down. You will find a wide variety of Step Up/down Transformers and converters on our website www.voltage-converter-transformers.com. Ranging from 50 watt to 20,000 watts, these transformers enable the use of your electric devices anywhere in the world.
Remember to leave at least a 100% margin for power surges/spike when buying a transformer. Some items, such as televisions and computer monitors spike when you turn them on. For these products you need to buy a voltage converter transformer that is at least 3 times the items capacity. For power tools, laser printers and heating appliances like coffee makers, toasters, microwaves, lasers, halogen or fluorescent bulbs you must leave a margin of 4 times. It doesn't hurt to buy a transformer that is rated much higher than listed watts on your device.
