Q1:     What do I need to operate my US appliances overseas, and vice versa?

ANS:  Voltage Converter + Plug Adapter  (yes, you need both)

There is no worldwide standards for electricity voltage/Hz. You need a voltage converter to transform the voltage of the local electricity to the voltage level required by your appliances; otherwise you might damage your appliance or cause fire. All voltage converters run on AC electricity only.

Tere are no worldwide standards for the plug configuration. You need to get a plug adapter in order to plug your appliance into foreign electric outlets.

For more information about plug adapters, please refer to our Plug Adapter Country Chart.

Q2:     What does voltage converter (i.e., transformer) mean?

ANS: Voltage converters transform AC electricity between US voltage and European volt.

North America and some other countries operate on 110V/120V, AC 60Hz. Europe and most other countries operate on 220/240V, AC 50Hz. Voltage converters transform the voltage of the local electricity from 220/240V to 110/120V or vice versa, so your equipment can operate in different countries without being damaged.

Q3:     What does "Step Down" voltage converter / "Step Up" voltage converter mean?

ANS: Use Step Down voltage converters in Europe.  Use Step Up voltage converters in the US.  ..

A Step Down voltage converter transforms local electricity from 220/240 volt AC Down to 110/120 volt - so that you can  use US 110 volt appliances in Europe.

A Step Up voltage converter transforms local electricity from 110/120 volt AC Up to 220/240 volt - so that you can  use European 220 volt appliances in the US.

Q4:     How do you determine which Voltage Converter you need?

ANS:  By Wattage!

Find out the voltage (110 or 220 Volt AC) and the wattage rating (watts or amps) for you appliance. It should be written somewhere on the device or in the manual. If watts info is not present and only amps is shown, take the volts (input AC) and multiply that number by the amps to find watts.

Example:    Volts(AC input) x Amps(amperage) = Watts (Wattage)

110V x 0.3 Amps = 33 Watt 

Q5:     What is the buying guideline with regards to wattage?

ANS:  Buy a voltage converter with wattage higher than the wattage listed on your appliance.

You should always run your voltage converters at 17% ~ 80% of their rated wattage capacity - never exceed 80% if possible!  Please make sure not to run any appliance with wattage higher than the wattage of your voltage converter. This might damage both: your appliance and the voltage converter!

Q6:     Can I use several appliances at the same time on the same voltage converter / transformer?

ANS:  The key is the total Wattage.

As long as the total wattage of all appliances does NOT exceed the wattage capacity of your transformer/converter. If you want to run multiple appliances, run the transformer at 80% of its wattage to avoid damaging your appliances by power fluctuations.

Q7:     Are grounding and fuse useful or just waste of money?

ANS:  Grounding and fuses provides additional safety protection - they protect against accidental electrical shock and damage. Grounding is a crucial requirement for sensitive (and often expensive) appliances such as medical equipments.
