How to Test a Voltage Converter Before You Travel

When traveling abroad from the United States, you will most likely encounter electrical systems that run 220 to 240 volts. Compare this to the US electrical system at 110 to 130 volts. To use an electrical device such as a computer, camera charger or MP3 player on the higher-voltage system you will need a voltage converter. These devices are sold for the purpose but should be tested for effectiveness before you travel. You do not want to lose an expensive electronic device because it receives too much voltage from the converter.

- 1
  Select the setting on the step-up transformer for the voltage of the location you will be visiting, which will likely be from 220 to 240. If you cannot figure out how to do this by looking at the transformer, consult the user manual. Plug the transformer into the wall outlet and switch it on.

  Plug the voltage converter into the step-up transformer. You may have to use a plug adapter to do this. Now the travel converter is receiving 220 to 240 volts of electricity.
- 3
  Observe the voltage converter for signs of overheating. If it seems to be satisfactory, plug your electrical device into the converter. Turn the electronic device to its fullest setting for a few minutes and again observe the voltage converter for signs of overheating.

  Note if the converter is exceedingly warm or if there is a smell of burning plastic. If either of these conditions exist, the voltage converter is defective. Unplug the converter from the transformer immediately and let it cool. Do not use it.
