How to Identify Dual Voltage Appliances

When you travel overseas, you'll probably want to bring some electronic gear with you. For example, you may want to bring your laptop, a hand-held game console or even your hairdryer. Before you travel, you'll want to purchase some adapters so that you can plug in your electronics. You may need a power converter. This depends on whether or not your electronics are dual voltage. If they are, you can save the money on the converter.

  1. Look at the plug for your electronic device. Determine if the device contains any language about dual voltage.

  2. Look for a notation about input. When you find that line, determine the voltage the device will accept. If the input is 110V to 240V, your device is dual voltage. You can use a plug adapter, but do not need to use a power converter.

  3. Purchase a power converter if the device says 110V but does not mention 240V. Your device is not dual voltage.

  4. Contact your travel agent or a representative at your travel destination before you travel. Plug holes, shapes and sizes vary from country to country.

  5. Tip

    On a laptop, the input directions are sometimes on the bottom of the laptop instead of on the power adapter. If you cannot find the input on the adapter, keep looking.


    When you are overseas, don't leave the converter plugged in when you are not using it. Converters can overheat and may cause a fire if left for too long.
