Voltage by Country: Will My Device Work Abroad?

Voltage is the part travellers forget until something hums, heats, or fails. Check the destination voltage against your device's label before you plug anything in.

What is the Voltage by Country?

Choose a country and the tool shows its standard mains voltage and frequency. Most of the world runs near 230 volts at 50 hertz, while North America and Japan run near 100 to 120 volts. This is a major-country reference — verify before you travel, especially for heating devices and older equipment.

How to use it

  1. Choose a country.
  2. Click Show Voltage.
  3. Compare it with your device's rated voltage before plugging in.

Worked example

The United Kingdom uses 230 volts at 50 hertz.

What happens if I plug a 230 V device into 120 V?

It usually runs weakly or not at all. The dangerous direction is the reverse: a 120 V device on 230 V can overheat or fail.

Frequently asked questions

Do phone chargers handle different voltages?

Most modern chargers are dual-voltage (100–240 V) and only need a plug adapter — but always read the label.

Should I verify before travelling?

Yes. This is a major-country reference, and local supply can vary.
