Why You Need a Power Converter for International Travel

Power voltage and frequency differ across the world. In North America and parts of South America, the standard is usually 120 volts and 60 hertz (Hz). However, in Europe, Asia, Africa, and many other regions, the standard is typically 230 volts and 50 Hz.

When you travel internationally, your electronic devices might not be compatible with the local power standards. A voltage converter helps by adjusting the voltage so your devices can safely be used abroad.

For example, airplanes use 400 Hz power internally, which differs from the typical 50 Hz or 60 Hz used on the ground. Specialized converters adapt this for various needs, whether powering the airplane on the ground or providing in-flight power for passengers.

Consumer electronics often come with an AC adapter to convert high-voltage AC current from the wall outlet into the low-voltage DC current needed by the device. When traveling between countries with different voltage standards, a voltage converter (often called a "travel converter") is essential to protect your devices. However, keep in mind that simple "adapters" only change the shape of the plug and do not adjust the voltage or frequency.
