Voltage — Montserrat 230V — Japan 100V

Most modern phones and chargers support dual voltage (100–240V), so they should work safely. High-power appliances may need a voltage converter—check each device label.

Device compatibility (phones)

Phones almost always support 100–240V. Because the voltage difference is large, check high-power items (hair dryers, etc.) for a voltage converter.

You may need a voltage converter for some devices, especially high-power ones that are not dual-voltage. Check each device label.
