Plug & Voltage Checker

Most modern electronics like phone chargers, laptops, and camera battery chargers are dual-voltage (labeled 100-240V) and only need a plug adapter. High-power devices like hair dryers, curling irons, and straighteners often require a voltage converter. Always check your device's label before plugging in.

Southeast Asia uses a mix of plug types. Thailand primarily uses types A, B, and C; Vietnam uses A, C, and D; Indonesia uses C and F; Singapore and Malaysia use the British type G. A universal travel adapter covering types A through G is recommended for multi-country trips in the region.

Plugging a 110-volt device into a 220-volt outlet without a converter will likely destroy the device instantly and may cause sparking, smoke, or fire. A 220-volt outlet delivers twice the voltage the device is designed to handle inside. Non-electronic items with heating elements and motors are the most vulnerable to this damage.

Japan is unique among major travel destinations in using a 100-volt standard. Most of the world uses either 110-120V like in North America or 220-240V common in Europe, Asia, and Australia. Japanese outlets use the two-prong type-A plug, similar to North America but without the third grounding pin.
