🔌 Device Compatibility
Thailand uses 220V electricity, which is significantly higher than the 120V standard used in North America. This means you need to be careful about which devices you plug in.
Most modern electronic devices (smartphones, tablets, laptop chargers, camera chargers) are designed to work with both 110-240V, making them safe to use in Thailand with just a plug adapter. Look for "Input: 100-240V" on your device's label or power adapter.
High-Power Devices Need Converters
Hair dryers, curling irons, electric shavers, and small kitchen appliances designed for 110-120V will be damaged by Thailand's 220V supply. You'll need a voltage converter or step-down transformer for these devices.
