The Only Travel Adapter You’ll Need in Thailand
A bad travel adapter can ruin your trip. We don’t sell them, but we’ve researched the best one for Thailand—checking voltage, outlet types, speed, and safety. This one gets top marks:
If you’re already traveling or at your destination without a power adapter, no worries—you’ll probably be able to find one nearby. Still, bringing one from home just saves you the extra step and gives you one less thing to think about.
Visiting Thailand as part of a bigger trip? Many travelers also explore Cambodia and Vietnam. It’s a good idea to confirm plug types in advance.
Power Outlets in Thailand
In Thailand, they use Type A, B, C, and O power plugs and outlets.
Type A
Type A outlets have two flat prongs and no grounding pin.
Type B
Type B outlets have two flat prongs and a grounding pin. Type A plugs will also fit.
Type C
Type C outlets have two round prongs and no grounding pin. Type E and F plugs usually fit too, but grounded plugs will need an adapter.
Type O
Type O outlets have three round prongs in a triangular layout and are designed for high voltages. Type C plugs may sometimes fit, but it’s not recommended.
Do You Need a Voltage Converter?
Planning a trip to Thailand? The voltage there doesn’t match the 120V we use in the U.S., so you’ll probably need a voltage converter.
Always double-check the label on your device before using it abroad. If it shows “100-240V, 50/60 Hz”, your device is dual voltage and works on both 120V and 220-240V power sources without a converter. This is common for laptops, tablets, smartphones, cameras, and electric toothbrushes.
