Do your plugs fit in Thailand?

Good news — at least one of your plug types from the United States fits the sockets in Thailand, so you don't strictly need an adapter (though a universal adapter is handy if you travel often).

Do you need a voltage converter in Thailand?

⚡
Mind the voltage. The standard voltage in Thailand (230V) is much higher than in the United States (120V). Without a converter you risk serious damage to your devices.
🕐
Frequency differs. The frequency in Thailand (50Hz) differs from the United States (60Hz). Be extra careful with motorised devices and items with timers or motors (clocks, shavers, some medical devices).

Many chargers (phones, laptops, cameras) are labelled INPUT: 100–240V, 50/60Hz — those work anywhere and only need a plug adapter, never a converter. Always check the label.
