From China to American Samoa
When travelling from China to American Samoa: Some of your China plug types fit in American Samoa (A). Bring a compact adapter for the others. Voltage is different (230V → 120V). Check your charger label; if it doesn’t list 120V you’ll also need a voltage converter. Frequency differs (50Hz → 60Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.
