From Cambodia to Guam
When travelling from Cambodia to Guam: Some of your Cambodia plug types fit in Guam (A, B). Bring a compact adapter for the others. Voltage is different (230V → 110V). Check your charger label; if it doesn’t list 110V 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.
