St. Lucia uses Type G (three rectangular pins (UK/Ireland/Singapore/Hong Kong style)).
Yes — St. Lucia's outlets use a different shape than US plugs, so you'll need a plug adapter.
St. Lucia runs on 240V at 50Hz, notably different from the US standard of 120V — check that your device is rated for this voltage before plugging in directly.
Most modern electronics (phone and laptop chargers) are dual-voltage (100-240V) and only need a plug adapter, not a converter. Single-voltage, high-wattage devices like hair dryers or straighteners may need an actual voltage converter — check the label near the plug prongs for the input voltage range.
