Phone, laptop, USB and camera chargers are dual voltage, so they only need the right plug. Single-voltage hair dryers, straighteners and kettles need a converter unless rated for 100–127 V; electric shavers and CPAP machines vary by model. Read the INPUT line on the label. Adapter or converter?
More about sockets in American Samoa
Unlike the United States (Types A and B, 120 V), American Samoa uses Types A, B and I at 120 V, so do not assume an adapter for the United States will fit. No other country or territory in Oceania has exactly this mix of sockets (of 18 in the region). The national plug standard is NEMA 1-15, NEMA 5-15, AS/NZS 3112.
Type I is used due to close proximity with independent western neighbour Samoa.
