The voltage in Barbados is 110-120 volts, which is the same as the USA and Canada. Standard plug types on the island are two flat blades or two flat blades and a round grounding pin. For 220-240 voltage appliances you will need to bring an adapter and transformer. Most hotels on the island can provide their guests with adapters and transformers for appliances such as hair dryers but we suggest that you check with your accommodation before you travel.
