In St. Lucia, the standard power sockets are Type G, which is the same three-pin rectangular plug used in the United Kingdom. The standard voltage is 230V or 240V and the frequency is 50Hz. If you are traveling from the US or Canada, you will need a plug adapter to fit the sockets, and you must also check if your devices are "dual voltage" (rated for 110-240V). Most modern electronics like laptops and phone chargers are dual voltage and only need the physical adapter. However, simple heating appliances like hair dryers or irons from North America may require a heavy-duty voltage converter to avoid burning out the motor. Many luxury resorts in St. Lucia have installed "universal" outlets or 110V US-style sockets near desks for guest convenience, but it is always wise to bring a Type G adapter just in case.
