When you are going on a trip to Saint Kitts and Nevis, be sure to pack the appropriate travel plug adapter that fits the local sockets. But what do those electrical outlets look like? Just like the rest of the Caribbean, Saint Kitts and Nevis uses U.S. style plugs and outlets (types A & B), but it also uses the same system (type G) as in the United Kingdom, a legacy of its past as a British colony.
The voltage in Saint Kitts and Nevis is 230 volts and the frequency is 60 Hz.

Like most countries in the Caribbean and North America, Saint Kitts and Nevis uses American-style plugs (types A and B), as the American plug and socket system is pretty much standard across the region. Additionally, British type G receptacles can also be found, a legacy of the country's colonial past.
While American sockets are standard in all households and hotels across the island, only about three quarters of them also provide British power outlets. So, if you want to be on the safe side as a tourist, it is best to pack an adapter that fits type A or B wall outlets.
Keep in mind, however, that travel adapters simply allow a device from one country to be plugged into the wall outlet of another country, but they do not convert electricity. Despite using American-style plugs, Saint Kitts and Nevis's electricity does not run at 120 volts, but at 230 volts, identical to the voltage in the UK. This is why tourists from North and Central America - where the voltage is 120 volts - have to be sure that their appliances can deal with the electricity coming out of the socket. Always check your device's voltage listing: "INPUT: 100-240 V" means that your device is multi-voltage and that it will work with any voltage between 100 V and 240 V. Luckily, many travel gadgets (such as laptops or phone chargers) are multi or dual voltage, so most tourists will not have a problem. If your device is single voltage (e.g. "INPUT: 120V"), you will need a transformer to step down the voltage.
