Saint Vincent and the Grenadines Power Plugs, Wall Sockets & Electrical Outlets
In Saint Vincent and the Grenadines, power plugs and sockets (electrical outlets) of Type A (NEMA 1-15, two flat parallel pins, ungrounded), Type B (NEMA 5-15, two flat parallel pins plus round grounding pin, grounded) and Type G (BS 1363, three rectangular pins in triangular pattern, grounded) are used. Wall sockets run at 110/230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Saint Vincent and the Grenadines.

What Plug Type Does Saint Vincent and the Grenadines Use?
Saint Vincent and the Grenadines power plug standards reflect a mixed electrical heritage, drawing on both North American and British influences. The country uses Type A, Type B, and Type G plugs, giving it a more varied combination of AC power plugs and sockets than many of its Caribbean neighbors. Electricity is supplied at 110:230V, 50Hz, so travelers may encounter different voltages and outlet styles depending on the building.
Type A plugs are the flat, two-pin connectors familiar to anyone who has traveled in North America, while Type B adds a rounded grounding pin for extra safety with larger appliances. Type G, the British-style 3-pin plug, is also found in parts of the country and is easily recognized by its rectangular pins arranged in a triangular pattern with a longer earth pin at the top.
- Type A (NEMA 1-15): two flat parallel pins, ungrounded, 15A, 100-127V
- Type B (NEMA 5-15): two flat pins plus a round grounding pin, grounded, 15A, 100-127V
- Type G (BS 1363): three rectangular pins in a triangular pattern, grounded, 13A, 220-240V
Is a Voltage Converter Necessary?
Because Saint Vincent and the Grenadines operates on a 110:230V, 50Hz supply, whether you need a voltage converter depends on where you are and what you're plugging in. Devices designed for 100-127V systems, such as those built for Type A or Type B outlets, will typically run fine on the lower end of this range, while appliances only rated for 220-240V systems, matching Type G sockets, may need a converter if used elsewhere. Most modern dual-voltage electronics, like phone and laptop chargers, handle this range automatically without any extra equipment.
Plug Sockets, Voltage & Adapters in Saint Vincent and the Grenadines
Travelers should pack an adapter that matches whichever plug type is used at their accommodation, since the mix of Type A, Type B, and Type G outlets means the wall socket in a hotel room may differ from the one in a rental villa. Because Type B outlets are backward compatible with Type A plugs, a Type B adapter offers the most flexibility for devices built for North American plug shapes. Where Type G sockets are installed, only a proper 3-pin plug will fit, so a British-style adapter is essential in those cases.
Grounding and the Earth Pin
Grounding is a key safety feature built into two of the three plug types used in the country. Type B plugs include a round grounding pin that ensures the ground connection is made before power reaches the device, while Type G plugs use a longer rectangular earth pin that also triggers the socket's protective shutters. Type A plugs remain ungrounded and are generally reserved for smaller electronics that don't require earth protection.
Frequently Asked Questions
Yes, since Saint Vincent and the Grenadines uses Type A, Type B, and Type G plugs, you'll likely need an adapter unless your home country already uses one of these plug types. Checking which plug type is installed at your specific accommodation is the best way to bring the right adapter.
Pack an adapter compatible with Type A, Type B, and Type G plugs, since all three are used across the country. A compact travel adapter covering these three types will let you use any wall socket you encounter.
Most modern phone chargers are dual-voltage and can handle the 110:230V range found in Saint Vincent and the Grenadines without a converter. You'll just need the correct adapter for whichever plug type — A, B, or G — matches your outlet.
Some are and some aren't. Type B and Type G outlets include grounding pins for added safety, while Type A outlets are ungrounded and better suited to smaller devices that don't need earth protection.
