United States Virgin Islands Power Plugs, Wall Sockets & Electrical Outlets
In United States Virgin Islands, power plugs and sockets (electrical outlets) of Type A (NEMA 1-15, two flat parallel pins, ungrounded) and Type B (NEMA 5-15, two flat parallel pins plus round grounding pin, grounded) are used. Wall sockets run at 110V and 60Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to United States Virgin Islands.

Do You Need a Travel Adaptor for United States Virgin Islands?
If you are travelling from a country that uses Type A or Type B plugs, such as the United States or Canada, you will not need a travel adaptor to use your devices in the United States Virgin Islands. The territory runs on the same electrical standard as mainland North America, operating at 110V and 60Hz, with Type A and Type B sockets found in homes, hotels, and businesses throughout the islands. However, if you are arriving from Europe, the UK, Australia, or most of Asia, where plug shapes and voltages differ, a United States Virgin Islands power plug adaptor will be essential for connecting your devices safely.
Dual-Voltage Devices and United States Virgin Islands
Many modern electronics, including phone chargers, laptop power supplies, and camera battery chargers, are dual-voltage and designed to work on a range of electrical systems worldwide. If your device is rated for 100-127V (as is standard for Type A and Type B equipment), it will function normally on the local 110V, 60Hz supply without needing a voltage converter. Always check the small print on your charger or the plug top itself, as it will state the accepted voltage range; if it only lists 220-240V, you will need a separate voltage converter rather than just a plug adaptor.
Where to Buy a Travel Adapter for United States Virgin Islands
Travel adaptors suited to the United States Virgin Islands are widely available before you travel, including at airport shops, electronics retailers, luggage stores, and online marketplaces. Look for an adaptor labelled for use in the USA or North America, since this will match the Type A and Type B socket-outlet configurations used across the territory. It is generally cheaper and more convenient to buy your travel adaptor at home rather than waiting until you arrive, as local availability on the islands can be limited.
Power Sockets and Plug Types in United States Virgin Islands
The United States Virgin Islands uses the same plug and socket standards as the US mainland: Type A and Type B. Type A is an ungrounded plug with two flat parallel pins, commonly used for small electronics, lamps, and phone chargers that do not require a safety ground connection. Type B is the grounded counterpart, adding a round grounding pin alongside the two flat blades, and is required for larger appliances, computers, and power tools where grounding protection is important.
- Type A (NEMA 1-15): ungrounded, two flat parallel pins, 15A, 100-127V
- Type B (NEMA 5-15): grounded, two flat pins plus round grounding pin, 15A, 100-127V
- Standard voltage: 110V
- Standard frequency: 60Hz
Frequently Asked Questions
You only need a travel adaptor if your home country uses a different plug shape than Type A or Type B. Travellers from the US, Canada, and similar countries can use their existing plugs without any adaptor, since the islands use the same Type A and Type B sockets.
Both grounded and ungrounded sockets are used in the United States Virgin Islands. Type B sockets are grounded, featuring a round grounding pin alongside two flat blades, while Type A sockets are ungrounded and rely only on two flat parallel pins.
If your devices already use Type A or Type B plugs, you don't need to pack anything extra. Travellers with different plug types should bring a compact travel adaptor configured for Type A/Type B outlets, and a voltage converter if their devices aren't rated for 100-127V.
Yes, most phone chargers are dual-voltage and designed to accept 100-127V, matching the local 110V, 60Hz supply. As long as your charger has a Type A or Type B plug, or you use a simple plug adaptor, you can charge your phone without needing a voltage converter.
