Do I Need a Power Adapter or Converter in the Caribbean?

If you’re planning a Caribbean vacation, you’re probably dreaming about beaches, cocktails, and sunshine—not electrical outlets. But before you pack your phone, camera, or hair tools, it’s important to know: Will your plugs work in the Caribbean? The answer depends on which island you’re visiting.

Caribbean Power Outlets and Voltage: The Basics

• Most Caribbean islands (including Jamaica, Bahamas, Puerto Rico, U.S. Virgin Islands, and the Dominican Republic):

  • Plugs: Type A/B (the same flat-prong plugs used in the U.S.)

  • Voltage: 110–120V (same as the U.S.)

  • 👉 Good news: If you’re coming from the U.S., you typically don’t need an adapter or converter here.

• Some Caribbean islands with European influence (like Aruba, Bonaire, Curaçao, St. Maarten, Martinique, Guadeloupe, and Barbados):

  • Plugs: Often a mix of U.S. Type A/B and European Type C/F (two round prongs)

  • Voltage: Frequently 220–240V

  • 👉 What this means: You may need an adapter for your plug, and if your device isn’t dual voltage, a converter too.

What’s the Difference Between an Adapter and a Converter?

• Adapters: Change the shape of your plug so it fits into a foreign outlet. They do not change the voltage.

  • Example: Charging your iPhone in Curaçao? If your charger is dual voltage (most are), you’ll only need a small adapter.

• Converters: Change the voltage of the electricity (e.g., 220V down to 110V). You’ll only need one if your device is single voltage.

  • Example: A U.S.-only 110V curling iron won’t survive in Aruba without a converter.

How to Know If You Need a Converter in the Caribbean

1. Check your device’s label. If it says 100–240V, it’s dual voltage → adapter only.

2. If it says 120V only, it’s single voltage → adapter + converter required.

3. Most modern electronics (phones, tablets, laptops, cameras) are dual voltage.

4. High-wattage items like hairdryers, curling irons, and straighteners are most likely single voltage.

Quick Caribbean Plug Guide

• No adapter/converter needed:

  • Jamaica, Bahamas, Puerto Rico, U.S. Virgin Islands, Turks & Caicos, Dominican Republic

• Adapter (and maybe converter) needed:

  • Aruba, Bonaire, Curaçao, Barbados, St. Maarten, Martinique, Guadeloupe, and some smaller islands

💡 Pro Tip: If you’re visiting multiple islands or going on a cruise, pack a universal travel adapter to be safe.

Final Word: Stay Powered Up in the Caribbean

• If your island uses U.S.-style outlets (110V), you’re set—no extra gear needed.

• If your island uses European-style outlets (220V), bring an adapter and check whether your devices are dual voltage.

A little preparation ensures you can charge your phone, snap photos, and stay connected without worry.
