Great news for North American travelers – Aruba uses the same electrical system as the United States and Canada! The standard voltage is 127V at 60Hz frequency, which is essentially identical to the 110-120V used in North America. You'll find Type A and Type B plugs throughout the island (the same two-flat-pin and three-pin grounded plugs used in the US), so American and Canadian devices work perfectly without any voltage converters.

Occasionally you might encounter Type F plugs (the European two-round-pin style) in some older buildings or hotels, but Type A and B are by far the most common. If you're coming from the United States, you won't need any adapters or converters – just plug in your phone chargers, laptops, cameras, hair dryers, and other electronics exactly as you would at home. European visitors will need plug adapters and should check if their devices can handle 127V (most modern electronics are dual-voltage 100-240V and will work fine).

All electronic devices clearly indicate their voltage compatibility on labels or power adapters – look for text like "INPUT: 100-240V, 50/60Hz" which means the device will work anywhere in the world. High-wattage appliances like hair dryers, curling irons, and electric kettles from Europe may require voltage converters if they're not dual-voltage, though purchasing travel-specific dual-voltage versions is often safer than using converters with high-power devices.
