If you’re already abroad and forgot your power adapter, don’t stress. You can usually get by just fine. But having one with you from the beginning adds a little peace of mind—and makes settling in that much easier.
Travelers to the Cook Islands often continue to New Zealand, French Polynesia, or Samoa. Be sure to check which plug you’ll need.
Do You Need a Voltage Converter?
In the Cook Islands, the power supply operates on a different voltage than the U.S. standard of 120V, so a voltage converter is likely required for your devices to work properly.
Always check your device’s power label before traveling. If it says “100-240V, 50/60 Hz”, your device can handle different voltages worldwide without needing a converter. This applies to most laptops, tablets, cameras, phones, and rechargeable personal care devices.
