Costa Rica to Nauru: Complete Plug & Adapter Guide (2026) Adapter Needed

Heading from Costa Rica to Nauru? Plug types and voltage standards differ between countries, so a little preparation goes a long way. Here's a breakdown of what to expect at the wall socket.

Costa Rica uses Type A and B plugs, while Nauru uses Type I. Since there is no overlap, you will need a travel adapter to plug in your devices. Make sure to pick one up before your trip or at the airport.

Voltage is another key difference. Costa Rica uses 120V while Nauru uses 240V. If your device only supports one voltage, using it with the wrong supply could cause overheating or permanent damage. Look for "Input: 100-240V" on your charger. Most modern phone and laptop chargers support this range.

Don't forget that Nauru hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
