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

Traveling from Tonga to Costa Rica means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in Costa Rica so you can keep all your devices charged and ready.

There's no plug compatibility between Tonga and Costa Rica. Tonga devices use Type I connectors, while Costa Rica sockets are Type A/B. An adapter is a must-have for this destination.

Voltage is another key difference. Tonga uses 240V while Costa Rica uses 120V. 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.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Costa Rica specifically, look for one that supports Type A/B outlets. USB charging ports built into the adapter are a nice bonus.
