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

Traveling from Saint Lucia 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 Saint Lucia and Costa Rica. Saint Lucia devices use Type G connectors, while Costa Rica sockets are Type A/B. An adapter is a must-have for this destination.

Voltage is another key difference. Saint Lucia 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.

When packing for Costa Rica, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
