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

Planning a trip from Vietnam to Costa Rica? One of the first things to sort out before you travel is whether your electronics will work at your destination. Power outlets, plug shapes, and voltage standards vary around the world, and Costa Rica is no exception.

Since Vietnam and Costa Rica both support Type A plugs, you can use your chargers and appliances without a travel adapter. One less thing to worry about.

Be aware that Vietnam runs on 220V at 50Hz, while Costa Rica uses 120V at 60Hz. This voltage difference matters for appliances like hair dryers, curling irons, and electric shavers that aren't dual-voltage. Check the label on your devices. If it says "100-240V," you're fine. Otherwise, you'll need a voltage converter.

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.
