United States to Costa Rica: Complete Plug & Adapter Guide (2026) No Adapter Needed

Heading from United States to Costa Rica? 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.

Both United States and Costa Rica use Type A/B plugs, so your devices should plug right in. An adapter isn't strictly necessary for this trip.

The voltage and frequency in Costa Rica (120V, 60Hz) are the same as United States (120V, 60Hz), so your appliances should work without a converter.

Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
