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

Heading from Costa Rica to Mexico? 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 Costa Rica and Mexico 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 Mexico (127V, 60Hz) are close to Costa Rica (120V, 60Hz), so your appliances should work without a converter.

Most modern phone chargers, laptop adapters, and camera chargers are designed to handle 100-240V input, so they'll work anywhere with just a plug adapter. Heat-producing appliances like hair dryers and flat irons are often single-voltage, so check before you plug them in abroad.
