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

Getting ready for your journey from Mexico to Costa Rica? Electrical compatibility is easy to overlook, but bringing the wrong plug or forgetting an adapter can leave you scrambling at your hotel. Here's what you need to know.

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

The voltage and frequency in Costa Rica (120V, 60Hz) are close to Mexico (127V, 60Hz), so your appliances should work without a converter.

Don't forget that Costa Rica hotel rooms sometimes have a universal shaver socket in the bathroom, but these low-wattage outlets aren't suitable for high-draw devices. For reliable charging, use the standard wall outlets with a proper adapter.
