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

Getting ready for your journey from Costa Rica to El Salvador? 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 Costa Rica and El Salvador 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 El Salvador (120V, 60Hz) are the same as Costa Rica (120V, 60Hz), so your appliances should work without a converter.

When packing for El Salvador, 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.
