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

Traveling from Costa Rica to Dominican Republic means crossing into a different electrical system. Before you leave, take a moment to understand the plug types and voltage used in Dominican Republic so you can keep all your devices charged and ready.

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

On the voltage front, Costa Rica (120V, 60Hz) and Dominican Republic (120V, 60Hz) are identical. You shouldn't need a voltage converter for your electronics.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Dominican Republic specifically, look for one that supports Type A/B outlets. USB charging ports built into the adapter are a nice bonus.
