Travel Adapter for Dominican Republic: Do You Need One? (Costa Rica → Dominican Republic)No Adapter Needed

Traveling from Costa Rica to the Dominican Republic means crossing into a different electrical system. Here's a complete breakdown of the sockets, voltage, and the right adapter to bring for the Dominican Republic, so nothing you packed ends up useless at the hotel.

Do you need a travel adapter for Dominican Republic?

Good news: you generally don't need a plug adapter. Both Costa Rica and the Dominican Republic use Type A/B outlets, so your existing plugs should fit the Dominican Republic's sockets directly. A universal adapter is still worth keeping in your bag as a backup for future trips.

What plugs and sockets does Dominican Republic use?

the Dominican Republic uses these power plug types: Type A: two flat parallel pins (ungrounded), the standard North American and Japanese plug; Type B: two flat pins plus a round grounding pin, common in North America. Outlets run at 120V and 60Hz. Since Costa Rica also uses Type A/B, your plugs already match.

Voltage and frequency in Dominican Republic

the Dominican Republic runs on 120V at 60Hz, the same as Costa Rica (120V, 60Hz). That means voltage isn't a concern here, since your appliances won't be over- or under-powered, so no voltage converter is needed.

Will your devices work in Dominican Republic?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in the Dominican Republic with just your existing plug, and no converter is required. Even heat-based appliances like hair dryers and straighteners should run fine given the matching 120V supply, though it's always worth a quick label check.

What travel adapter should you buy for Dominican Republic?

Because Costa Rica and the Dominican Republic share Type A/B outlets, you don't need a special adapter for this trip. A universal travel adapter is still a smart, inexpensive backup if you plan to travel elsewhere, and the better ones add USB-C fast charging to free up your charger.

Tips for charging your devices in Dominican Republic

Many the Dominican Republic hotel bathrooms have a low-wattage "shaver only" socket that is fine for razors and toothbrushes but not for charging phones or running hair dryers. Use the main wall outlets with your adapter for everything else.
