Travel Adapter for Costa Rica: Do You Need One? (Philippines → Costa Rica)Adapter Needed

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

Do you need a travel adapter for Costa Rica?

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

What plugs and sockets does Costa Rica use?

Costa Rica 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 the Philippines also uses Type A/B, your plugs already match.

Voltage and frequency in Costa Rica

Costa Rica supplies 120V at 60Hz, which differs notably from the 220V used in the Philippines. This matters most for single-voltage, high-wattage appliances such as hair dryers, straighteners, curling irons, and electric kettles. Plugging a 220V-only device into a 120V outlet can overheat or destroy it. Check each device's label: if it reads "INPUT: 100-240V" it handles both and you only need a plug adapter; if it lists a single voltage, bring a voltage converter or leave it home.

Will your devices work in Costa Rica?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Costa Rica with just your existing plug, and no converter is required. The devices to watch are heat-based appliances: hair dryers, flat irons, and travel kettles are often single-voltage and can fail on Costa Rica's 120V supply. Many travelers simply buy a dual-voltage travel version or rely on the hotel's hair dryer.

What travel adapter should you buy for Costa Rica?

Because the Philippines and Costa Rica 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 Costa Rica

Many Costa Rica 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.
