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

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

Do you need a travel adapter for Eritrea?

Yes, you'll need a travel adapter. Costa Rica outlets use Type A/B plugs, while Eritrea uses Type C/L. Because the two don't overlap, your Costa Rica plugs physically won't fit Eritrea's sockets without an adapter. Pick one up before you leave, since airport and hotel prices are usually marked up.

What plugs and sockets does Eritrea use?

Eritrea uses these power plug types: Type C (Europlug): two round pins, ungrounded, and the most widely used plug across Europe; Type L: three round pins in a row, the Italian standard. Outlets run at 230V and 50Hz. Coming from Costa Rica (Type A/B), you'll want a Type C/L adapter to match these sockets.

Voltage and frequency in Eritrea

Eritrea supplies 230V at 50Hz, which differs notably from the 120V used in Costa Rica. This matters most for single-voltage, high-wattage appliances such as hair dryers, straighteners, curling irons, and electric kettles. Plugging a 120V-only device into a 230V 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 Eritrea?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Eritrea with just a Type C/L plug adapter, 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 Eritrea's 230V 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 Eritrea?

For Eritrea, look for an adapter that converts your Type A/B plug to Type C/L. A universal travel adapter is the most flexible choice, since it covers Eritrea plus most other destinations and usually adds built-in USB and USB-C ports so you can charge several devices from one socket. If you only ever visit Eritrea, a dedicated Type C/L adapter is smaller and cheaper.

Tips for charging your devices in Eritrea

Many Eritrea 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.
