Eritrea to Costa Rica: Complete Plug & Adapter Guide (2026) Adapter Needed
Getting ready for your journey from Eritrea to Costa Rica? 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.
Your Eritrea plugs (Type C, L) won't fit Costa Rica's outlets (Type A, B). You'll want to grab a universal travel adapter or one specifically designed for Costa Rica before you depart.
Be aware that Eritrea runs on 230V at 50Hz, while Costa Rica uses 120V at 60Hz. This voltage difference matters for appliances like hair dryers, curling irons, and electric shavers that aren't dual-voltage. Check the label on your devices. If it says "100-240V," you're fine. Otherwise, you'll need a voltage converter.
A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Costa Rica specifically, look for one that supports Type A/B outlets. USB charging ports built into the adapter are a nice bonus.
