El Salvador to Sao Tome and Principe: Complete Plug & Adapter Guide (2026) Adapter Needed
Getting ready for your journey from El Salvador to Sao Tome and Principe? 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 El Salvador plugs (Type A, B) won't fit Sao Tome and Principe's outlets (Type C, F). You'll want to grab a universal travel adapter or one specifically designed for Sao Tome and Principe before you depart.
Be aware that El Salvador runs on 120V at 60Hz, while Sao Tome and Principe uses 230V at 50Hz. 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.
Rather than packing bulky converters, consider buying travel-sized dual-voltage versions of appliances you can't live without. For phones and laptops, all you'll need is the right plug adapter since their chargers almost always support worldwide voltage.
