Travel Adapter for Sao Tome and Principe: Do You Need One? (Cuba → Sao Tome and Principe)Adapter Needed

If you're heading to Sao Tome and Principe from Cuba, sorting out the power situation is one of the easiest pre-trip wins. Below you'll find the plug types, voltage, and frequency used in Sao Tome and Principe, whether you need an adapter, and which devices are safe to plug in.

Do you need a travel adapter for Sao Tome and Principe?

Good news: you generally don't need a plug adapter. Both Cuba and Sao Tome and Principe use Type C outlets, so your existing plugs should fit Sao Tome and Principe's sockets directly. A universal adapter is still worth keeping in your bag as a backup for future trips.

What plugs and sockets does Sao Tome and Principe use?

Sao Tome and Principe uses these power plug types: Type C (Europlug): two round pins, ungrounded, and the most widely used plug across Europe; Type F (Schuko): two round pins with grounding clips on the sides, standard in Germany and much of Europe. Outlets run at 230V and 50Hz. Since Cuba also uses Type C, your plugs already match.

Voltage and frequency in Sao Tome and Principe

Sao Tome and Principe supplies 230V at 50Hz, which differs notably from the 110V used in Cuba. This matters most for single-voltage, high-wattage appliances such as hair dryers, straighteners, curling irons, and electric kettles. Plugging a 110V-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 Sao Tome and Principe?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Sao Tome and Principe 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 Sao Tome and Principe'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 Sao Tome and Principe?

Because Cuba and Sao Tome and Principe share Type C 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 Sao Tome and Principe

Pack at least one adapter per traveler, and consider a small power strip from home, which turns a single Sao Tome and Principe outlet into several. Ordering online before you fly is almost always cheaper than airport kiosks.
