Cuba to Sao Tome and Principe: Complete Plug & Adapter Guide (2026) Adapter Needed

If you're heading to Sao Tome and Principe from Cuba, it's worth checking the power situation before you pack. Different countries use different outlet types and electrical standards, so your devices may not plug in directly when you arrive.

Good news: Cuba and Sao Tome and Principe share compatible plug types (Type C). Your existing plugs should fit directly into Sao Tome and Principe's outlets without any adapter needed.

The electrical standards differ significantly: Cuba operates at 110V/60Hz and Sao Tome and Principe at 230V/50Hz. For single-voltage appliances (hair straighteners, kettles, etc.), this mismatch could damage your device or even be a safety hazard. Always verify your device's voltage rating before plugging in.

A universal travel adapter with multiple plug configurations is a smart investment if you travel frequently. For Sao Tome and Principe specifically, look for one that supports Type C/F outlets. USB charging ports built into the adapter are a nice bonus.
