Sao Tome and Principe to Cuba: Complete Plug & Adapter Guide (2026) Adapter Needed
Whether it's a business trip or a vacation, traveling from Sao Tome and Principe to Cuba requires a quick check on power compatibility. The last thing you want is to arrive and discover your charger doesn't fit the outlets.
Good news: Sao Tome and Principe and Cuba share compatible plug types (Type C). Your existing plugs should fit directly into Cuba's outlets without any adapter needed.
The electrical standards differ significantly: Sao Tome and Principe operates at 230V/50Hz and Cuba at 110V/60Hz. 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.
When packing for Cuba, bring at least one adapter per room if you're traveling with others. Airport shops often sell them at a markup, so ordering one online beforehand saves money. A small power strip from home can also multiply a single adapter into several outlets.
