From Brazil to Cuba
When travelling from Brazil to Cuba: None of your Brazil plug types fit in Cuba. You will need a travel adapter. Voltage is different (127V / 220V → 120V). Check your charger label; if it doesn’t list 120V you’ll also need a voltage converter. Frequency is the same at 60Hz.

About electricity in Cuba
Cuba uses 120V/60Hz with Type A and B sockets, broadly North American compatible.
Grid & history
Cuba’s grid is in chronic crisis, aging Soviet-era oil-fired plants, fuel shortages, and limited investment have caused multi-hour scheduled outages nationwide. Tourist hotels usually have generator backup.
Availability
Very unreliable nationwide. Tourist hotels almost always have generators.
Sockets & hotels
Officially Type A/B at 120V, but some older buildings still have 220V sockets (from the Soviet era). Verify before plugging in.
Energy mix
Practical tips
- US plugs fit modern Cuban sockets directly.
- Bring a high-capacity power bank, outages are routine.
- Older buildings may still have 220V Type C sockets in places. Verify voltage first.
