Cuba Power Outlets: Plug Types, 110/220V & Adapters

Verified August 28, 2026: Cuba uses plug and socket types A, B, C and L, with both 110V and 220V at 60 Hz in use. Voltage and socket type can vary by property and even by outlet.

Quick answer: Bring a universal plug adapter. An adapter changes plug shape, not voltage. If your charger says INPUT 100–240V, 50/60Hz, it normally only needs the correct plug adapter. A single-voltage appliance may require a voltage converter.

What plug types are used in Cuba? Types A, B, C and L may be encountered. What voltage is used in Cuba? Both 110V and 220V at 60 Hz are in use, including at hotels and resorts. Never assume every outlet in the same property has the same voltage.

For a resort-specific checklist, see the guide to power outlets at Cuba resorts before charging several devices.

Voltage at Cuba resorts

Many older properties use 110 volts, while newer or renovated hotels may also provide 220-volt outlets. Some rooms label the voltage beside the socket, but not all do. Never assume every outlet in the room is the same.

Common plug types

Travellers may find North American flat-pin outlets, European round-pin outlets or multi-standard sockets. A compact universal travel adapter is usually the simplest solution. A second adapter can help when several devices must charge at once.

Check whether a device is dual voltage

Look at the charger label for an input range such as 100–240V, 50/60Hz. Most modern phone, tablet and laptop chargers are dual voltage and need only a plug adapter. Hair dryers, straighteners, kettles and similar appliances may be single voltage and can be damaged if connected incorrectly.

Adapter versus converter

A plug adapter changes the shape of the plug. It does not change voltage. A voltage converter changes the electricity supplied to a device. High-power appliances can exceed the capacity of small converters, so using the resort appliance or leaving the device at home is often safer.

Preparing for power interruptions

Power interruptions can affect lighting, elevators, air conditioning, water pumps, WiFi and room outlets. Some resorts have generators, but backup coverage may be limited to essential systems.

Charge devices whenever electricity is available. If you carry backup power, review the Air Canada, WestJet and Air Transat power bank rules before packing it in cabin baggage.

Safe charging practices

Use reputable chargers and cables.
Avoid loose, damaged, discoloured or overheating outlets.
Do not overload one socket with several high-power devices.
Disconnect sensitive electronics during repeated flickering or unstable supply.
Keep chargers away from sinks, wet counters and balconies.

Medical and essential devices

Travellers who depend on a CPAP machine, refrigerated medication or another powered medical device should contact the resort and airline before departure. Confirm room voltage, outlet access and backup arrangements.

Do not rely only on a general promise that the resort has a generator. Ask whether the specific room outlet, refrigerator or medical device remains powered during an interruption.
