Quick answer. Cuba resorts may use different voltages and plug types, sometimes within the same property. Check the label near the outlet and every device charger before plugging anything in.
What to verify
| Item | What to check |
|---|---|
| Outlet voltage | 110–120 V or 220–240 V |
| Plug shape | Flat, round or mixed socket types |
| Device charger | Input range printed on the adapter |
| Adapter | Changes plug shape only, not voltage |
| Voltage converter | Needed only for devices that do not accept the available voltage |
Usually safe dual-voltage devices
Many phone, tablet and laptop chargers accept 100–240 V, but verify the printed input specification. Hair dryers, curling irons and some small appliances may not be dual voltage.
Important. Never use a damaged, loose or overheated outlet. Stop charging immediately if a plug sparks, smells hot or does not fit securely.
Charging during outages
- Charge devices whenever stable power is available.
- Keep a certified power bank in carry-on luggage.
- Use surge protection when practical.
- Do not leave electronics charging unattended overnight.
