Check the exact ship and cabin
A cabin may provide several socket systems or USB outlets. Voltage and outlet count can also vary by ship and refurbishment. Ask the operator or consult the ship information before choosing an adapter.
Onboard rules can be stricter than hotel rules
Cruise lines restrict electrical items to reduce fire and overload risks. Royal Caribbean, for example, lists extension cords, power strips and multi-plug outlets as prohibited by default, while chargers with recognised conformity marking may be allowed.
Policies differ, so this example must not be treated as a universal cruise rule.
Practical preparation
- ✓Ask which socket types and voltage are available on the exact ship.
- ✓Pack only a suitable, undamaged travel adapter.
- ✓Do not pack a power strip or extension cord unless expressly permitted.
- ✓Check hair dryers, irons, steamers and other heating appliances separately.
