Q. 01
Can I bring a power strip on a cruise?
On most lines yes — Carnival, Norwegian, Princess, Celebrity, Disney, Holland America, MSC, and the European and British lines (Cunard, P&O, Costa, Marella) all allow non-surge power strips (no surge protection, no indicator light). Royal Caribbean is the exception: since 2024 it bans all power strips, multi-plug adapters and extension cords fleet-wide. The 2024 policy was expanded later that year to also prohibit multi-plug outlets. Surge protectors are banned across every cruise line, period.
Q. 02
Why are surge protectors banned on cruise ships?
A surge protector's internal MOV (metal-oxide varistor) circuitry is built for a building's grounded electrical system. On a ship's isolated electrical ground, it can fail in a way the vessel's ground-fault detection reads as a fault, which the line treats as a fire risk. Cruise security checks for surge protection at embarkation — anything with an indicator LED, the word 'surge', or a printed joule rating gets confiscated and returned at disembarkation.
Q. 03
What's the difference between a power strip and a surge protector?
A surge protector has internal circuitry — usually with a glowing 'protected' LED — that clamps voltage spikes. That's the part cruise lines object to. A plain power strip is just a passive bar of outlets with no surge circuitry and no light. Functionally a power strip multiplies outlets without protecting against voltage spikes. Cruise lines accept the passive strips (except Royal Caribbean) and reject anything with surge circuitry.
Q. 04
What power strip is allowed on Royal Caribbean?
None — Royal Caribbean banned every power strip, multi-plug AC adapter, and extension cord fleet-wide in 2024. Having no surge protection makes no difference. The only outlet-multiplier RC allows is a charger that plugs into a single AC outlet and provides USB ports — a USB charging cube — as long as it carries recognized US or EU CE conformance markings.

Q. 05
Can I bring an extension cord on a cruise?
On most lines, yes — a basic non-surge extension cord is allowed, though rarely useful in a small cabin. On Royal Caribbean, extension cords are banned along with power strips. Either way, there's a medical exception on most lines: if you need an extension cord for a CPAP or other medical device, file the Special Needs form 30+ days before sailing and the ship will supply a compliant cord plus distilled water in your cabin (RCL does this for medical use even inside the broader strip ban).
Q. 06
What should I pack to charge my devices on a cruise instead?
A compact USB charging hub — one wall plug, three to six USB ports, ideally with both USB-C and USB-A. It works in any cabin, on any line, and it's the only outlet-multiplier Royal Caribbean allows. If you also need a second AC outlet for a non-USB device (CPAP charger, camera battery, curling iron), add a non-surge power strip — but only on lines that allow them (everything except Royal Caribbean). Pack everything in your carry-on so it stays under your control through embarkation.
