01The power rule that catches cruisers out
The phone accessories for a cruise that matter most are the ones security will let you keep. Most major cruise lines ban surge protectors, and some ban power strips of any kind, so the charging setup that works in a hotel can end up confiscated at the terminal.
Ships run on their own isolated electrical systems, and lines treat anything that multiplies outlets as a fire risk. Royal Caribbean's prohibited items page, for example, lists extension cords, power strips and multi-plug outlets, while allowing device and USB chargers that carry a recognized US or European safety certification. Other lines draw the line in different places, so read your own line's prohibited items list before you pack.
| Item | Typical cruise policy | Pack it? |
|---|---|---|
| Surge protector or surge power strip | Banned on most major lines | No |
| Non-surge power strip | Varies by line; some ban all strips | Only if your line allows it |
| Extension cord | Commonly banned | No |
| Single-plug charger with several USB ports | Generally allowed | Yes, our pick |
| Power bank | Generally allowed; check for limits | Yes, for excursions |
Lines that take a banned item usually hold it until the end of the cruise. That leaves you a week short on outlets, so buy the right charger before you sail rather than gambling at the terminal.
02Charging in a cabin with one or two outlets
Most cabins have a couple of outlets, usually at the desk or vanity, and they're often nowhere near the bed. Many ships that sail from US ports have US-style outlets, sometimes alongside European ones, but check your ship's details if you're unsure. A family of four with phones, watches and earbuds can easily need six or more charging spots.
The fix is one charger with several USB ports that plugs into a single outlet. It counts as a charger, not a power strip, and it handles every phone in the cabin overnight. If you need to fast-charge two phones at once before an early excursion, a GaN brick with multiple USB-C ports does it in a smaller body. Our guide to multi-port chargers explains how the wattage splits when several devices share one brick.
- Bring a long cable. A 1.5 to 2 m cable lets you charge at the desk and still scroll in bed.
- Count your devices before you pack. One port per device you'll charge overnight, plus one spare.
- Look for a safety mark. UL, ETL or CE marks on the charger itself make it easier to pass inspection on lines that ask for certified chargers.

03Keeping the phone dry on deck and ashore
Pool decks, snorkel stops and tender boats are where cruise phones die. Even an IP68-rated phone isn't built for salt water or chlorine, and an IP rating won't help if the phone sinks off a dock. Pick protection for the kind of day you're planning.

- Floats if dropped in the water
- Keeps sand out of the charging port
- Bulkier in a pocket
Underwater pouch
- Sealed for taking the phone below the surface
- Pair with a lanyard so it can't sink
- Test it with a tissue inside before trusting it
Crossbody lanyard
- Phone stays on you in crowds
- Both hands free for rails and gangways
- No water protection on its own
Before you trust any pouch, close it with a dry paper towel inside and hold it underwater for a few minutes. Our blog post on waterproof pouch ratings explains what the numbers on the box mean. If the phone does get wet, keep it off the charger and follow our liquid detected fix before you plug it in.

04Magnets and the steel cabin wall
Cabin walls on many ships are metal, which is why magnetic hooks are a cruise packing favorite. The same trick works for your phone. A magnetic phone holder stuck to the wall by the bed turns into a nightstand, an alarm clock and a movie screen, without taking up any of the tiny shelf space.
It works best with a MagSafe-compatible case or a magnetic ring on the back of the phone. Keep magnets away from your cruise card if it has a magnetic stripe, the same way you would with hotel key cards. Our guide to magnets and cards covers what's actually at risk.
Stick the holder to your fridge with the phone in its case. If it slides there, it'll slide on a cabin wall when the ship rolls.
05Avoid a surprise data bill at sea
Out at sea, your phone can connect to the ship's own cellular network, and roaming on it is often billed at steep rates that most US plans don't include. Unless your carrier offers a cruise package you've signed up for, the safest setup is airplane mode with Wi-Fi turned back on, using the ship's internet package.
-
Turn off data roaming before you board
On iPhone: Settings > Cellular > Cellular Data Options > Data Roaming. On a Galaxy: Settings > Connections > Mobile networks > Data roaming. Other Android phones keep it under the mobile network settings.
-
Switch on airplane mode once you sail
Then turn Wi-Fi back on. Your phone stays off the ship's cellular network but can still use onboard Wi-Fi and the cruise line's app.
-
Download maps and entertainment at home
Offline maps for each port and downloaded shows save you from slow, metered ship internet.
-
Check in port, not at sea
Near land you may pick up a local network, where your carrier's normal international rates apply. Check those rates before you leave.

Questions people ask
Can I bring a power strip on a cruise?
It depends on the line. Surge-protected power strips are banned on most major lines, and some, including Royal Caribbean, ban power strips and multi-plug outlets entirely. A single-plug charger with several USB ports is the safer choice. Check your line's prohibited items list.
Are power banks allowed on cruise ships?
Power banks are generally allowed in your luggage, but lines can set their own limits, so check yours. If you fly to the port, the airline's rules apply too: carry-on only and 100 Wh or less.
What kind of outlets do cruise ship cabins have?
Many ships sailing from US ports have US-style outlets, sometimes alongside European-style ones. Ships based in Europe or elsewhere may differ. Your cruise line's FAQ or your ship's deck plan details usually say which outlets your cabin has.
Should I put my phone in airplane mode on a cruise?
Usually, yes. At sea your phone can roam onto the ship's cellular network, which is often expensive. Airplane mode with Wi-Fi turned on keeps you on the ship's internet instead. Turn off data roaming too, for extra safety.
Do magnetic hooks work in cruise cabins?
On many ships, yes, because cabin walls and ceilings are metal. A magnetic phone holder works the same way if your phone has a magnetic case or ring. Test the hold on a fridge at home first.
