What to Pack for a Cruise
Not a clothing list. This is the gear half - the things a cruise cabin does not have, the things security will take off you at the terminal, and the one item where the three biggest lines publish three different answers.
We have not tested this gear. Every figure here is compiled from published manufacturer specifications and published airline policies, and the arithmetic is public so you can check it. This page contains affiliate links — see the affiliate disclosure.
Three rules settle most of it. Leave the iron and the garment steamer at home — all three lines we checked publish both as prohibited. Check your line’s power strip rule before packing one, because Carnival allows non-surge strips and Royal Caribbean bans strips outright. Take a hanging toiletry bag, because cabin bathrooms have no counter.
Compiled 6 October 2026 from the published prohibited-items policies of Carnival, Royal Caribbean and Norwegian Cruise Line. Policies change and vary by ship — check your own line before you pack.

What the lines publish as prohibited, side by side
Start here rather than with a list of things to bring, because the expensive mistake is packing something that gets taken at the terminal. The three lines do not agree, and on one item they publish opposite rules.
| Item | Carnival | Royal Caribbean | Norwegian |
|---|---|---|---|
| Clothing iron | Prohibited | Prohibited | Prohibited (heating element) |
| Garment steamer | Prohibited | Prohibited | Prohibited (heating element) |
| Power strip / extension cord | Allowed without surge protection | Prohibited outright | Not named on its published list |
| Surge protector | Prohibited by implication — only non-surge cords are allowed | Prohibited | Not named on its published list |
| USB-only charger | Allowed (multi-outlet adapters allowed) | Allowed with a recognized US or European conformity mark | Not named on its published list |
| Hair dryer, curling iron, flat iron | Allowed as personal grooming devices | Allowed; a hair dryer is provided in the stateroom | Allowed when used with proper caution |
| Kettle, hot plate, coffee machine with a hot plate | Prohibited (hot plates, water heaters) | Not named in the entry we read | Prohibited (heating element) |
| Candles and incense | Prohibited | Not named in the entry we read | Prohibited |

The four things a cruise cabin does not give you
A cruise cabin is a small, well-equipped hotel room with four specific gaps, and they are the same gaps on every ship.
- Outlets. Older ships publish two in the whole cabin, both at the desk. Two phones, a watch, a camera and a tablet do not share two outlets. This is the single most common reason people pack a power strip — and the reason the rule above matters.
- Counter space in the bathroom. Cruise bathrooms are the smallest in commercial accommodation. A toiletry bag that stands on a counter has nowhere to stand; a hanging one uses the back of the door. That is the entire argument, and it is why the hanging bag we rank highest is the right shape here even if a flat one works at home.
- Anywhere to put wet swimwear. You will have wet swimwear every day, and the cabin has a shower rail and a hook. A packable laundry sack keeps wet and dry separated in the bag you are also living out of.
- A bag for port days. The suitcase stays in the cabin and you go ashore with a phone, a card, water and a cruise card you cannot lose. That is a sling or a small crossbody, not a daypack — see the sling page.
The kit, costed in published weight
Four items, every figure the maker’s own.
| Item | Published weight | The gap it fills | Line rule to check |
|---|---|---|---|
| NTONPOWER 20W Travel Power Strip | 8 oz | 4 AC outlets and 3 USB in a two-outlet cabin | Allowed on Carnival, prohibited on Royal Caribbean |
| BAGSMART Blast hanging toiletry bag | 10.56 oz | No counter in the bathroom | None |
| Eagle Creek Ranger XE Cross-Body 7L | 7.04 oz | Hands-free bag for port days | None |
| Eagle Creek Packable Laundry Sack (30 L) | 3.7 oz | Wet swimwear, every single day | None |
| Total | 1.83 lb |
1.83 lb for the whole gear list is cheap against a cruise allowance, which is the one genuinely relaxing thing about packing for a ship: there is no carry-on sizer and no 25 lb cap. Our cruise luggage page covers what the lines do publish about bag size, and it is the opposite shape to an airline’s rule.
If you are flying to the port, the airline rules still bind
This trips people up: the cruise allowance is generous and the flight to the port is not. Pack for the tighter of the two, which is always the flight.
- The power strip is fine in either bag on a plane — it has no lithium cell. A power bank is the opposite and must be in the cabin; the battery rules cover it.
- Liquids follow the 3-1-1 rule on the flight and nothing at all once you are aboard, so a full-size bottle has to be in the checked bag. See packing liquids.
- If the flight is the day before the sailing, your medication, documents and one change of clothes belong in the bag that stays with you — the cannot-lose bag.
The embarkation-day bag, which is the only real planning problem
Checked bags go to the terminal porters and arrive at your cabin some hours later. Between boarding and that moment you have only what you carried on, and the ship is open: pools, lunch, muster drill.
So the day bag needs swimwear, medication, documents, a charger and the cruise card. Everything else can wait. This is the single most useful piece of cruise packing advice and it is about sequencing rather than gear — the same logic as deciding what to check on a flight.
The cabin safe, and what it is not for
Every cabin we are aware of has a safe, which puts a cruise in a different category from a hostel. The thing worth knowing is the same thing that is true in a hotel: an in-room safe is a deterrent against opportunism, not a strongbox, and it is opened by staff routinely as part of normal operations. Our hotel safe comparison runs the argument, and it applies at sea unchanged.
What we are deliberately not telling you
This page has no clothing list and no formal-night advice. Dress codes differ by line, by ship and by itinerary, and they are published by the line rather than derivable from anything we can check — so a clothing list here would be invention. Read your line’s own page for that, and use this page for the gear and the prohibitions.
Every pick, with the working
Each entry below shows the published inputs, the four axis scores they produce, and what you give up. The order is the computed order, not a commercial one.
1 · A hotel or cabin where the problem is outlet count, not wattage
NTONPOWER 20W Travel Power Strip (4 outlets, 3 USB)
Four outlets and three USB ports at 0.5 lb, and the only strip here whose absence of surge protection is the selling point rather than a footnote. Read the cruise section before you believe the label.

Warranty 18 month warranty published in the listing
Fits 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY. See the limits.
What it does well
- 4 AC outlets plus 3 USB in 3.93 x 2.28 x 1.25 in and a published 0.5 lb
- No surge protection, which is exactly what Carnival's published policy allows aboard
- 0.39 in flat plug and a wrap-around cord, so it packs flat against a laptop
What you give up
- Rated 125 V — this is a US-voltage strip and does not belong in a 230 V socket
- 20 W on one USB-C port will not charge a laptop; this is a phone-and-watch device
- The cruise-approved claim is true on Carnival and false on Royal Caribbean, which bans power strips outright
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.
- Airline-fit breadth 10.0/10 — Fits the published carry-on limit at 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY
- Carry efficiency not scored — No published capacity, so weight per liter cannot be computed.
- Warranty & support 0.5/10 — 1.5 yr (0.5 of 6); no published repair route (+0); airline damage not covered (+0)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.

2 · Carry-on-only travel inside the TSA 3-1-1 limit
BAGSMART Blast 4.5L Hanging Toiletry Bag
4.5 L in a 10.6 oz bag that hangs — the smallest published toiletry volume here, which is the right size when the liquids rule caps you at a quart anyway.
- Published size
- 10.24 × 5.9 × 4.72 in
- Weight
- 0.66 lb
- Capacity
- 4.5 L
- Weight per liter
- 0.15 lb/L

Warranty No warranty term published
Fits 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY. See the limits.
What it does well
- 4.5 L published capacity is honest about how little liquid you can legally carry
- 10.6 oz published weight
- Hanging hook, which is the only thing that works in a hotel bathroom with no counter
What you give up
- No warranty term published
- 4.5 L is too small if you travel with a full skincare routine
- No separate quart bag included for the security tray
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.
- Airline-fit breadth 10.0/10 — Fits the published carry-on limit at 11 of 11 US carriers: AA, DL, UA, WN, AS, B6, F9, G4, HA, MX, SY
- Carry efficiency 6.1/10 — 0.66 lb ÷ 4.5 L = 0.147 lb/L
- Warranty & support 0.0/10 — no published term (0 of 6); no published repair route (+0); airline damage not covered (+0)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.

3 · The bag you keep on you all day, carried on top of a backpack
Eagle Creek Ranger XE Cross-Body 7L
7 liters at a published 7.04 oz is 0.063 lb per liter — the best carry efficiency of any bag in this ledger — and it carries a warranty with no stated end date. For a sling, that combination is not close.

Warranty No Matter What limited lifetime warranty
Fits 8 of 11 US carriers: AA, UA, WN, B6, F9, G4, MX, SY. See the limits.
What it does well
- 0.063 lb per liter published — nothing else in this ledger is lighter for its volume
- The No Matter What warranty names no end date, on a 7 L bag
- 15.75 x 7 x 3.5 in clears every published US personal-item box we track
What you give up
- No anti-theft features published — no locking zippers, no slash panels, no RFID
- 7 L will not take a laptop, only a tablet-sized item at most
- No manufacturer-published price, so cost per liter cannot be fixed
The arithmetic behind the score
- Value not scored — No manufacturer-published price, so this axis is not scored.
- Airline-fit breadth 10.0/10 — Fits the published personal-item limit at 8 of 8 US carriers: AA, UA, WN, B6, F9, G4, MX, SY
- Carry efficiency 9.5/10 — 0.44 lb ÷ 7 L = 0.063 lb/L

4 · Trips long enough that clean and dirty need separating
Eagle Creek Packable Laundry Sack (30 L)
30 liters of dirty-clothes capacity for a published 3.7 oz that folds to 7 x 6 x 1 in — the best ratio of deployed volume to packed volume anywhere in this ledger.
- Published size
- 25 × 18 × 1 in
- Weight
- 0.23 lb
- Capacity
- 30 L
- Weight per liter
- 0.01 lb/L
- Cost per covered year
- $1.50/yr
- Published list price
- $30
Warranty No Matter What limited warranty
Fits No US carrier in our table publishes a limit these dimensions satisfy. See the limits.
What it does well
- 30 L deployed from a 7 x 6 x 1 in packed size — it costs almost no space until you need it
- PU-coated nylon, so damp clothes do not soak through to the rest of the bag
- No Matter What warranty with a published repair route
What you give up
- A coating is a moisture barrier, not an odor barrier
- $30 for what is functionally a lined stuff sack
- 3.7 oz is more than double a plain nylon sack of the same volume
The arithmetic behind the score
- Value 10.0/10 — $30 ÷ 20 yr = $1.50/yr; $30 ÷ 30 L = $1/L
- Airline-fit breadth 0.0/10 — Fits the published carry-on limit at 0 of 11 US carriers
- Carry efficiency 10.0/10 — 0.231 lb ÷ 30 L = 0.008 lb/L
- Warranty & support 8.0/10 — no stated end date (6 of 6); repair published (+2); airline damage not covered (+0)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.
Specs: Eagle Creek published specifications and price, compiled 3 September 2026. Eagle Creek publishes 25 x 18 in expanded and 7 x 6 x 1 in packed. The expanded figures are used here.
5 · Anyone steaming clothes outside North America
Conair Power Steam Worldwide Travel Garment Steamer (GSC24)
Skip this one. Do not pack it. All three lines we checked publish garment steamers and clothing irons as prohibited items: Carnival names both under prohibited electrical heating devices, Royal Caribbean names 'clothing irons and garment steamers', and Norwegian prohibits anything containing a heating element and names clothing irons specifically. This is one of the most commonly confiscated items at a cruise terminal. Every line we checked publishes that hair dryers, curling irons and flat irons ARE allowed - the ban is on items that heat a garment, not on personal grooming devices.
Published dual voltage at $49.99 - which, in a category where the premium option is single-voltage, makes this the only steamer here that works in Europe.

What it does well
- Published dual voltage switch for worldwide use
- $49.99 published, half the price of the Steamery
- 35-second heat-up published
What you give up
- 2.35 lb published, heavier than the single-voltage alternative
- The dual voltage switch must be set by hand
- No warranty term read from a manufacturer page
The arithmetic behind the score
- Value not scored — No published warranty term or capacity to divide the price by.
- Airline-fit breadth not scored — No published dimensions to check against carrier limits.
- Carry efficiency not scored — No published capacity, so weight per liter cannot be computed.
- Warranty & support 0.0/10 — no published term (0 of 6); no published repair route (+0); airline damage not covered (+0)
Weights and breakpoints are published on how we rank. Where an input is not published, that axis is dropped and the remaining weights are re-normalized.
