Do I need a plug adapter on a cruise ship?

For the cabin itself: if you're a US traveller on a mainstream cruise line, usually not — 110V US-style outlets are standard. However, you will almost certainly need adapters for port stops, especially on European, Mediterranean, or Caribbean itineraries where ports use different socket types. Pack adapters for each country on your itinerary.

How many outlets are in a cruise ship cabin?

Most standard cruise cabins have just 1–3 outlets — typically 1 or 2 near the desk/vanity area. Newer ships increasingly add USB ports (USB-A and sometimes USB-C). This is rarely enough for couples or families travelling with multiple devices, which is why a permitted multi-port USB hub is strongly recommended.

Cruise ship electricity guide — outlets, voltage & what to pack

Q: What voltage do cruise ship cabins use?

Most cruise ships built or refitted for a global passenger market provide both 110V (US-style) and 220V outlets in cabins. Older ships or those flagged for specific markets may have only one voltage. Royal Caribbean, Carnival, Norwegian, MSC, and Celebrity all provide at least 110V in cabins; many newer ships also offer 220V and USB-A/USB-C ports.

Q: Are power strips allowed on cruise ships?

Standard power strips are banned on virtually all cruise ships as a fire hazard. Cruise lines including Royal Caribbean, Carnival, Norwegian, MSC, and Disney ban power strips outright. Some lines allow a power strip with no surge protection and no extension cord — but policies vary. Your safest option is a compact multi-port USB charging hub, which is permitted on all lines.

Q: What adapter do I need for a Mediterranean cruise?

A Mediterranean cruise typically crosses several plug standards: Type C/F (most of Europe and Greece), Type G (UK if you stop there), and Type L (Italy, specifically older Italian sockets). A universal travel adapter covering A, C/E/F, G, and I will handle all of these. Don't rely on the ship's cabin outlets for shore power — bring a port-stop adapter kit.

Q: Can I bring a surge protector on a cruise ship?

No. Surge protectors are banned on almost all cruise lines, including Royal Caribbean, Carnival, Norwegian, and Celebrity. This is a fire-safety rule — surge protectors can cause electrical fires in ship environments. Bring a multi-port USB charging hub instead, which is universally permitted.

Cruise cabins have fewer outlets than a budget hotel room, power strips are banned on almost every ship, and your Mediterranean itinerary may cross three different plug standards. Here's everything you need before you board. Published October 2026 · By Michael Johnson Most mainstream cruise ships provide 110V US-style outlets (and often 220V) in cabins — so US travellers rarely need a cabin adapter. What you do need: a multi-port USB charging hub (power strips are banned), and plug adapters for every country on your port-stop itinerary.

Cabin outlets: voltage, socket types, and how many to expect

Cruise ship cabins are notoriously under-provisioned for outlets. Most standard cabins have 1–3 outlets near the vanity or desk — nowhere near enough for two people with phones, cameras, tablets, and CPAP machines. Newer ships are better, often adding USB-A ports (and occasionally USB-C), but they still lag behind hotels.

The good news: most modern cruise ships serving a North American or international passenger base provide at least 110V US-style outlets, and many newer ships also include a 220V outlet for European passengers. Here's what the major lines offer:

Cruise line	Cabin voltage	Socket types	USB ports
Royal Caribbean	110V + 220V	US Type A/B + European Type C	USB-A at desk (newer ships add USB-C)
Carnival Cruise Line	110V	US Type A/B only on older ships; newer ships add 220V	USB-A on newer ships
Norwegian Cruise Line	110V + 220V	US Type A/B + European Type C	USB-A on most ships
MSC Cruises	220V primary + 110V shaver outlet	European Type C primary; 110V shaver socket in bathroom	USB-A on newer ships
Celebrity Cruises	110V + 220V	US Type A/B + European Type C	USB-A; newer ships have USB-C
Princess Cruises	110V + 220V	US Type A/B + European Type C	USB-A on most ships
Disney Cruise Line	110V + 220V	US Type A/B + European Type C	USB-A on most ships
Holland America	110V + 220V	US Type A/B + European Type C	USB-A on most ships
P&O Cruises (UK)	220–240V primary + 110V shaver socket	UK Type G primary; 110V shaver socket	USB-A on newer ships
Cunard	110V + 220V	US Type A/B + UK Type G	USB-A
Costa Cruises	220V + 110V shaver socket	European Type C primary	USB-A on newer ships
AIDA Cruises	220V	European Type C/F	USB-A on some ships

Cabin specs can vary by ship within the same cruise line — older vessels may differ from newer ones. Always confirm with your cruise line before sailing.

Key takeaway for US travellers: On Royal Caribbean, Carnival, Norwegian, Celebrity, Princess, and Disney, your US plugs will work without an adapter in the cabin. On MSC, P&O, Costa, and AIDA, you'll want either a Type C adapter or a dual-voltage device setup.

Key takeaway for UK travellers: Most ships will have a Type C (European) outlet rather than Type G. Bring a Type G to Type C adapter, or a universal adapter. Cunard is the notable exception with Type G available.

⚠️ Power strips and surge protectors are banned on cruise ships

This catches nearly every first-time cruiser off guard. Power strips, extension cords, and surge protectors are prohibited on virtually all cruise ships — including Royal Caribbean, Carnival, Norwegian, MSC, Celebrity, Princess, and Disney. The reason is fire safety: a ship's electrical system and confined spaces make power strip fires extremely dangerous.

Items that will be confiscated at embarkation or flagged during a cabin inspection: surge-protecting power bars, extension leads, multi-plug adapters with a cord, and any power strip regardless of surge protection status.

What is allowed: A compact multi-port USB charging hub that plugs directly into the wall (no extension cord, no surge protection circuitry) is permitted on all major cruise lines. These typically provide 4–6 USB-A and USB-C ports from a single outlet. This is the single most useful thing you can pack for a cruise.

What to pack for the cabin

Given the outlet scarcity and power-strip ban, here's what actually works:

Multi-port USB charging hub (wall-plug style, no cord) — turns one outlet into 4–6 USB charging ports. Essential for couples or families. Look for one with both USB-A and USB-C ports, rated at least 65W total output.
GaN compact multi-port charger — newer GaN (gallium nitride) chargers pack 65–100W into a palm-sized unit with 2–4 USB-C/USB-A ports. One unit charges a laptop, phone, and tablet simultaneously from a single outlet. See our adapter guide for recommended models.
Short charging cables — the desk outlet is often far from the bed. A 1m cable keeps your setup tidy in a small cabin.
Universal travel adapter — not always needed for the cabin itself, but essential for port stops (see below). A universal adapter covering Type A/B, C/E/F, G, and I covers virtually every destination.

Leave at home: power strips, extension leads, surge protectors, travel kettles (also banned on most ships), and any appliance that draws over 1,000W (hair dryers — use the one provided in the cabin bathroom).

Hair dryers on cruise ships

Almost all cruise lines provide a hair dryer in the cabin — either wall-mounted in the bathroom or in a drawer. These are supplied by the ship and are correctly rated for the ship's voltage. Do not bring your own full-size hair dryer — they draw 1,500–2,000W, they are often restricted by ship policy, and the ship's version works fine for the cabin's voltage.

If you insist on your own hair styling tools, the rules are the same as for any international travel: only use a dual-voltage (100–240V) travel hair dryer or straightener. See: why your hair dryer is dangerous abroad and dual voltage devices guide.

Port stops: the part most people don't prepare for

The cabin is only half the story. If you spend any time ashore — in a hotel, rented apartment, shore excursion facility, or charging point — you're subject to that country's plug type and voltage.

A Mediterranean cruise, for example, can cross all of these plug standards in a single week:

Port / Country	Plug type	Voltage	Notes
Spain, France, Greece	Type C / E / F	230V	Round two-pin (Europlug / Schuko)
Italy	Type L (+ Type C/F)	230V	Older Italian sockets are Type L only — check before plugging in
UK (Southampton, Dover)	Type G	230V	Unique three-rectangular-pin UK socket
Morocco	Type C / E	220V	Same as most of Europe
Turkey	Type C / F	220V	Schuko compatible
Israel	Type H (+ Type C)	230V	Unique triangular Type H; many sockets also accept Type C
Egypt	Type C / G	220V	Mix of both — check each outlet
Caribbean (most islands)	Type A / B	110–120V	US-style — US travellers need no adapter
Barbados, St Lucia, Antigua	Type A / B / G	110–230V	Mix varies by island and property
Norway, Sweden, Denmark	Type C / F	230V	Schuko / Europlug standard
Alaska ports (US)	Type A / B	120V	No adapter needed for US travellers

The practical solution: A single universal travel adapter covering Types A/B, C/E/F, G, and I handles every destination in the table above. Buy one before you sail — they are sold on board at inflated prices, and small ports may not stock them at all.

Adapters by cruise type

Match your adapter kit to your itinerary:

Cruise type	Adapter you need	Notes
Caribbean (from US)	Usually none	Most Caribbean islands use Type A/B (US-style). Check individual island guides for exceptions.
Mediterranean (from US)	Universal adapter (A/B + C/E/F + G)	Cover European round-pin, UK three-pin, and Italian Type L. A universal handles all.
Northern Europe / Baltic (from US)	Type C/E/F adapter	Consistent Schuko/Europlug standard across Norway, Sweden, Denmark, Finland, Germany, Estonia, Latvia, Lithuania. No UK stops — skip Type G unless your itinerary includes the UK.
Alaska (from US)	None	US ports — no adapter needed.
Asia-Pacific (from US)	Universal adapter	Japan (Type A, 100V — check dual voltage), Australia (Type I), Vietnam (Type A/C mix), China (Type A/C/I mix). Check each destination.
Any cruise (from UK)	Type G → Type C adapter for cabin (most ships); Type C/E/F for European ports; Type A/B for Caribbean/US ports	UK travellers on Cunard can skip the cabin adapter. Everyone else needs one for the cabin.

CPAP machines and medical devices on cruises

CPAP machines are allowed on all major cruise lines. Most modern CPAP devices (post-2015) are dual voltage (100–240V), which means they'll work on the ship's cabin supply with only a plug adapter. Check your specific machine's power supply label before you travel.

Important notes for CPAP users on cruises:

Request a cabin with a bedside outlet in advance — standard cabins often only have desk outlets. Many cruise lines offer CPAP-friendly cabin options; call to request one.
Bring distilled water for your humidifier — ship tap water (and water at most ports) is not suitable for CPAP humidifiers. Pack enough for the voyage or ask the ship's medical centre.
Extension cords are banned — but CPAP machines are a medical device and cruise lines will often make an exception for a short extension cord if you contact medical services in advance. Ask before you sail.
For older single-voltage CPAPs: check your machine's label. If it shows 110–120V only, you'll need a step-up converter for 220V ships — contact your CPAP supplier before travelling.

Frequently asked questions

What voltage do cruise ship cabins use?

Most major cruise lines built for an international market provide both 110V (US-style) and 220V outlets in cabins. Ships primarily serving European passengers (MSC, P&O, AIDA, Costa) lean toward 220V with a single 110V shaver socket. Always confirm with your specific ship before sailing.

Are power strips allowed on cruise ships?

No. Power strips, surge protectors, and extension cords are banned on virtually all cruise lines as a fire hazard. The only permitted alternative is a compact multi-port USB charging hub that plugs directly into the wall with no extension cord.

Do I need a plug adapter for a cruise ship cabin?

US travellers on Royal Caribbean, Carnival, Norwegian, Celebrity, Princess, and Disney typically do not need a cabin adapter — US-style 110V outlets are standard. UK travellers will usually need a Type G to Type C adapter for the cabin unless sailing on Cunard. Always verify with your specific ship.

What adapter do I need for a Mediterranean cruise?

A universal travel adapter covering Types A/B, C/E/F, and G covers every Mediterranean destination. Italy's older Type L sockets are an exception — a universal adapter or a Type C to Type L adapter handles these. Buy before you sail; on-board prices are high.

How many outlets are in a cruise cabin?

Most standard cabins have 1–3 outlets. Newer ships add USB-A ports at the desk or bedside. This is the main reason a multi-port USB charging hub is the single most useful item to bring on a cruise.

Can I bring a surge protector on a cruise ship?

No. Surge protectors are prohibited on all major cruise lines. Bring a multi-port USB charging hub instead — these are permitted everywhere and do the same charging job without the surge-protection circuitry that ships ban.
