Cruise Approved Power Strip: What It Really Means and Which Products Work on Every Major Cruise Line

Quick Answer: A "cruise approved" power strip has no surge protection, no power conditioning, and no independent on/off switch or circuit breaker. Most major cruise lines — including Carnival, Norwegian, and Disney — allow a basic non-surge power strip in your cabin. Exception: Royal Caribbean banned all multi-plug outlets and power strips in September 2024, regardless of surge protection. For European or international cruises where cabin outlets are 220V, pair it with a DOACE cruise-approved voltage converter (LC-C30, LC-X30, HC-C11, or HC-X11). Do not bring the DOACE LC-X35 on a cruise — its built-in surge protection is banned by most cruise lines.

You pack four devices, two shared power banks, and a CPAP machine. Your cruise cabin has exactly two outlets. This is the moment most travelers realize they need a power strip — and then panic when they read that power strips might be banned on their ship.

The good news: most cruise lines do not ban power strips entirely. They ban a specific type: the surge-protected power strip. Understanding that single distinction is the difference between a confiscated power strip at the gangway and a fully charged cabin.

What "Cruise Approved" Actually Means

No cruise line publishes an official "cruise approved" certification for consumer power strips. The phrase is a shorthand that emerged from what cruise lines actually prohibit. The consistent rule across major cruise lines is this:

Why Surge Protectors Are Dangerous on Cruise Ships

This is the part most travel blogs skip. The ban is not arbitrary — it is rooted in how ship electrical systems actually work, and why a device designed to protect your home electronics can become a fire starter at sea.

Ship Power Grids Are Not Like Your Home

Your home connects to a large utility grid with a solid earth ground. Cruise ships use a fundamentally different design called an IT system (Isolated Terra), also known as a floating grounding system. In an IT system, the ship's generators are electrically isolated from the hull. There is no direct path to ground. This design is required by the SOLAS (Safety of Life at Sea) convention because it allows the ship to keep running even if one electrical fault occurs — critical when you are 200 miles from shore.

The problem: surge protectors contain components called Metal Oxide Varistors (MOVs) that are designed to shunt excess voltage to ground. On your home grid, this works perfectly. On a floating ship grid with no true ground reference, the MOV can interpret normal voltage fluctuations as surges. When an MOV fires repeatedly against a floating ground, it degrades. A degraded MOV can overheat, and in the worst case, ignite — inside a sealed cabin with limited ventilation and hundreds of sleeping passengers nearby.

Real Fires, Real Consequences

The cruise industry's aggressive stance on electrical safety is not theoretical. In 2006, a fire aboard the Star Princess killed one passenger, injured 13, and burned out 150 cabins. The UK MAIB investigation traced the origin to an unattended cigarette on a balcony — but the speed at which fire spread through cabin wiring and fixtures became the industry's wake-up call for tighter passenger electrical device rules. In 2013, the Carnival Triumph lost all power after an engine room fire, leaving over 4,200 passengers stranded at sea for days. The NTSB report documented systemic electrical maintenance issues, and the US Coast Guard issued a safety alert afterward. Neither fire was directly caused by a passenger surge protector — but both drove the industry to eliminate any unnecessary electrical risk in passenger spaces.

How the Ban Evolved: From "Bring Whatever You Want" to "All Confiscated"

To understand today's rules, you need the 20-year backstory. The current ban did not arrive overnight — it was built incident by incident, policy update by policy update, over two decades of cruise industry growth.

1990s–2000s: The No-Rules Era

In the 1990s, modern cruising exploded. Carnival, Royal Caribbean, and Princess completed mergers and IPOs. Ships grew massive — Royal Caribbean's Voyager of the Seas (1999) was the first to exceed 130,000 tons, carrying over 3,000 passengers. But no major cruise line published a "prohibited items" list for cabin electronics. The standard cabin had one or two 110V outlets plus a "shavers only" bathroom socket. Passengers borrowed power strips from each other and cabin stewards did not look twice.

Nobody realized at the time that ship electrical systems work fundamentally differently from home grids. That fact stayed invisible until accidents forced it onto the table.

2006–2009: Star Princess Fire and the First Prohibited Items Lists

The 2006 Star Princess fire (covered above) killed one passenger and burned 79 cabins. The origin was a cigarette, not electronics — but the investigation's aftermath changed everything. After the MAIB report was published, IMO's 2010 SOLAS amendment required all post-2008 cruise ships to use non-combustible balcony materials and extend fire suppression coverage to balcony areas.

More importantly for our story: Star Princess was the first time the industry recognized "cabin interior" as a serious fire origin category. Between 2007 and 2009, virtually every major cruise line published their first formal prohibited items list. Irons, coffee makers, space heaters, and open-flame devices appeared on those lists for the first time. Power strips were not yet banned — but cabin electronics as a risk class had officially entered the regulatory gaze.

2013–2015: Carnival Triumph and the Extension Cord Ban

The 2013 Carnival Triumph engine fire left 4,200 passengers stranded without power, sanitation, or air conditioning for five days. CNN dubbed it "The Poop Cruise." The NTSB investigation found systemic electrical maintenance failures. The fire itself came from a diesel return line — nothing to do with passenger devices. But the media firestorm and congressional hearings that followed turned "cruise ship safety" from an abstract concern into a cultural touchstone.

The direct result: Carnival's late-2013 prohibited items update banned "extension cords" explicitly for the first time. Other companies followed within 12–18 months. By 2015, crew community reports of "cheap surge protector power strips smoking in cabins" (specific incidents unconfirmed publicly) drove Royal Caribbean to add "surge protectors are not permitted in staterooms" to their passenger guidelines. Once Royal Caribbean moved, the rest followed — not because of an international mandate, but because of legal liability alignment: if one company bans it and yours doesn't, you carry extra legal exposure.

2018–2019: Industry-Wide Consensus (Without Industry-Wide Rules)

By 2018, all seven major cruise lines — Carnival, Royal Caribbean, Norwegian, Disney, Princess, Celebrity, and Holland America — explicitly banned surge protectors. MSC, with its European roots, followed in 2019. But here is the critical detail: there is no unified industry standard. The Cruise Lines International Association (CLIA) — which represents 95% of global cruise capacity — has never published a universal prohibited items list. CLIA focuses on health protocols, environmental standards, and COVID recovery. Cabin electrical rules remain each company's own policy, with slightly different wording, slightly different enforcement, and a new update each season.

This fragmentation is exactly why "Cruise Approved Power Strip" emerged as a consumer category on Amazon — travelers needed a simpler standard than seven different, vaguely-worded prohibited items pages.

2020–2022: The COVID Lax Window

When the global cruise industry shut down in 2020 and slowly restarted in 2021, enforcement collapsed. Skeleton crews, rushed training, extended embarkation times, and passenger complaint avoidance meant security screeners let almost everything through. On r/Cruise and Cruise Critic, a wave of posts appeared: "I brought my surge protector and nobody said anything." Some Amazon sellers cited these posts as evidence that their products were "cruise approved."

This created a dangerous three-way mismatch: official policy said banned, enforcement said allowed, and consumer perception said safe. That mismatch persisted until 2023 when training and screening returned to normal — and suddenly, travelers who had gotten away with it for two years were getting confiscated again.

2023–2026: New Ships, Stricter Enforcement, and Royal Caribbean's Full Ban

The 2023–2026 era brought a wave of mega-ships: Royal Caribbean's Icon of the Seas (January 2024, 7,600 passengers, world's largest), Princess's Sun Princess (February 2024), and Royal Caribbean's Utopia of the Seas (July 2024). These new ships made a significant design concession: more built-in USB-A and USB-C ports at bedside, and more 110V outlets per cabin than any previous generation. Icon of the Seas reportedly has multiple outlets and USB ports per berth — a deliberate response to the "not enough outlets" complaint that drove power strip demand in the first place.

But more outlets did not mean relaxed rules. In fact, enforcement tightened: newer X-ray machines have higher resolution, making it easier to spot MOV components inside power strips. And in September 2024, Royal Caribbean made the most aggressive policy move in the industry's history: banning ALL multi-plug outlets and power strips regardless of surge protection. The era of "bring a non-surge strip on RC" was over.

Cruise Line Rules at a Glance (2026)

Royal Caribbean: The Most Aggressive Policy Shift (September 2024)

Before September 2024, Royal Caribbean was one of the clearest cruise lines on this topic: their prohibited items page explicitly said "non-surge protector power strips are permitted." That changed when Royal Caribbean updated its banned items list to include "Extension Cords and Multi-Plug Outlets / Power Strips" as a category — no exceptions for surge-free strips. According to Cruises With Friends, this may be linked to newer ships like Icon of the Seas already having significantly more built-in outlets and USB ports per cabin. On Reddit r/royalcaribbean, travelers report confiscations at Miami, Port Canaveral, and Galveston — confiscated items are tagged and stored at the port, and you cannot retrieve them until disembarkation day.

If you are sailing Royal Caribbean, your best option is a USB-only charging hub (no AC outlets) or a DOACE GaN adapter, which provides USB-C/USB-A ports without any AC multi-plug configuration. Pure USB chargers are not listed in Royal Caribbean's banned category.

Carnival: Explicitly Allows Non-Surge Strips

Carnival takes the opposite approach. Their official policy states: "Power strips, multi plug box outlets/adaptors and extension cords (without surge protectors) are allowed on board when used with proper caution." Carnival brand ambassador John Heald has publicly confirmed this on social media: "We have not changed our rules and providing it does not have a surge protector and is in excellent working condition then pop it into your carry on and bring it on board" (CruiseHive report). That said, enforcement varies — on Cruise Critic forums, travelers report that strips with red indicator lights or switches sometimes get flagged even when they have no actual surge protection.

Norwegian Cruise Line: The Most Lenient Enforcement

Norwegian built its brand on "Freestyle Cruising" — fewer rules, more freedom. That cultural DNA extends to prohibited items enforcement. Norwegian's official policy mirrors other lines (surge protectors banned), but execution is the loosest of the seven majors. On r/Cruise, NCL is frequently recommended as "the line to choose if you're not sure whether your power strip is compliant." When security flags a borderline item, NCL crew often offer a choice — voluntarily discard or store it — rather than an outright confiscation.

For travelers with non-surge power strips, Norwegian is effectively a guaranteed pass. Even travelers who accidentally bring surge-protected strips report gentler handling compared to Royal Caribbean or Carnival ports.

Disney Cruise Line: Family-Friendly Hidden Leniency

Disney's passengers are families — iPads, Nintendo Switches, baby monitors, bottle sterilizers, cameras. The official policy bans surge protectors like everyone else, but enforcement visibly relaxes for families. Reddit reports describe security officers spotting a surge protector in a family's bag, pointing at the label, and suggesting they swap it for a non-surge strip from the gift shop rather than confiscating it outright.

Disney's other distinguishing feature: they proactively offer a "medical outlet" request process for CPAP users, baby equipment, and other medical devices. You can email the accessibility team two weeks before sailing and have a proper outlet configuration pre-arranged in your cabin. This is the only major cruise line that treats electrical accommodation as a service rather than a reactive problem.

MSC Cruises: The 220V Complication

MSC is the only major cruise line with extensive European routes where cabins may have both 110V and 220V outlets depending on ship age and itinerary. Mediterranean and Northern European sailings frequently feature Schuko-type 220V European outlets alongside (or instead of) North American 110V sockets. This means MSC passengers face an additional layer of complexity beyond "can I bring a power strip?" — they need to ask "will my 110V power strip survive a 220V outlet?"

MSC is also the only cruise line whose passenger guidelines explicitly remind travelers to "verify your electrical devices are compatible with the voltage available in your cabin." Enforcement is moderate, but security reportedly holds North American passengers to a slightly higher scrutiny standard than European passengers who are assumed to be more familiar with multi-voltage environments.

Princess Cruises: Massive Variation Between Old and New Ships

Princess's fleet spans three decades of shipbuilding. The brand-new Sun Princess (2024) has significantly upgraded cabin outlet configurations with multiple USB-C ports and additional 110V sockets. But older ships in the fleet — Crown Princess, Ruby Princess, and other Grand-class vessels from the 2000s — may have as few as one or two 110V outlets per cabin. This means your actual need for a power strip varies enormously depending on which Princess ship you book.

Princess's policy wording is among the most relaxed: "power strips with surge protection are not allowed." Enforcement matches — it is gentle, with confiscation rates among the lowest in the industry.

What Outlets Are Actually in Your Cruise Cabin?

The number and type of outlets varies significantly by ship age, cruise line, and home port. Knowing this before you pack determines whether you need just a power strip, or a power strip plus a voltage converter.

US-Based Ships on Caribbean and Alaska Routes

Most ships sailing from US home ports carry primarily 110V North American outlets (Type A/B) in cabins. Newer ships often add one or two USB-A or USB-C charging ports at the bedside. Expect two to four standard outlets in a typical interior or balcony cabin — rarely more.

European and International Ships

Ships sailing Mediterranean, Northern European, or transatlantic routes frequently carry a mix of 110V North American and 220V European outlets. If you are traveling from the US on a Mediterranean cruise, your 110V appliances plugged directly into a 220V European outlet will be damaged. This is where a DOACE voltage converter becomes essential — not just for extra outlets, but for safe voltage conversion.

How to Read a Power Strip Label Before You Pack It

The fastest way to tell whether a power strip is cruise approved: look at the label on the strip itself. You are looking for what is not there.

Many travel-focused power strips sold on Amazon explicitly state "no surge protection — cruise approved" in their product description. Search for those specific terms. If the listing does not explicitly say it has no surge protection, assume it does and verify before packing.

Products That Get Confiscated Despite Claiming "Cruise Approved"

On Amazon, searching "cruise approved power strip" returns dozens of products — but no product has ever received official certification from any cruise line. "Cruise Approved" is entirely a brand self-declaration. The real test is whether it passes security at the gangway, and community feedback from r/Cruise and Cruise Critic reveals three product types that regularly get confiscated despite "cruise approved" marketing:

1. Strips with a red illuminated switch — Older Bestek models and several Amazon white-label products. Security sees the light and flags it as a surge protector indicator, whether or not it actually has MOV components inside.
2. Strips with both USB and AC outlets where the packaging mentions "surge" — Some products have compliant hardware but catastrophic packaging copy. If the box or Amazon listing says "surge protection" anywhere, even in a disclaimer about what it does NOT have, rushed security staff may flag it.
3. Unknown brands with no UL listing — When security encounters an unfamiliar brand with no recognizable safety certification, the default response is to confiscate. Products from Anker, Belkin, and Tessan are more likely to pass because security staff recognize the brand.

For a detailed breakdown of each cruise line's specific policies and enforcement patterns, see our guide on cruise line power rules for Carnival, Royal Caribbean, and Norwegian.

The "Cruise Approved" Brand Landscape: Who Actually Passes Security

Search "cruise approved power strip" on Amazon and you will find about 12 different brands on the first page. None of them have received official certification from any cruise line. "Cruise Approved" is a self-declared marketing term. So who actually passes security consistently, and why?

Anker 511 USB Power Strip: The Smartest Positioning

Anker's 511 USB Power Strip (2023) may be the cleverest product design in this category. It has zero AC outlets — only 3 USB-A ports and 1 USB-C port, totaling 65W. Because it has no AC power passthrough at all, it structurally cannot contain surge protection components (surge protection only exists for AC circuits). Anker does not need to explain "we don't have surge protection" — the product is not even in the same regulatory category as a power strip.

User feedback on r/Cruise is overwhelmingly positive. It is repeatedly recommended as "the one product that will never get confiscated on any cruise line, including Royal Caribbean." The limitation is obvious: it only charges USB devices. Hair dryers, CPAP machines, curling irons — anything requiring AC power — cannot connect to it.

Bestek: The Legacy Brand with a Fatal Design Flaw

Bestek's 8-Outlet Travel Power Strip was the original "cruise approved" product, dominating this Amazon category from 2018–2022 with over 20,000 reviews. The product itself has no surge protection — it is technically compliant. But its older SKUs have a red illuminated power switch on the housing. As discussed above, cruise security officers use visual heuristics: red glowing switch = surge protector. The result is Bestek's product gets confiscated at a higher rate than it deserves.

Bestek updated some SKUs in 2024 with a white switch, but older units still circulate. If you own one, check whether your specific unit has a colored illuminated switch — and if it does, replace it before cruising.

Tessan: Policy Transparency as Strategy

Tessan's 2024–2025 cruise products take a different approach: their Amazon listings directly display screenshots of Royal Caribbean, Carnival, Norwegian, and Disney's official prohibited items pages as compliance evidence. This is the first time a brand has done the policy research for the consumer and published it inside the product listing. The strategy works — it shifts the burden of "is this cruise safe?" from buyer to seller, and has visibly eroded Bestek's market share.

Why Brand Recognition Matters at Security

An underappreciated factor in cruise security: brand familiarity affects confiscation rates. When a security officer encounters an Anker, Belkin, or Tessan product, they are more likely to recognize it and let it through. An unfamiliar white-label brand with Chinese characters and no UL marking triggers the "when in doubt, confiscate" default. This is not official policy — it is human psychology under time pressure with 4,000 passengers waiting behind you.

When You Also Need a Voltage Converter (International Cruises)

A non-surge power strip solves the "not enough outlets" problem for Caribbean and Alaska cruises with 110V cabins. But for European and international itineraries, a power strip alone is not enough. You also need to convert the 220V cabin outlet down to 110V before connecting US-only appliances.

This is where DOACE voltage converters serve a dual purpose on cruises: they step down voltage AND provide additional outlet access, eliminating the need for a separate power strip entirely for most travelers. If you are unsure whether you need an adapter, a converter, or both, start with our adapter vs converter guide. For a complete walkthrough of cruise-specific adapter and converter choices, see our cruise-approved travel adapter and converter guide.

Which DOACE Products Are Cruise Approved

DOACE Cruise-Approved Converter Recommendations

DOACE LC-C30 — Best for Most Cruise Travelers
Cruise approved (no surge protection). Steps 220V down to 110V with worldwide plug adapters included. Handles curling irons, shavers, small fans, and phone/laptop chargers within its wattage rating. A compact all-in-one solution for European cruise cabins.

DOACE LC-X30 — Best Compact Option
Cruise approved (no surge protection). 20% smaller and 30% lighter than the LC-X35, with a physical toggle switch for easy on/off control. Best choice for travelers prioritizing pack size. Not for high-watt hair dryers — use HC-X11 instead.

DOACE HC-X11 — For Hair Dryers and High-Watt Styling Tools
Cruise approved (no surge protection). Handles up to 2200W for mechanical-switch hair dryers, curling irons, flat irons, and straighteners. The right converter if you need to run a Conair, Revlon, or BaByliss hair tool from a European 220V cabin outlet. Not for Dyson or electronic-switch devices.

CPAP Machines on Cruise Ships

CPAP users have a different set of considerations. Most cruise lines make a medical exception for CPAP machines and will provide a dedicated outlet or extension upon request — but you must request this in advance through the accessibility or special needs department before your sailing date.

• Check your CPAP label first. Most modern CPAP machines (ResMed, Philips Respironics, etc.) are already dual-voltage (100-240V) and only need a plug adapter, not a converter, even on a 220V European cruise cabin.
• Request the medical outlet ahead of time. Contact your cruise line's accessibility desk when booking. Do not rely on finding an appropriate outlet in the cabin on embarkation day.
• If your CPAP is single-voltage 110V only (rare in modern machines), use an LC-C30 or LC-X30 — both cruise-approved — to step down from 220V.
• Do not use LC-X35 for your CPAP on a cruise. Despite being the recommended DOACE model for CPAP on land, the LC-X35's surge protection makes it non-compliant with cruise line policy.

The Counter-Argument: Is the Surge Protector Ban Overkill?

Any honest analysis must address the opposing view. On Reddit's r/electricians and r/ElectricalEngineering, and in ship electrical engineering communities, there is a consistent counter-argument: the cruise industry's ban is a liability-driven overreaction without sufficient engineering evidence.

Our assessment: The counter-argument is not wrong on the engineering details, but it underweights the unique context of a sealed ship at sea. The ban is a reasonable precaution given the stakes — and it is not going away. Plan accordingly.

Where This Category Is Headed: USB-C and the End of AC Power Strips at Sea

Zoom out five years and the "cruise approved power strip" as a product category is likely approaching its peak. Three forces are converging:

1. New ships are solving the outlet shortage from the supply side. Icon of the Seas, Sun Princess, and other 2024+ vessels have more USB-C and USB-A ports built into every berth. The "two outlets per cabin" problem that created demand for power strips is being designed away.
2. Consumer devices are consolidating on USB-C. Phones, tablets, laptops, cameras, earbuds, power banks — 95% of what travelers need to charge now runs on USB-C PD. The need for AC outlets is shrinking to high-watt devices like hair dryers and CPAP.
3. GaN multi-port chargers are the next-generation "cruise power strip." A DOACE 100W or 140W GaN adapter with 3–4 USB-C/USB-A ports plugs into a single cabin outlet and charges everything simultaneously — no AC multi-plug, no surge components, no regulatory risk. These devices sidestep the entire power strip debate.

The smart move for 2026 cruise travelers: combine a GaN multi-port charger (for all USB devices) with a single cruise-approved voltage converter (for any remaining AC-only devices like hair tools). This two-device setup eliminates the need for a traditional power strip entirely on most voyages.

Your Cruise Power Packing Checklist

Run through this before you zip your suitcase:

1. Check your cruise cabin outlet type. Search your ship name plus "cabin outlets" or call the cruise line. Know whether it is 110V, 220V, or both.
2. If 110V cabin: Bring a basic non-surge power strip. Check the label — no surge protection, no independent breaker.
3. If 220V cabin (European cruise): Bring a DOACE cruise-approved converter (LC-C30, LC-X30, or HC-X11 depending on your devices). You may not need a separate power strip — the converter adds outlet access.
4. Do not pack LC-X35 unless you confirmed with your specific cruise line that it is acceptable. Its surge protection is banned by most lines. See our LC-C30 vs LC-X35 vs LC-X80 comparison to understand the differences.
5. CPAP users: Email the accessibility desk now, not the week before. Confirm the outlet situation in writing.
6. Dual-voltage devices (phones, laptops, cameras) only need a plug adapter even in a 220V cabin. The DOACE 100W GaN adapter is cruise-approved and covers all charging needs.

FAQ

Can I bring a power strip on a cruise ship?

On most cruise lines — yes, if it has no surge protection, no power conditioning, and no independent on/off switch or circuit breaker. A basic pass-through multi-outlet strip is allowed by Carnival, Norwegian, Disney, Celebrity, Princess, and MSC. The exception is Royal Caribbean, which banned all multi-plug outlets and power strips in September 2024, regardless of surge protection.

Is my surge protector banned on a cruise?

Yes, on virtually all major cruise lines. Surge protectors contain components that can fail and create a fire hazard in enclosed ship cabins. The ban covers any device labeled as a surge protector, surge suppressor, or power conditioner, regardless of brand or size.

Does Royal Caribbean allow power strips?

No — not since September 2024. Royal Caribbean updated its prohibited items list to ban all extension cords, multi-plug outlets, and power strips, whether or not they have surge protection. Before this change, non-surge strips were explicitly allowed. If you are sailing Royal Caribbean, consider a USB-only charging hub or a DOACE GaN adapter instead.

Is the DOACE LC-X35 cruise approved?

No. The LC-X35 has built-in surge protection, which is banned by most cruise lines. Use LC-C30, LC-X30, HC-C11, or HC-X11 instead — all four have no surge protection and are cruise-approved.

Do I need a voltage converter for a European Mediterranean cruise?

Likely yes if you plan to use 110V-only appliances such as American hair dryers, curling irons, or straighteners. European cruise cabins often have 220V outlets. Check your specific ship's outlet configuration. A DOACE LC-C30 or HC-X11 (cruise-approved) will step down the voltage safely. For dual-voltage devices like phones and laptops, you only need a plug adapter.

What outlets are in cruise ship cabins?

It varies by ship and route. Caribbean and Alaska routes from US ports typically have 110V North American outlets (Type A/B), with 2–4 outlets per standard cabin. Mediterranean and European routes may have a mix of 110V and 220V European outlets. Newer ships increasingly add USB-A and USB-C bedside ports. Always verify before sailing.

Can I use my CPAP on a cruise ship?

Yes, but arrange it ahead of time. Contact your cruise line's accessibility department before the sailing date to request a CPAP-friendly outlet or distilled water. Most modern CPAP machines are dual-voltage and only need a plug adapter, not a voltage converter. If your CPAP is 110V-only, use a cruise-approved DOACE converter (LC-C30 or LC-X30), not the LC-X35.

Can I use a power bank on a cruise ship?

Yes, with capacity restrictions. Most cruise lines follow airline rules: power banks with lithium batteries must be kept in carry-on luggage, not checked bags, and are typically capped at 27,000 mAh (100Wh). Power banks are fine to use in your cabin and onboard the ship.

My power strip has no surge protection but has a red light switch — will it get confiscated?

Possibly. On Reddit r/Cruise and Cruise Critic, travelers report that power strips with illuminated switches or red indicator lights are sometimes flagged by security — even when they contain no actual surge protection. Security officers often make visual judgments, and a glowing switch looks like a surge protector indicator. To avoid problems, choose a strip with no switch, no light, and a plain appearance.

What happens if my power strip gets confiscated at boarding?

Most cruise lines tag the confiscated item and store it at the port or in a secure area onboard. You cannot use it during the cruise. It is typically returned only on disembarkation day when you collect it with your luggage tag receipt. On a 7-day voyage, that means 7 days without it.

Are surge protectors really dangerous on ships, or is the ban overkill?

Some electrical engineers argue that modern surge protectors built to the UL 1449 4th Edition standard (effective since 2014) have improved fail-safe mechanisms that disconnect the circuit when MOVs degrade, reducing fire risk. That is a fair technical point for home use. But cruise ships operate on floating IT grounding systems where MOV behavior is fundamentally different from land grids. The cruise industry's position is a precautionary one — and given the consequences of a cabin fire at sea with thousands of passengers aboard, the ban is unlikely to be relaxed anytime soon.
