Royal Caribbean does allow passengers to bring power banks on board, as long as the devices comply with maritime safety guidelines. Because most power banks use lithium-ion batteries, they fall under strict international safety regulations. These rules are designed to prevent overheating, fire hazards, and electrical malfunctions while at sea.
This means your portable charger is welcome on board, but it must meet specific quality, size, and usage standards. As long as your power bank is properly labeled, not damaged, and within the acceptable capacity limit, it will pass security without any issues.
Lithium-ion batteries can be extremely efficient but also sensitive. When exposed to damage, improper charging, excessive heat, or compression, they may short-circuit. To avoid these risks, cruise lines follow safety frameworks similar to airlines. Royal Caribbean enforces guidelines to protect passengers, crew, and ship equipment from battery-related incidents.
Maritime safety policies apply to:
Power banks
Laptops
Tablets
Drones
Electric scooters
E-cigarettes
Certain medical devices
Understanding these regulations helps ensure your power bank is both safe and approved for travel.
Royal Caribbean follows common transportation guidelines, typically allowing power banks up to 100Wh (watt-hours) in capacity without needing prior approval. This covers most of the power banks sold for mobile devices, including:
5,000 mAh
10,000 mAh
20,000 mAh
26,800 mAh models
Higher-capacity devices, especially commercial or industrial chargers, might exceed allowed limits and be rejected.
If your power bank shows mAh but not Wh, use this formula:
Wh = (mAh ÷ 1000) × 3.7
Example:A 20,000 mAh power bank = (20000 ÷ 1000) × 3.7 = 74WhThis is well within Royal Caribbean’s acceptable capacity.
Large units—like those used for laptops or mini portable stations—may be flagged by security. If the power bank:
Has no visible battery label
Exceeds standard capacity
Appears damaged
…it may be confiscated for safety.
These everyday power banks used for phones or headphones are fully permitted.
Allowed, as long as capacity is within limits.
Permitted, but must follow the same lithium battery rules.
Some types raise safety risks and may be rejected, including:
These are essentially mini-generators and may exceed wattage limits.
Security must confirm battery capacity before allowing them on board.
Swollen or cracked devices will be confiscated immediately.
Royal Caribbean requires all lithium batteries to be stored in a carry-on, not checked luggage. Cargo areas may get hot, and stored luggage may shift, risking battery damage.
Screening officers might request to inspect your power bank during embarkation.
Not mandatory, but helpful—it makes inspections faster.
Royal Caribbean cabins use standard US-style outlets. If you are traveling internationally, pack an adapter for your own devices.
Avoid placing power banks on couches, beds, or carpets during charging.
Unattended charging can increase heat buildup.
Deck areas, splash zones, and beaches are risky spots. Always keep electronics dry.
Loose wires in public spaces can be tripping hazards.
Ship common areas such as cafés, lounges, and libraries may have limited charging plugs, and crowds compete for them. A power bank helps you stay powered without occupying shared outlets for long.
It is safer and more considerate.
Port days can last several hours, and many travelers use their smartphones for:
Navigation
Photos and videos
Booking activities
Messaging the ship app
Emergency communication
A reliable power bank ensures you never run out of charge while exploring.
Useful for families who travel together or for charging more than one device on long excursions.
Sun exposure on open decks can overheat your power bank quickly.
Keeps dust, water, and impact damage under control.
Great for occasional charging of phones.
Ideal for long days in port and frequent device use.
Maximum safe capacity for serious travelers.
Best for modern smartphones, tablets, GoPros, and small cameras.
Suitable for older Android devices.
Useful for couples, families, or travelers with multiple devices.
Necessary for safe travel.
Prevents thermal-related damage.
Helps monitor battery levels easily.
Choose well-known manufacturers to avoid risks associated with cheap or fake batteries.
Heat, pressure, and shifting bags pose a hazard.
Frayed or exposed wires can spark or overheat.
For both security and hygiene reasons.
Drawers, bags, or under pillows can trap heat.
Cruise ships are safe, but items can be lost or mistakenly taken.
Yes, as long as each is within the allowed capacity and stored in your carry-on.
Absolutely—power banks are extremely useful on island days.
Only if it is damaged, oversized, or missing battery labels.
Usually no. Royal Caribbean ships rarely sell portable chargers.
Modern ships have several outlets and USB ports, but older ones have fewer. A power bank helps in both cases.
