Royal Caribbean drew protests from guests after announcing a fleetwide ban on multi-plug outlets. The cruise line has since clarified what guests can and can’t bring onboard, offering flexibility on a restrictive guideline.

The Miami-based cruise operator initially listed “multi-plug outlets” on its list of prohibited items onboard but after netizens became concerned about what it would mean for their gadgets and devices, the company amended its rules and mentioned what it does allow.
Instead of “multi-plug outlets,” the prohibited item has been replaced with “electrical extension cords.” Royal Caribbean says that “power strips/surge protected strips and multi-plug outlets” cannot be brought onboard.
However, it added, “We do allow consumer type power conversion device USB charger (multi-plug blocks on which the outputs are for USB cables).”
What This Means for Royal Caribbean Guests
Passengers can bring power adapters, even if they have many ports, as long as they only power USB devices. Since smartphones, various gadgets, and a handful of small appliances can now be powered through USBs, the concession is an acceptable middle ground for most cruisers.
Multi-plug blocks that combine USB ports with regular outlets are not allowed.
As an additional measure, the cruise line reminded vacationers that these USB wall chargers “must be stamped with US/Europe recognized Conformance Marking to demonstrate compliance with Electrical Safety standards.”
Why Ban Multi-Plug Blocks, Extension Cords, and Surge Protectors?
Multi-plug blocks, extension cords, and surge protectors typically draw more electricity, compromising the vessel’s electrical system while increasing the likelihood of fire-related incidents.
In contrast, USB chargers use significantly less electricity, making their loads more manageable for the vessel’s electric grid. USB phone chargers can draw up to 20 watts of power, but most only need 5 watts.
Regular adapters and extension cords support considerably larger and more power-hungry electronics, which may require over 200 watts of electricity.
If you need an extension cord for a health-related concern—like a CPAP machine for sleep apnea—fill out the Special Needs Form 30 to 60 days before your sailing date and Royal Caribbean will supply you with one.
Cruise Ships Have Final Say
Regardless of which cruise line you sail with, checking their list of allowable items is always a good idea. Each cruise operator can still prevent you from bringing other items onboard if they think it’s necessary.
In Royal Caribbean’s case, the company’s rules state, “Some items that are not specifically on the list may be prohibited if they are deemed questionable by the Staff Captain and Security Officer.”
Cruise lines must carefully follow health, safety, and legal regulations.
