Using a surge protector on a cruise ship is not recommended and it is usually not allowed. A surge protector, also known as a power strip, is designed to protect electronic devices from surges in electrical power that can cause damage or even destruction of equipment.
Cruise ships are made of metal and are surrounded by saltwater. This combination creates a dangerous environment for electronic devices as the saltwater can cause corrosion of electrical components and the metal structure of the ship creates an electrical current that can be very dangerous to unprotected devices.
The surge protectors used in residential settings are not suitable for use on cruise ships because they are not designed to withstand the high voltages encountered in these environments. The high voltage environment can cause the surge protector to short-circuit, which could potentially lead to an electrical fire or other damage to electronics on board.
The best way to protect your electronics while on a cruise is to use an Uninterruptible Power Supply (UPS). A UPS provides clean, filtered power with no risk of spikes or surges that could potentially damage your equipment. It also provides battery backup in case of a power outage, so you don’t have to worry about losing valuable data due to an unexpected loss of power.
Conclusion:
Using a surge protector on a cruise ship is not recommended due to the high voltage environment which could short-circuit the device and lead to potential damage or destruction of equipment. The safest option is to use an Uninterruptible Power Supply (UPS) which provides clean filtered power with no risk of spikes or surges, and also provides battery backup in case of power outages.
