Travel voltage converters are not designed for continuous use as oppose to the larger transformer which can be used continuously. Travel voltage converters also have very small capacity and usually range from 30W to 200W max. The 1600W or 1875W travel voltage converter is not an actual voltage transformer, it is designed specifically for heat producing (purely resistive) items only such a hair dryer, irons, heating pads, etc.. Do NOT use 1600W or 1875W setting of a travel voltage converter with electronic items or any items with electronic circuitry or chipset.
Your device should say the range of voltage it can handle. This should be on a sticker or on the plug or device itself. Some devices are internationally compliant and can handle the voltage (my iPhone charger is fine to use without a converter). Others WILL NOT and you will need to purchase a converter or use a different device. (Kinda’s Chi straightener actually started smoking in Wales and was destroyed. She now travels with a tiny straightener that is made to handle both voltages).
We've selected some of the best voltage converters below. But if you're not sure what type of voltage converter or adapter you need - this handy Voltage Converter Guide explains all
The amount of current for this type of device is normally high enough that you probably indeed need an "industrial" type step-up transformer (check the wattage of your device). It's possible that the current draw of such a transformer would overdo what's available in a cruise ship stateroom anyway. And if nothing else, the cost, size, and weight of such a transformer will make it an unattractive option. My advice would be simply to use a 110V appliance, which can probably be purchased on-board the ship, and understand that it will be inferior.
