Travel Voltage Converter 500W

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.

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.

500W or more (even 500W) is what you should get... Ideally more than 500W travel voltage converter would make it a safer bet for you. I am not sure about B'lore, but in Chennai Mercy electronics would be the place to go to. Else any good electronics store in the city. Whenever I get electrical stuff from US the first thing I look up are the tech specs, I get a sigh of relief if the voltage range is 110-240V. Frequency doesn't affect most modern electronic equipment like phone chargers, laptops, cameras, etc. But from my experience one has be to be careful while buying electrical clocks from US. Transformers only convert the voltage, not the frequency. The frequency cycle difference will cause electric clocks and timing circuits to keep incorrect time, Indian clocks will run faster on 60 Hz electricity and American clocks will lose some 10 minutes every hour when used in India, and one may end up sleeping more.

A voltage converter is an electric power conversion device which is used to change the electrical output of a power source. The most common use for these converters is to change the voltage from 220 volts down to 110 volts, or from 110 volts up to 220 volts. When an electronic device, appliance or power tool was built for a specific voltage which is not available, the only way the device can be used is by converting the power up or down to the correct level. The need for a voltage converter often arises for people who travel abroad or take overseas vacations and bring electronics along with them.
