Electricity in India is 240 Volts, alternating at 50 cycles per second. You will require a voltage converter if you are carrying a device that does not accept 240 Volts at 50 Hertz. To adjust your device according to the power and voltage in India, the following three types of Voltage converters may be used:
This type of converter usually supports approximately 50 -1600 Watts. They are lightweight. You can easily use this converter for high-wattage electrical appliances like hair dryers and irons. But, you can use them for short periods only and they are not ideal for digital devices.
Transformers support low watt rating, around 50 - 100 Watts. Generally, you can use them continuously. Also, they provide better electricity for low wattage appliances like battery chargers, radios, laptop computers, cameras, mp3 players and camcorders. Their drawback is the low wattage and heavy weight.
Combination converters are also manufactured by some companies. They are a combination of a resistor network and a transformer in the same package. You can easily switch between the two modes. If you need both types of converters, then it is better to buy this combination converter.
Outlets in India generally accept the following types of plug:
