You need to get a voltage converter which converts 220 volts to 110 volts to be given to the particular electronic item you purchase in US, to be used in india. You cannot simply plug in the electronic item bought here in to a power socket in india. The item will definitely burst.
Indian voltage is 220V..In us it is 110Volts. You need to buy a step-down transformer (voltage converter) which makes the 220 volts in indian socket to 110 volts to be given to US made item.
The cost of the converter varies ,depending on the power wattage of the item you are going to use it for. Normal range would be 3000 rupees to 6000 rupees..
Non-electronic items are the best bet to be gifted to be used in india.
