Although outlets in India should run at 240V, power outages and power spikes are extremely common. This is because the reliability of India’s power supply varies widely, from state to state, right across the country, due to a lack of proper infrastructure and wiring. Even “electrical thievery” is common in India, where poor locals steal the power by hooking their home electrical power line to the overhead city lines without paying for it!
How much the power can spike during a given day varies greatly from place to place. The bigger cities’ power supply tends to be a little more stable, while the more remote “outback” locations tend to be more unstable. In some places, we would suggest it is erratic and unpredictable at best.
No matter where you are, it’s important that you never rely on the stability or dependability of the power supply.
