India vs US voltage: what changes for your kitchen
Indian homes run on 230 volts at 50Hz. American homes run on 120 volts at 60Hz, with different plugs. Here's what that does to the appliances you bring or buy.
| India | United States | |
|---|---|---|
| Voltage | 230V | 120V |
| Frequency | 50Hz | 60Hz |
| Plugs | Types C, D and M (round pins) | Types A and B (flat pins) |
| Kitchen outlet | 6A and 16A sockets | 15A or 20A circuits |
A 230V appliance on 120V
It gets roughly half the voltage it was designed for. Heating appliances give off about a quarter of their usual heat, because heat scales with the square of the voltage. Motors run slow and weak and can overheat when loaded, which is the usual fate of a mixer grinder plugged in without a transformer.
A 120V appliance in India
The reverse is worse: nearly double the voltage can burn out the motor or element quickly. If you're sending a 110V mixer grinder to family in India, it needs a step-down transformer there.
Why 50Hz vs 60Hz matters for some machines
Most mixer grinders use universal motors, which run on either frequency. Wet grinders and some fans use induction motors, which spin 20% faster on 60Hz. Electronics with a switching power supply, like phone and laptop chargers, accept 50 or 60Hz and usually say so on the label.
Dual-voltage is common in electronics, rare in kitchens
Chargers, laptops and many TVs are labeled 100–240V and need only a plug adapter. Kitchen appliances almost never are. Check the plate with the rating plate checker.
What to buy here
For anything with a motor that you use every day, buy the 110V version: mixer grinders and wet grinders. For chargers, a grounded India-to-US plug adapter is enough.
