Check your notebook adapter to see if it takes 220V. Most laptops do. The adapter would specify something as "Input 100-240V"
- If you see that, then all you need is to get a "round to flat pin converter in India" or buy interchangeable pin converters here in US (check Radioshack, maybe Walmart or local electronics\electrical stores).
- If not, then you would need to buy a converter too, that steps down the voltage from 220 to 110 (US voltage).
