Or buy something that's locally available and serviceable.

1)Socket alone will not help. It is just a universal pin which can take different types of plugs.
2)A step down transformer (110v converter) can be used depending on load. Ranges from 250 VA - 10KVA (Rs.250-Rs.20000).
2.a - 250 vA can be for single connection for small gadgets like phone, etc.
2.b - 10kva can be installed in main unit in dedicated phase (out of 3 phase supply) and can have as many 110V plug pins.
Need to custom order this product and may not be in stores.
I have 2.b for entire house ranging from cell phone, Tv, washer dryer, kitchen gadgets.

Thanks

chennainanban - could you pls. let me know where in chennai can we custom order the 2.b 10KVa product?

It is not a good idea to have a huge 10KVA transformer feeding multiple sockets at home. Most transformers you get here will have some inefficiency. My guess is at least 10% is wasted as heat. It is a much better option to have point of use transformers if possible. This is best done at construction stage where all these transformers can be stashed away in a secluded area. For those who have already built or own a flat, you can segregate the tasks into two fold (a) under 50W (e.g. electric razors, battery chargers etc) and use a diode based voltage converter.
(b) Heavy duty products - receivers, plasma tv etc. For the heavy appliance, group them into areas e.g. if you have a TV and a receiver in your bedroom, then 750W transformer should suffice for both.


When you add up all the wattage of all these individual transformers, you would have used less than 2KW of transformer. You not only save several thousand rupees upfront, but end up saving several thousand rupees per year in utility bills.

The NPV of this idea is over one lakh rupees.

That kind of money should buy a lot of high quality high wattage 220V appliances (such as a dryer, hairdryer, or blender).

To the extent possible try to use 220V system. E.g if you have a cordless phone, switch the adapter to a 220V, which are widely available. Nowadays most camcorder and camera chargers can use 100 - 220V and can be plugged in directly into a local socket with an adapter pin.

I have tried all of these (still have a 2KV converter for my old home theater!!). Best option is to find a good electronics shop and get your equipment converted to 220v!! I got it done from a shop in Jayanagar (it seems to be closed these days)....they call it "re-winding" the transformer and then it works like a charm. I think I paid about 500Rs for it!
