    Though lots of search results on the internet says you can convert 220v to 110v at an outlet, a local electrician and my EE grad nephew in Cebu both say No.
    The electrician and the EE are correct. You can not do that.

    So what's different about the way Noreco delivers power that prevents it?
    The Philipines use 220 Volts single phase. North America uses 120 Volts, 2 phase (180 degrees apart). It is technically called a "3 wire Edison" connection. Google 3 wire Edison.
    The 3 wire Edison connection is often found in North American kitchens and cloths dryer outlets.

    I did find a Yahoo Answers ? where the guy in Phils asked if he could disconnect one wire and cap it, then run a wire from the empty side of the outlet to a copper ground stake (which I would want to do anyway) .. He was told it's a lousy idea but it'd work.
    That information is wrong. You will still end up with 220 volts that will drop off close to 0 volts when th appliance is turned on and the potential to get a nasty shock.

    I have a 1200w 110v small cooking appliance coming and if I could just add a small box to a heavy duty ext cord and proper breaker etc it'd be a lot cheaper than buying a 1500w power supply.

    Your best bet is to buy a step down transformer.
    NOTE:You can buy an AVR which often will have a 11o volt output but a 1500 VA (watt) 220v AVR will only supply 750 VA (watt) at 110 volts.Check the specs before you buy.

    &Imps idea to make the 110 volt appliance cords will save you a lot of grief.

    Simple solution, just go to Polaris Equipment and turn right when you enter the store. You will see a row of converters that will do the job for you. They can put an external female outlet on it for you (wired 110).

    Then plug your 110 stuff into it directly. Also they can build you a proper extension cord with as many outlets as required. Great store, great service. I did this 5 years ago and have never lost an appliance to power surges or power fluctuations. Hope this helps...
