Hey I came across your response looking for a pretty specific answer. My wife and I are going to eventually wire the house for 110v, but I wondered if you had any issues with the frequency difference? 50hz vs 60hz to be specific.Depends on what you are trying to do. You can get a coverter which is really for things like razors, etc. you only use once a day. If you have say a tv or some other major appliance you need to get a transformer which you can buy in Argentina. Transformers are sized in watts. To calculate the watts of a particular appliance the formula is Amps x voltage = watts(i.e. an appliance that takes 5 amps would need approximately a 600 watt transformer 5 amps X 110 volts = 550 watts).
You can buy individual transformers for each appliance or buy one big one and have your house or apartment wired to run 110. I did that once there as I had a bunch of stuff from the states. You just need to make sure you know which outlets are 110 versus 220 if you do this.
Hi Rich. Thanks for the advice! Unfortunately Frequency Converters are much much more expensive than Voltage Transformers. We have a 2000W voltage transformer already, but the frequency converters run in the several hundreds of dollars.contact ebay and look for ; Voltage & frequency Converter from 120V and 60HZ to 220 Volt 50HZ MAX 300 WATT runs like $85 bucks.
