TV is not a problem, Washers are easy with a transformer. All of your
kitchen apps including the toaster are easy if you stop at Home Depot in the States, pick up about a 4 foot wire mold, plug strip and fasten the US wire mold [out of sight] under the kitchen cabinets, the plug the wire mold into a 2000 watt transformer and run the fridge and all other kitchen appliances. It is easy and works great.
Now............ the clothes dryer is a pain in the ass, many shops here will tell you that they can convert the dryer. And only one or two really know how. Argentine 220 is 50 cycle and single phase, US 220 is 60 cycle and two phase. And a US 220 dryer uses the 220 only for the cal rods, the motor, lights , timer and such are 110. So it's a tricky job. It will cost a fortune to convert properly. Bring a GAS dryer and save yourself a nightmare and allot of money and time.
