Adaptors vs Converters vs Transformers

I was doing some research on what converters / adaptors / transformers are needed for Europe. Note that most newer computers, cameras, phones, etc. are compatible with European voltage and don't need a converter (you'll only need the adaptor) so check your equipment before you leave. Adaptors are only $2-$3 vs. converters which are closer to $30. Hopefully I summarized this right.

There are two distinct types of appliances: Electric and Electronic.

Converters are for single volt Electric products with simple heating devices and/or universal motor products such as garment steamers, irons, curling irons, etc. These products are generally used for short periods of time. Step-down converters convert 220/250V foreign electricity down to 110/125V domestic electricity by cutting the number of volts flowing into the appliance in half. The wattage of the appliance being used determines which Travel Smart by Franzus converter should be used. Check your appliance’s rating label for the wattage.

• Adaptors change the prongs for both electric and electronic appliances so they fit into a European outlet.
• Converters are for single volt Electric products with simple heating devices and/or universal motor products such as garment steamers, irons, curling irons, etc. These products are generally used for short periods of time. Step-down converters convert 220/250V foreign electricity down to 110/125V domestic electricity by cutting the number of volts flowing into the appliance in half.
• Transformers are for single volt appliances with Electronic circuitry (computer chips or integrated circuits) such as computers, fax machines, answering machines, T.V.'s, power tools, cameras, phones, etc. Like converters, transformers can either step-down the voltage or step-up the voltage. Do not use a converter with these products.

After reading customer reviews for multiple converters, it sounds like if your appliance is marked 60 Hz, and not 50/60 Hz, you run the risk of burning up something inside regardless of whether or not you use a converter. Every single adaptor had a least one customer with a mishap.

The highest ranked kit on Amazon (although it only has 13 reviews) was the Samsonite Converter/Adaptor Plug Kit.
